Developmental expression patterns of Bcl-2, Bcl-x, Bax, and Bak in teeth. (1/1158)

The ontogenic profile of expression of four members of the Bcl-2 family (Bcl-2, Bcl-x, Bax and Bak) was examined in the mouse by immunohistochemistry using paraffin sections. All four members were expressed in changing patterns during critical stages of tooth morphogenesis. Expression was detected in epithelial cell populations including the dental lamina, internal dental epithelium (IDE; differentiating ameloblasts), stratum intermedium and stellate reticulum cells, as well as in the condensed dental mesenchyme. The temporo-spatial localization of the various members of the Bcl-2 family in dental epithelium and mesenchyme showed striking overlapping areas but often their expression patterns differed. In general, contemporaneous co-expression of the Bcl-2 and Bax proteins, and of the Bcl-x and Bak proteins was noted in various types of cells during the developmental process, with the intensity of Bcl-2>Bax and of Bak>Bcl-x. Expression was pronounced at sites where interaction between surface ectoderm and induced mesenchyme takes place, and at the enamel knot, which is regarded as organization/regulating center for tooth development. Around birth, after the structural maturation was accomplished, the expression was down-regulated. The absence of elevated expression of each of these four members of the Bcl-2 family after birth in the teeth suggests that these proteins are relevant during the accomplishment of the basic architecture but not once the structure of the tooth is established.  (+info)

Australopithecus garhi: a new species of early hominid from Ethiopia. (2/1158)

The lack of an adequate hominid fossil record in eastern Africa between 2 and 3 million years ago (Ma) has hampered investigations of early hominid phylogeny. Discovery of 2.5 Ma hominid cranial and dental remains from the Hata beds of Ethiopia's Middle Awash allows recognition of a new species of Australopithecus. This species is descended from Australopithecus afarensis and is a candidate ancestor for early Homo. Contemporary postcranial remains feature a derived humanlike humeral/femoral ratio and an apelike upper arm-to-lower arm ratio.  (+info)

Clinical trial of three 10% carbamide peroxide bleaching products. (3/1158)

BACKGROUND: A profusion of commercial bleaching systems exists on the market today, but there are few clinical comparisons of these systems. METHODS: In this study, three different commercial 10% carbamide peroxide bleaching systems were used by 24 patients in an overnight protocol for two weeks. Each patient used two of the bleaching products simultaneously in a side-by-side comparison. RESULTS: The mean onset of tooth whitening was 2.4 +/- 1.7 days. Tooth sensitivity was the most frequent side effect, as 64% of the patients reported tooth sensitivity occurring after 4.8 +/- 4.1 days and lasting for 5.0 +/- 3.8 days. Although intrapatient differences were recorded for the three commercial 10% carbamide peroxide bleaching systems by the patients, there were no statistical differences in the time of onset of subjective tooth whitening and the onset, frequency and duration of tooth sensitivity among the three commercial bleaching systems when compared pairwise or independently (p < 0.05). CONCLUSION: Selection of which bleaching product to use should be based on the concentration of the active ingredient, the viscosity of the product and other marketing features. Further research is needed to investigate the causes of tooth sensitivity and methods to reduce its severity and frequency.  (+info)

Blastogenic response of human lymphocytes to oral bacterial antigens: comparison of individuals with periodontal disease to normal and edentulous subjects. (4/1158)

Cell-mediated immunity in humans to antigens derived from oral plaque bacteria was investigated by using the lymphocyte blastogenesis assay. Subjects with varying severities of periodontal disease including normal, gingivitis, periodontitis, and edentulous were compared. Mononuclear leukocytes were separated from peripheral blood and cultured with antigens prepared by sonication of Actinomyces viscosus (AV), Actinomyces naeslundii (AN), Veillonella alcalescens (VA), Leptotrichia buccalis (LB), Bacteroides melaninogenicus (BM), and homologous dental plaque (DP). The lymphocyte response of subjects with gingivitis or periodontitis was significantly greater than that of normal subjects to antigens of AV, AN, and DP, but did not differ from the response of edentulous subjects. Periodontitis subjects were significantly more reactive than edentulous and normal subjects in response to VA, LB, and BM. These findings suggest that the tested gram-negative bacteria and the host response they evoke are associated with advanced periodontal destruction.  (+info)

Immunohistological distributions of fibronectin, tenascin, type I, III and IV collagens, and laminin during tooth development and degeneration in fetuses of minke whale, Balaenoptera acutorostrata. (5/1158)

The immunohistological distributions of fibronectin, tenascin, type I, III and IV collagens, and laminin were observed in the tooth buds of fetuses of minke whale, Balaenoptera acutorostrata. Distributions of extracellular matrices (ECMs) examined in this study except for tenascin were generally similar to those of terrestrial mammalian species during development of the tooth bud. Tenascin in the fetuses of minke whale showed characteristic distributions in the dental lamina and the enamel organ in the early tooth developmental stage. In the physiological degeneration stage of tooth bud development, immunoreactivity of the ECMs were very weakly and limitedly detected in the dental papilla and the surrounding mesenchyme. Immunoreactivity of tenascin and type I and III collagens were positively detected in the developing baleen plate germ which was associated with the degenerating tooth bud. These findings suggested that expressions of the ECMs were related to the formation of the tooth bud and baleen plate germ, and that the lack of the ECMs was related to the degeneration of the tooth bud in the fetal minke whale.  (+info)

Cbfa1 is required for epithelial-mesenchymal interactions regulating tooth development in mice. (6/1158)

Osteoblasts and odontoblasts, cells that are responsible for the formation of bone and dentin matrices respectively, share several molecular characteristics. Recently, Cbfa1 was shown to be a critical transcriptional regulator of osteoblast differentiation. Mutations in this gene cause cleidocranial dysplasia (CCD), an autosomal dominant disorder in humans and mice characterized by defective bone formation. CCD also results in dental defects that include supernumerary teeth and delayed eruption of permanent dentition. The dental abnormalities in CCD suggest an important role for this molecule in the formation of dentition. Here we describe results of studies aimed at understanding the functions of Cbfa1 in tooth formation. RT-PCR and in situ hybridization analyses show that Cbfa1 has a unique expression pattern in dental mesenchyme from the bud to early bell stages during active epithelial morphogenesis. Unlike that observed in osteoblast differentiation, Cbfa1 is downregulated in fully differentiated odontoblasts and is surprisingly expressed in ectodermally derived ameloblasts during the maturation phase of enamel formation. The role of Cbfa1 in tooth morphogenesis is further illustrated by the misshapen and severely hypoplastic tooth organs in Cbfa1-/- mice. These tooth organs lacked overt odontoblast and ameloblast differentiation and normal dentin and enamel matrices. Epithelial-mesenchymal recombinants demonstrate that dental epithelium regulates mesenchymal Cbfa1 expression during the bud and cap stages and that these effects are mimicked by the FGFs but not by the BMPs as shown by our bead implantation assays. We propose that Cbfa1 regulates the expression of molecules in mesenchyme that act reciprocally on dental epithelium to control its growth and differentiation. Taken together, our data indicate a non-redundant role for Cbfa1 in tooth development that may be distinct from that in bone formation. In odontogenesis, Cbfa1 is not involved in the early signaling networks regulating tooth initiation and early morphogenesis but regulates key epithelial-mesenchymal interactions that control advancing morphogenesis and histodifferentiation of the epithelial enamel organ.  (+info)

An mtDNA analysis in ancient Basque populations: implications for haplogroup V as a marker for a major paleolithic expansion from southwestern europe. (7/1158)

mtDNA sequence variation was studied in 121 dental samples from four Basque prehistoric sites, by high-resolution RFLP analysis. The results of this study are corroborated by (1) parallel analysis of 92 bone samples, (2) the use of controls during extraction and amplification, and (3) typing by both positive and negative restriction of the linked sites that characterize each haplogroup. The absence of haplogroup V in the prehistoric samples analyzed conflicts with the hypothesis proposed by Torroni et al., in which haplogroup V is considered as an mtDNA marker for a major Paleolithic population expansion from southwestern Europe, occurring approximately 10,000-15,000 years before the present (YBP). Our samples from the Basque Country provide a valuable tool for checking the previous hypothesis, which is based on genetic data from present-day populations. In light of the available data, the most realistic scenario to explain the origin and distribution of haplogroup V suggests that the mutation defining that haplogroup (4577 NlaIII) appeared at a time when the effective population size was small enough to allow genetic drift to act-and that such drift is responsible for the heterogeneity observed in Basques, with regard to the frequency of haplogroup V (0%-20%). This is compatible with the attributed date for the origin of that mutation (10,000-15, 000 YBP), because during the postglacial period (the Mesolithic, approximately 11,000 YBP) there was a major demographic change in the Basque Country, which minimized the effect of genetic drift. This interpretation does not rely on migratory movements to explain the distribution of haplogroup V in present-day Indo-European populations.  (+info)

Expression of Wnt signalling pathway genes during tooth development. (8/1158)

We have carried out comparative in situ hybridisation analysis of six Wnt genes Wnts-3, -4, -5a, -6, -7b, and 10b together with Wnt receptor MFz6 and receptor agonist/antagonists MFrzb1 and Mfrp2 during murine odontogenesis from the earliest formation of the epithelial thickening to the early bell stage. Expression of Wnt-4, Wnt-6, and one Wnt receptor MFz6 was observed in the facial, oral and dental epithelium. Wnt10b was localised specifically to the presumptive dental epithelium. Wnts-3 and -7b were expressed in oral epithelium but showed no expression in the presumptive dental epithelium. Wnt-3 also showed no expression in the epithelial cells of the molar bud stage tooth germs, but showed restricted expression in the enamel knots which are signalling centres believed to be involved in regulating tooth shape. Wnts -6, -10b and MFz6 were also detected in the primary and secondary enamel knots. Wnt-5a and agonist/antagonists MFrzb1 and Mfrp2 were expressed in a graded proximo-distal (P-D) manner in mesenchymal cells during the early stages of tooth development with no overlying expression in the oral or dental epithelium. Wnt-5a and MFrzb1 show strong expression in the dental papilla mesenchyme.  (+info)

A Japanese group, led by cell biologist Takashi Tsuji of Tokyo University of Science in Noda, Chiba Prefecture, focused on tooth germs, the embryonic tissues that develop into teeth. After obtaining such germs from mouse embryos, they separated out two types of cells-epithelial cells and mesenchymal cells-and then recombined them into a new bioengineered tooth germ. The team then grew the bioengineered germs in a special culture for 5 to 7 days and transplanted them into the upper jaws of adult mice in the place of an extracted molar. New teeth poked through the gums after about 36 days and reached the proper size and alignment with opposing teeth for proper chewing after 49 days.. All indications are that the teeth function just like the real thing. They have the roots, inner pulp, and outer enamel of normal teeth and are just as hard, the team reports. Moreover, unlike dental implants, the regenerated teeth develop the periodontal ligaments that tie normal teeth to the supporting bone and the ...
Throughout your life, you will have two sets of teeth: primary (baby) teeth and secondary (permanent) teeth. At age 6-8 months, the primary teeth appear; all 20 are in place by age 3. Permanent teeth will begin to grow around age 6, and except for wisdom teeth, are all present between ages 12 and 14. The next teeth to grow in are the 12-year molars and finally the wisdom teeth. Wisdom teeth typically begin breaking through from age 17 and on. The total number of permanent teeth is 32, though few people have room for all 32 teeth. This is why wisdom teeth are usually removed.. Your front teeth are called incisors. The sharp fang-like teeth are canines. The next side teeth are referred to as pre-molars or bicuspids, and the back teeth are molars. Your permanent teeth are the ones you keep for life, so it is vital that they are brushed and flossed regularly and that periodic check-ups by a dentist are followed.. ...
Baby teeth hold space in the jaw for the adult teeth. If a baby tooth is lost too early, the teeth beside it may drift into the empty space. When its time for the adult teeth to come in, there may not be enough room for them. This may cause adult teeth to be crowded and crooked. Crooked teeth may be hard to keep clean.. If a baby tooth is lost too early, the teeth beside it may drift into the empty space.. If a childs baby teeth are healthy, it is more likely his adult teeth will be healthy too. Children who have decay in their baby teeth are more likely to have decay in their adult teeth.. Decayed and crooked teeth also can affect your childs self-esteem. Tooth decay is not only unhealthy, it also looks bad. If your child has tooth decay he may feel bad about his smile. On the other hand, a nice-looking smile can give your child confidence at school.. ...
We have studied the expression patterns of the newly isolated homeobox gene, Hox-8 by in situ hybridisation to sections of the developing heads of mouse embryos between E9 and E17.5, and compared them to Hox-7 expression patterns in adjacent sections. This paper concentrates on the interesting expression patterns of Hox-8 during initiation and development of the molar and incisor teeth. Hox-8 expression domains are present in the neural crest-derived mesenchyme beneath sites of future tooth formation, in a proximo-distal gradient. Tooth development is initiated in the oral epithelium which subsequently thickens in discrete sites and invaginates to form the dental lamina. Hox-8 expression in mouse oral epithelium is first evident at the sites of the dental placodes, suggesting a role in the specification of tooth position. Subsequently, in molar teeth, this patch of Hox-8 expressing epithelium becomes incorporated within the buccal aspect of the invaginating dental lamina to form part of the ...
Teeth are for life time and should not get loose even at 59 years of age. If gums are healthy, then teeth will not get loose even at advanced age. Teeth can get loose due to trauma to tooth or because of deposits in relation to teeth or can get loose because of some systemic conditions like diabetes. If teeth are mobile because of gum infection, then dental cleaning can be done to make teeth firm. Gum surgeries may also be required. Patient should maintain good oral hygiene in this condition and should brush and floss his teeth regularly to avoid deposits on teeth which can further lead to teeth loosening. If teeth are loose because of trauma, then splinting or capping can be given to the patient. If there is root infection present in relation to loose tooth, then root canal therapy will also be done. If systemic condition is reason for loosening of tooth, then systemic condition should be brought under control. If teeth are very loose, then you can get the teeth pulled out. If teeth are pulled ...

To fully understand the purpose of a root canal treatment, it helps to get a good grasp of the tooths anatomy. The first layer of the tooth, known as the enamel, encases another layer called the dentin, which contains soft tissues called the pulp. The tooth pulp comprises the nerves, blood vessels and connective tissues, and plays an important role during the eruption in developing the surrounding hard layers of the tooth.. The tooth pulp runs from the tooth crown to the tip of the root. It is important while the tooth is still growing. However, after the tooth fully forms, it can survive independent of the pulp.. A person will need a root canal treatment if the pulp chamber of the tooth becomes infected or inflamed. This may be due to severe tooth decay, tooth cracking and other forms of tooth damages. Without treatment, pulp infection can cause severe pain or cause a tooth abscess, which often necessitates tooth extraction.. There are visible signs that a person needs to undergo root canal ...
Many people who have teeth grinding remain unaware of it until additional health problems arise. Teeth grinding, also known as Bruxism is the grinding, clenching, or gnashing of the teeth, whether awake or sleeping. Those who grind their teeth while sleeping usually dont know that they do.. Bruxism is a problem because teeth grinding causes tooth enamel to wear down. Your teeth should only come into contact when youre chewing or swallowing. When tooth enamel wears down, the inner part of your tooth becomes exposed. Additional dental problems can occur because these delicate parts of your tooth are no longer protected by the enamel.. Some common symptoms of Teeth Grinding include:. · Jaw pain. · Sore facial muscles. · Waking up with a headache. · Tight jaw muscles. · Trouble opening your mouth wide. · Broken dental fillings. · Damage to the teeth. If youre worried that you might have Bruxism, you can ask a dentist to check. To determine whether or not you suffer from teeth grinding, ...

These are modern new age aligners which are transparent and can correct a series of tooth problems such as cross bites, under bites, overbites, irregularities of teeth, spacious teeth s, overlapping teeth s, protruding teeth s, crowded teeth and so on ...
Losing a tooth is a big moment for any child. As a parent, you want to be able to make those moments memorable. When do kids lose their teeth? According to the Mayo Clinic, children begin to lose their baby or primary teeth around the age of six and may continue to lose their teeth up to the age of 13. While this range will vary from child to child, girls tend to lose their teeth sooner than boys. The following are some tips to help you and your child prepare for the first loss of a baby tooth.. Start the Conversation Early. A common question from many children is, Why is my tooth falling out? Baby teeth loosen as their roots begin to dissolve. The time it takes for one tooth to fall out after it has become loose is generally a few months. As the adult tooth begins to grow, the baby tooth becomes increasingly looser. Teeth tend to fall out in the same order in which they came in. The bottom two front teeth generally fall out first followed by the top two front teeth. Try to keep the ...
The present invention relates to a recording medium a method and an apparatus for generating virtual teeth and recording media storing a program performing the method. According to an embodiment of the present invention, a method for generating virtual teeth includes (a) acquiring a tooth image having three-dimensional information from teeth including a damaged tooth; (b) determining an image of a virtual tooth to be inserted into a position of the damaged tooth in a tooth image library having predetermined three-dimensional information and inserting the determined virtual tooth image into the acquired tooth image; and (c) modifying the virtual tooth image by considering tooth images positioned at upper and lower sides or right and left sides of the virtual tooth image. According to the embodiment of the present invention, it is possible to produce a prosthesis most suitable for the state of patients teeth only once and an operator can minimize post-processing of the produced prosthesis. Further,
Here we have used previously described methods to bioengineer teeth from human dental stem cells (hDSC). We we were able to demonstrate that dissociated hDSC-seeded polymer constructs can form bioengineered teeth that are morphologically similar to natural human teeth at both gross and microscopic levels. We anticipate that further modifications of this approach will eventually result in reliable methods to bioengineer replacement teeth in humans.
1 - The enamel and dentin are thinner in baby teeth, and the pulp is bigger relative to the rest of the tooth. This means that if your child gets a cavity, it will travel much faster to the nerve of the tooth. This is one more reason why its important to take your child to the dentist before they turn one year old and get routine checkups thereafter.. Not sure what enamel, dentin, and pulp are? Read my previous article about the anatomy of a tooth.. 2 - Permanent teeth are more yellow than baby teeth. Take a quick look at the picture above and youll see that the six permanent teeth that are visible dont look nearly as white as the other baby teeth.. 3 - Baby teeth have shorter roots - because of this they arent anchored as well into the bone and may fall out more easily if your child falls on a hard step or hits their mouth on the coffee table. The shorter roots also give the permanent teeth more room to develop underneath the baby teeth and make it easier to dissolve the roots of the baby ...
Tooth agenesis is one of predominant developmental anomalies in humans, usually affecting the permanent dentition generated by sequential tooth formation, and in most cases caused by mutations perturbing epithelial Wnt/β-catenin signaling. Also loss-of-function mutations in the Wnt feedback inhibitor AXIN2 lead to human tooth agenesis. We investigated the functions of Wnt/β-catenin signaling during sequential formation of molar teeth using mouse models. Continuous initiation of new teeth, observed after genetic activation of Wnt/β-catenin signaling in the oral epithelium, was accompanied by enhanced expression of Wnt antagonists and a downregulation of Wnt/β-catenin signaling in the dental mesenchyme. Genetic and pharmacological activation of mesenchymal Wnt/β-catenin signaling negatively regulated sequential tooth formation, an effect partly mediated by Bmp4. Runx2, a gene whose loss-of-function mutations result in sequential formation of supernumerary teeth in the human cleidocranial ...

Although your teeth feel as if theyre rigidly set in the jawbone, theyre actually capable of movement. In fact, dynamic tooth movement is an essential mechanism in good dental function - it allows your teeth to adapt to changes brought on by age and other factors.. The periodontal ligament is a key component in this mechanism. This elastic tissue actually holds the teeth to the bone through tiny fibers that attach to the tooth root on one side of the ligament and to the jawbone on the other. The teeth move within the ligament to maintain contact with both adjacent and opposing teeth in response to changes like the normal wear that occurs due to aging.. This is a primary reason why a missing tooth should be replaced by an artificial one as soon as possible. Because of the tendency just described, teeth next to the space left by the missing tooth will begin to move (or drift) into the space at an accelerated rate. The end result is teeth out of their normal position and range, which could ...
1. State the objective and introduce the lesson on brushing and flossing. 2. Define Cavity 3. Define Plaque as buildup on our teeth. 4. Many people think being unhealthy means being overweight, having an illness...not as having unhealthy teeth. Teeth are a very important part of your body. Your teeth are designed to last you a lifetime, with proper care they can! 5. Basic care of teeth includes brushing your teeth daily, at least twice a day, and after meals if possible. Brushing your teeth helps to remove bacteria and plaque from your teeth, gums, and mouth. 6. Flossing is just as important as brushing. Flossing cleans and removes food particles which become lodged in between your teeth. It also removes plaque build up. You should be sure to floss between each tooth and dont skip around. Dont floss all your teeth, only the ones you want to keep. 7. Does anyone know what Fluoride is? Fluoride has been identified as the most important factor in preventing tooth decay. Fluoride in the water ...
Whatever the reason, many folks are turned away from the idea of braces. They pin their hopes on the imagined chance that their childrens teeth will gradually and naturally straight out.. Is there any basis for this reasoning?. Normal Tooth Spacing is Age-Dependent. As the adult take over the places baby teeth once rested in, things get a little messy!. Permanent teeth grow in as the jaw expands. Some adult teeth come in before the baby teeth are out of the way. All of this change leads to some overlapping and big gaps.. For instance, the bottom front teeth often erupt towards the tongue. This can be a little alarming, but these teeth actually should straighten out on their own.. If most teeth can naturally even out, at what point are braces necessary?. Early Ortho Evaluations Save Smiles!. Its a good idea for kids to visit an orthodontist by around the age of 7. This is a great time for the dentist to see how tooth development is progressing and anticipate how severe problems can be. At this ...
More than 5 million teeth are knocked out in the United States every year. If you find yourself or your child in this situation, dont panic. With the proper steps taken the tooth can be saved and as good as new in a few hours.. The first step you should take if your tooth is knocked-out is to retrieve the tooth by the crown, the part that is exposed above the gums in the mouth. Try not to touch any attached tissue that is normally below the gums. Rinse the tooth if necessary, but do not use soap, scrub, or dry the tooth. If possible try to put the tooth back in the socket, but never force it. If the tooth wont rest comfortably in the socket then placing the tooth between your cheek and gums is the next best option. Another option is to place the tooth in a glass of milk. It is important that the tooth stays moist, although water is not a good option. No matter the case it is important to see your dentist at Dental365 as soon as possible. Teeth that have been knocked out have a higher chance of ...
15 years ago when I was 8, I lost one of my front teeth in an accident. As a result, my other front tooth moved over and is now smack dab in the middle. My other front teeth moved with it; for the most part, my top teeth are straight. I cannot get over the fact that I have one front tooth. There is no longer a gap, but since my two front teeth were longer than the rest of my teeth, my now one front tooth hangs lower and it makes me extremely self conscious. My question is: Are there veneers that can cover my front tooth (teeth) that can make it appear as though I have 2 front teeth? Or would I need a crown? Any information would be much appreciated. I feel like Im the only person in the world with 1 front tooth who doesnt have a gap and has a straight smile. Thank you in advance ...
Crooked teeth affect not only your smile but also your dental health. This is because crooked teeth make dental cleaning difficult and hence increase your risk of tooth cavities and gum disease. Even a single crooked tooth throws your entire smile off balance.. There is a range of cosmetic dentistry options your dentist might recommend for straightening crooked teeth. In children, pediatric dentists might suggest that they reach a certain age before undergoing treatment. But the ideal choice depends on the severity of the problem and your desired results. Here are some of the most efficient dental options for crooked teeth.. Teeth Bonding. In this cosmetic dental procedure, a tooth-colored resin applied to your teeth reshapes them. Tooth bonding also lightens stained teeth and closes minor gaps. This minimally invasive procedure involves no anesthesia, and needles can be completed in a single visit. Tooth bonding is the ideal solution for slightly crooked teeth.. Porcelain Veneers. These are the ...
The answer of this qs is very long for you.A dead tooth often becomes dark or turns black because of the rotting material inside. There may be no symptoms at all and someone can walk around with a dead tooth for years before becoming aware of it.. The dead tooth often becomes obvious when something else happens that runs the patient`s immune system down, such as a bad cold, pneumonia or a severe viral infection.A dead tooth can be caused by tooth decay, trauma, deep dental fillings, gum disease, or in some cases, tumors. Once a tooth dies it will never return to life again. The contents of the tooth liquefy and putrefy and seriously endanger the owner`s health.You should go see a dentist to check if your tooth really is dead and seek treatment for it.There are only two treatment options for a dead tooth, tooth extraction or root canal therapy. There are no good other choices! Of course, you could keep the dead tooth in your head but remember that the brain is only about three inches away.A dead ...
Most childrens permanent teeth erupt on a fairly predictable schedule. Sometimes, though, one or more teeth might not develop as they should - or at all.. These absent teeth pose functional problems for chewing and hygiene, which can affect long-term dental health. But they can also have a disruptive effect on an otherwise attractive smile if the missing teeth are the upper lateral incisors in the most visible part of the smile.. You normally find this pair of teeth on either side of the upper central incisors (the two front-most teeth). On the other side of the lateral incisors are the canine or eye teeth, known for their pointed appearance. Without the lateral incisors, the canines tend to drift into the space next to the central incisors. This can produce an odd appearance even a layperson will notice: only four teeth where there should be six!. Its possible to correct this abnormality, but it will take time and expense.

A tooth thats been chipped doesnt mean its no longer healthy. The same, unfortunately, cant be said about the attractiveness of your smile, especially if its one of your front teeth. A chipped tooth can be quite noticeable and make you self-conscious.. The good news is a chipped tooth can be restored cosmetically to look just as normal and attractive as your other teeth. Depending on the application there are two different materials we commonly use: porcelains, a type of oven-fired ceramic most often found in veneers or crowns; or composite resins, a mixture of glass and plastic substances we apply in liquid form that hardens in built-up layers on the tooths surface to ultimately resemble normal tooth shape and color.. So, which of these two materials is the best option for your tooth? That depends on the extent and location of the tooth damage. Composite resins are most often used for mild to moderate chipping or breaks in the enamel (and somewhat for the underlying dentin) or decayed ...
Perhaps you have noticed some people have whiter teeth than others, and while this is partially genetic its also due to the thickness of the tooth enamel. A thicker layer of tooth enamel will prevent more of the natural colour of the tooth from shining through. The natural shade of your teeth is contained in the dentine layer just underneath the enamel. Younger people are more likely to have a thicker layer of enamel, and this not only gives them whiter teeth, but also helps prevent damage to the dentine. Anyone who is interested in teeth whitening in London may also be interested in how they can help lessen damage to the tooth enamel. So exactly why does tooth enamel become thinner, and what can be done to at least help lessen this effect?. Demineralisation Damages Tooth Enamel. Demineralisation is something that takes place every day, as it occurs every time we eat or drink something, especially foods containing carbohydrates and sugars. This is because they are the perfect food for plaque ...
TY - JOUR. T1 - Cell cycle of the enamel knot during tooth morphogenesis. AU - Jung, Seo Yoon. AU - Green, David William. AU - Jung, Han Sung. AU - Kim, Eun Jung. N1 - Funding Information: Acknowledgements We are grateful to Chengri Li for helping experiments. This study was supported by the Yonsei University College of Dentistry (6-2016-0021).. PY - 2018/6/1. Y1 - 2018/6/1. N2 - Enamel knot (EK) is known to be a central organ in tooth development, especially for cusp patterning. To trace the exact position and movement among the inner dental epithelium (IDE) and EK cells, and to monitor the relationship between the EK and cusp patterning, it is essential that we understand the cell cycle status of the EK in early stages of tooth development. In this study, thymidine analogous (IdU, BrdU) staining was used to evaluate the cell cycle phase of the primary EK at the early casp stage (E13.0) and the gerbil embryo (E19) in a developing mouse embryo. The centerpiece of this study was to describe the ...
Teeth crowding is a difficult bite problem (malocclusion) that often involves the entire jaw structure to be evaluated. Normally occurring when the jaw doesnt have adequate space for normal tooth eruption, teeth coming in later put pressure on other teeth, causing them to develop improperly.. Crowding also makes it difficult to realign teeth with braces because theres simply not enough room for sufficient movement to take place. The solution may then be to consider the removal of some of the teeth to create enough space for orthodontic treatment.. Not just any tooth can be removed, however - we must first conduct a careful analysis to determine which can be removed to facilitate optimum movement of the remaining teeth without disrupting normal mouth function or affecting appearance. The teeth most frequently removed for this purpose are the bicuspids, located between the cuspids or eyeteeth (which are positioned directly under the eyes) and the molars, the largest teeth in the back of the ...
A system and method for modeling of complete tooth, including root and crown, of a patient to facilitate orthodontic treatment are provided, wherein generic tooth modeling is combined with tooth crown modeling for a patient to yield complete tooth modeling. A generic tooth 3D model for a particular tooth is morphed with a 3D model of a patients crown for the corresponding tooth to yield a complete 3D model for that tooth. Modeling techniques can be conducted with computer-based systems, such as systems configured for storing patient data and generic tooth data, morphing such data and/or facilitating additional orthodontic treatment applications, through the use of one or more algorithms. Adjustment of the complete tooth model for the tooth can be provided through additional patient information, such as X-ray imaging, to address variations in root shape between a generic root and an actual root shape for a patient.
Importance of deciduous teeth. Your childs baby or deciduous it is important to save in order to maintain the space for their adult teeth. Although baby teeth will be lost gradually until children turn 12, they are important to maintain the arch integrity and to guide the eruption of the permanent successors. Baby teeth help to keep all of the teeth in alignment so that the permanent tooth will grow in the correct position. If they are removed, teeth will often shift, leading to crowding and future need for braces. The innermost part of the tooth is called pulp, protected by strong outer layers namely enamel and dentine. It contains nerves as well as the blood vessels which keep it alive and healthy. A deep cavity in your childs baby tooth may go into the pulp of the tooth which is still alive thus causing a lot of discomfort and pain to the child.. In this case, a pulpotomy is recommended to save the tooth by preventing nerve and root death. During this pulpotomy procedure only the part ...
So, when the teeth you have specified the need to spit then should go to the specialist for consultation and if possible should do the same Implant and tooth 1 time will save a lot of time, cost and benefit oral health, and appearance.

Despite all of the improvements that have come about in the world of dentistry, there are still lots of people who end up suffering from tooth loss. A lot of these individuals will lost their teeth from gingivitis (gum disease), tooth decay or injury to the teeth or gums. For quite a long time, the only available options in terms of treatment would be dentures or bridges. Today, there are more and more people who are taking advantage of the advances that have been made with dental implants.. A dental implant is basically a replacement tooth root. The implant will offer a strong foundation for permanent (fixed) or replacement teeth that are removable and made to match up with your natural teeth. When implants are fitted and put in place, they can blend right in and make for a strong addition to the mouth. Once the implant is in, it is fully functional and eating, drinking and all activities can be done without issue.. With dental implants, you are going to get improved appearance, improved speech ...
Scientists are developing the technology to enable teeth to regrow the crystals that make up dentin and enamel. The technology will eventually phase out fillings and drillings completely.. The goal - estimated to be at least 10 years away - is to spot tooth decay early enough that they then get the teeth to grow healthy tooth-matter over the bad spots.. The scientists are beginning to find just the right solutions of chemicals to rebuild decayed teeth, rather than merely patching their holes. What were hoping to have happen is to catch [decaying teeth] early and remineralise them, said Sally Marshall, a professor at the University of California at San Francisco. By putting a layer of the solution on individual test teeth, Marshall has already been able to remineralise some parts of the teeth. This ability to use some of the bodys own building materials for oral repair would be a boon - but scientists are discovering that dentin, in particular, is a remarkably complex structure.. Marshalls ...
You can have a gold teeth or teeth of any other material u like in replacement of the teeth u lost. The better option is of a tooth that matches the color of your teeth. The cost for the entire process depends upon the value of teeth u like to have in the mouth. A cheaper tooth can be of 15 dollars and an expensive one has no limit. But if you order a tooth which is inexpensive that will later cause infection in your mouth and there are chances that you might loose some other teeth because of that artificial tooth in your mouth ...
A tooth (plural teeth) is a hard, calcified structure found in the jaws (or mouths) of many vertebrates and used to break down food. Some animals, particularly carnivores, also use teeth for hunting or for defensive purposes. The roots of teeth are covered by gums. Teeth are not made of bone, but rather of multiple tissues of varying density and hardness. The cellular tissues that ultimately become teeth originate from the embryonic germ layer, the ectoderm. The general structure of teeth is similar across the vertebrates, although there is considerable variation in their form and position. The teeth of mammals have deep roots, and this pattern is also found in some fish, and in crocodilians. In most teleost fish, however, the teeth are attached to the outer surface of the bone, while in lizards they are attached to the inner surface of the jaw by one side. In cartilaginous fish, such as sharks, the teeth are attached by tough ligaments to the hoops of cartilage that form the jaw. Some animals ...
Your teeth are precious. Once your permanent teeth come in, they need to last you a lifetime. Extensive tooth decay can lead to dental caries and the need for fillings, crowns, bridges, and dentures.. While these fixes can go a long way toward maintaining your quality of life, they cannot compare to your natural teeth. Getting braces is no excuse to let up on your thorough oral health routine: You need to take good care of your teeth before, during, and after braces to benefit completely from the gains you get from newly straightened teeth.. Why You Should Maintain Good Oral Health for Life. Begin a complete oral health regimen as early as possible in life, and maintain this routine throughout your life. Keeping your (or your childs baby) teeth clean establishes a routine. It preserves healthy baby teeth whose function is to save space for the permanent teeth when they are ready to come in. Care of your permanent teeth helps preserve the enamel and prevent decay.. Take Special Care with ...
Poor development of both milk and permanent teeth may be associated with poor oral hygiene,when the teeth are attacked by caries, and their further development and growth may be severely damaged. If the diet (or toothpaste) man get enough calcium and fluoride, and generally all substances that tooth for their development needs, the development of tooth again altered. Poor development can result from the failure of embryonic foundations teeth, tooth not develop at all -aplasie or insufficiently -hypoplasie may be in a different place than it should be, is rotated or tilted. Hereditary disease which mainly reflects the poor development of teeth is amelogenesis imperfect. A specific problem may be defective teeth in the context of congenital syphilis - barrel-shaped teeth. Such diseases are numerous. Above all, regular visits to the dentist who reveal any pathological changes.
If you take a look at your dogs teeth you can spot if there is a broken tooth, as this is clearly visible. However, you may mistake a broken tooth for a decayed one that has a brown spot on it, so it is recommended to visit the vet. It is important to determine if the pulp of the tooth has been exposed. When the pulp of the tooth is exposed, there will be a small dark spot (a hole) exposed on the surface of the tooth. This will require treatment, as the exposure of pulp and the nerves will cause a lot of pain to the dog. The nerves will eventually die (in up to 2 months), but the hole will allow bacteria to enter and cause infections. If the pulp of the tooth is not exposed, vets dont recommend any treatment. There are 2 options of treatment when the pulp is exposed: tooth extraction or tooth repair. Tooth repair will involve the extraction of the nerve (root canal therapy) and then the tooth will be restored. Some vets may also recommend the placement of dental caps to protect the devitalized ...

The initial information for patterning of early tooth development resides in the epithelium. Later, this is shifted to the mesenchyme. The process is governed by multiple epithelial- mesenchymal interactions, Integrins are cell surface receptors for extracellular matrix components. Expression of the beta(5) integrin subunit alternates between epithelium and mesenchyme during early tooth development (Yamada et al, [1994] Int, J. Dev. Biol, 38: 553-556), By immunofluorescence and in situ hybridization we show here a remarkably similar oscillating expression pattern of the alpha(v) integrin subunit. This subunit is known to associate with beta(5), and we therefore suggest that integrin alpha(v) beta(5) is involved in epithelial-mesenchymal interactions during tooth development, We also demonstrate that the developing tooth epithelium expresses the alpha(6), beta(1) and beta(4) subunits. The laminin receptors alpha(6) beta(1) and alpha(6) beta(4) may thus in part mediate the effect of basement ...
The eruption of teeth usually starts from 6 months after birth. The first set - which are called the milk teeth / baby teeth / deciduous teeth or primary teeth - and consist of 20 teeth (10 in the maxilla and 10 in the mandible), all rise till the age of 2 years. From then on these teeth start to fall and give their spots to more mature biters called Secondary teeth or Permanent teeth. Permanent teeth are 28 (14 in the maxilla and 14 in the mandible ...
Posted on 05/18/2013 2:08:28 PM PDT by LibWhacker. An international team of scientists led by Prof Cheng-Ming Chuong from the University of Southern California has discovered unique cellular and molecular mechanisms behind tooth renewal in American alligators (Alligator mississippiensis).. Their findings, published in the Proceedings of the National Academy of Sciences, pave the way for tooth regeneration in people. Humans naturally only have two sets of teeth baby teeth and adult teeth. Ultimately, we want to identify stem cells that can be used as a resource to stimulate tooth renewal in adult humans who have lost teeth. But, to do that, we must first understand how they renew in other animals and why they stop in people, Prof Chuong said. Whereas most vertebrates can replace teeth throughout their lives, human teeth are naturally replaced only once, despite the lingering presence of a band of epithelial tissue called the dental lamina, which is crucial to tooth development. Because alligators ...

However, the expression patterns and functions of GSLs during tooth development remain unclear. In this study, we identified strong expressions of GM3 and LacCer in dental epithelium, which give rise to differentiation into enamel-secreting ameloblasts. Exogenous GM3 and LacCer in dental epithelial cells induced the expression of ameloblastin (Ambn), while it was also ...
You were born without any teeth. So was I. So is everybody.. Do you know when your first tooth popped out? The first tooth, usually the lower front tooth, appears at the age of 6-8 months. Though it could be a little later or earlier. Some rare times, babies are born with teeth already in their mouth. These are called Natal teeth. Were you a natal teeth baby?. By the time you were three, you probably had all you milk teeth - 20 teeth in all. 10 in upper jaw (maxilla) and 10 in lower jaw (mandible). Milk teeth are the first set of teeth that grow in our mouth, and they are not permanent. They are also called deciduous teeth, primary teeth or fall teeth since they eventually fall.. There comes a day, when while munching on a firm fruit you realize your tooth is wobbly. You are around six years old and your milk teeth start falling out. They give way to stronger permanent teeth that are going to stay with you for life. Over the years, 32 Permanent teeth adjust themselves in our mouth. 16 are ...
So, how do babys teeth grow ? The baby teeth actually starts growing during the 6th week in the mothers uterus. These baby teeth growth starts with the Bell shape tooth germ. This Bell shape structure seen is actually the enamel organ, which will eventually grow into a baby teeth. As you can see the enamel organ or tooth germ contains numerous cells. These cells will continue to grow and differentiate into different and more advance cells to form the tooth. The outer and inner enamel organ eventually forms the outer casing of the tooth called the enamel layer. Where else the dental papilla cells will form the inner section of the tooth known as the pulp chamber. The permanent tooth bud will continue to grow into the permanent teeth after the baby tooth eruption is completed in the mouth.. ...
Tooth enamel formation. Coloured scanning electron micrograph (SEM) of a freeze-fractured section through a tooth, showing the enamel-forming cell layer (green). This epithelium comprises a single layer of columnar cells called ameloblasts. The fracture plane passes up into the tooth from the enamel surface (orange, bottom left). The ameloblast layer has detached from the enamel in which it is normally embedded. Enamel is a hard ceramic layer that covers and protects the teeth. The other end of the ameloblasts originate in the internal tooth tissue (brown, across top). Magnification unknown. - Stock Image P486/0080

I have a tooth that looks horrible. It looks like it belongs in somethings mouth, not in a persons mouth. The tooth is thin and pointy and the shape and color are even different from my other teeth. The tooth is on the left side but if I smile even slightly wide people notice it. I have heard a few thoughtless people joke about it. I want to do something about it now that I have better dental insurance. Can this tooth be pulled and replaced with a dental implant? Ivy. Ivy - If your tooth is healthy and structurally sound, it doesnt need to be replaced with a dental implant. Dental implants replace missing teeth or teeth that cannot otherwise be saved, but nothing is as effective as keeping your natural teeth..

It is prominent to close your gap because a tooth gap can cause tooth misalignment. A large tooth gap between the front teeth could leave insufficient room for the ones next to the front teeth. This may cause tooth displacement and problems with the bite. Someone else suspect is self-consciousness. Some people may feel embarrassed, and reluctant to smile with parted lips.. Gapped front teeth in the upper jaw close by themselves in many cases. Generally, a babys teeth start to erupt between six and nine months. At this early age, the front teeth could be gapped and the maxillary labial fraenum attached low to the gum. By the time the child reaches its first birthday, the fraenum has probably shortened, and the eruption of more teeth has complete any gaps. If the adult front teeth are gapped, the eruption of molars helps to crowd the front teeth together. About one in 10 children have gapped adult front teeth that dont close by themselves.. Luckily, there is a straightforward explication to ...

First, remain calm. If your child has knocked a tooth out, find the tooth, trying to avoid touching the root of the tooth. If it is a baby tooth, DO NOT place it back in the mouth, but visit the dentist to ensure no other trauma has occurred (placing a baby tooth back in can cause long-term damage to the permanent tooth bud). If a permanent tooth is knocked out, rinse with cool water only (not scrubbing) and gently try to reinsert it into the socket where the tooth was. If that is not possible for whatever reason, place the tooth in a glass of cold milk and visit the pediatric dentist immediately (the faster you act the better chances of saving the tooth). If your childs tooth was not knocked out, it is still important to visit the pediatric dentist to fully assess all injuries, including providing antibiotics where necessary. Any fractured pieces of teeth should also be saved and brought to the office. If your child experienced a blow to the head or jaw, he/she needs immediate medical ...
When Should You Go For Root Canal Therapy. Lets know about the scenarios which make it essential to pick for this teeth saving treatment.. Rot Begins Troubling The Tooth Pulp. The soft middle of your tooth or the pulp constitutes nerves and sensitive arteries, which may endure slow decay. In reality, the more your tooth has cavities the higher are its opportunities to change the pulp. At the worst, improper control of pulp ailment could compel one to lose your teeth. Preserving proper dental hygiene like routine tooth cleaning and flossing could not be ineffective in this respect. But youre determined to keep your tooth, and if the state has not gone corrigible, Root Canal Therapy is probably the last resort.. Abscessed Tooth. This debilitating illness lasts largely, or between the gingiva and the tooth at the root of the tooth. It originates in the interior chamber or the pulp chamber of the tooth. As an indicator of the abscess, the tooth enables the pulp chamber to be occupied by the ...
When we are growing up we get two sets of teeth. Your baby teeth that start to grow in sometime around the age of 6-9 months, and your adult teeth. The adult teeth will start to come in around the age of 6-years, and will stay with you for the rest of your life if you take good care of them. In the past, even as long ago as just 100-years, it was very common for people to lose some of their adult teeth. This was before we had toothpaste and tooth brush, or good dental care.. Because of these missing teeth the human body tried to help us out by growing wisdom teeth. These teeth are additional molars that start to grow in any time between the ages of 17-24 depending on the person. With better dental health that has come about in the last 100-years or so, most adults dont have to worry about any missing teeth until they are well into their 20s or 30s and so wisdom teeth can sometimes be more of a problem than a help.. Not everyone will get wisdom teeth.. Some people do not develop wisdom ...
At Doha Dental we perform procedures such as a root canal in Doha Qatar for patients who have damaged teeth and tooth roots. If tooth decay has reached a level where the pulp of the tooth has been damaged, root canal therapy is the best way to save it from the need for extraction. A root canal helps to fix the damaged pulp inside a tooth and then clean it before capping it off for protection.. Symptoms that a root canal is needed are inflamed and red gums, tooth pain, infection or infection that leads to abscess. The pulp is the living tissue that keeps a tooth alive, and it can become inflamed or infected for various reasons. There are many different causes of infection, but usually it is a result of tooth decay. Sometimes repetitive dental procedures or tooth damage can also harm the tooth and cause the need for a root canal in Doha Qatar. Cracks, chips and fractures can all contribute to damaged pulp inside a tooth. Gum disease can also be a culprit. Inside the tooth, the pulp that is damaged ...

Injuries and accidents. Trips, falls or sports injuries can cause the teeth to become damaged. If the teeth are not salvageable they will usually be extracted.. Periodontal disease. This condition refers to severe cases of gum disease. Periodontal disease affects the tooth sockets and tissue in the gum. This tissue is what holds the teeth in place. If it becomes damaged the teeth may become loose.. Overcrowding. The teeth are said to be crowded when there is not enough space in the mouth to accommodate them all in the correct position. Many people suffer from this problem. It is normally the result of having a smaller jaw than normal. It is also caused when people have lost their primary set of teeth at an earlier age than usual and so suffer from crowded teeth.. Wisdom teeth. Many people do not have enough room in their mouth for their wisdom teeth to develop properly and this can cause them problems. If this is found to be the case then the wisdom teeth will usually be removed.. Are there ...
Odontogenesis is governed by a complex network of intercellular signaling events between the dental epithelium and mesenchyme. This network leads to the progressive determination of tooth shape, and to the differentiation of these tissues into enamel-producing ameloblasts and dentin-producing odontoblasts respectively. Among the main signaling pathways involved in the regulation of tooth development, Bone Morphogenetic Protein (BMP), Sonic hedgehog (Shh) and Wingless-type MMTV integration site (Wnt) pathways have been reported to play significant roles. Recently, the phenotype of mice deficient in Epiprofin/Sp6 (Epfn) has been found to present striking dental abnormalities, including a complete lack of differentiated ameloblasts and consequently no enamel, highly altered molar cusp patterns and the formation of multiple supernumerary teeth. In this article, we review the interaction of Epfn with the BMP, Shh and Wnt pathways in the regulation of tooth development, based on the data obtained from the
There are a number of different reasons a tooth may need to be extracted (pulled). Some teeth are removed because they are severely decayed; others may have advanced periodontal disease, or have broken in a way that cannot be repaired. Other teeth may need to be extracted because they are poorly positioned in the mouth (such as impacted wisdom teeth), or in preparation for orthodontic treatment. In some cases, the tooth is simply not repairable, or may be decayed below the gum line, or has lost too much bone due to gum disease. Sometimes, its a matter of health in the case of infections, cysts, or wisdom teeth. And teeth are frequently removed to create the space necessary to allow for other teeth to grow.. Dr. Hooper is very skilled at teeth extractions but understand the removal of a single tooth can lead to problems related to your chewing ability, problems with your jaw joint, and shifting teeth, which can have a major impact on your dental health. So they will also discuss with you ...
When these teeth come through the gums during early adulthood, the other teeth are well-established in the gums and jaw. Since these teeth are well-established, having any extra teeth emerge so late in life may lead to unwanted movement of the teeth. Crowding is the most common spacing issue associated with wisdom teeth. It affects tooth placement as well as your comfort. Tooth movement contributes to a headache that is an issue that usually affects patients with wisdom teeth emerging. Having these teeth removed can improve the frequency of headaches since teeth no longer have pressure on them from the third molars.. ...
Tooth discoloration (also termed tooth staining) is abnormal tooth color, hue or translucency. External discoloration is accumulation of stains on the tooth surface. Internal discoloration is due to absorption of pigment particles into tooth structure. Sometimes there are several different co-existent factors responsible for discoloration. The appearance and perception of a tooth is the result of a complex interaction of factors such as lighting conditions, translucency, opacity, light scattering, gloss and the human eye and brain. Of these, the intrinsic pigmentation of a tooth is the most influential, which in turn is determined by genetic and natural factors. Light hitting a tooth undergoes reflection, absorption and transmission by varying degrees in each tissue layer of the tooth substance. Reflected light detected by the human eye determines the perceived appearance of a tooth. Teeth have a thin enamel layer on the outer surface. The enamel layer is whiter and semitransparent, and ...
Countless individuals grind their teeth, either in their sleep or as a habit. However, this may not just wear you down but also your enamel. Bruxism, the medical term for tooth grinding, affects one in every four dental patients and the figures are only rising. Dr. Barber at Alliance Family Dental in Fayetteville, NC would like you to be aware of the dangers of grinding your teeth.. Causes of Bruxism. The reasons why people grind their teeth are varied, with cases being brought on due to emotional stress as well as a physical reaction, to loss of sleep. Some people grind their teeth while they are unconscious and in the middle of sleep, while others do so throughout the day while they are awake.. Excessive teeth grinding can result in permanent enamel damage in the form of fractured teeth, teeth sensitivity and tooth decay. Other know consequences of teeth grinding include receding gums, premature tooth loss and inflammation of the gums.. Signs of Bruxism. Especially for people who do arent ...

Have you noticed a crooked tooth? Or a pain in a tooth? Or maybe sore gums? You may be ignoring these small issues in your mouth, but you shouldnt. This is actually your mouths way of telling you that something could be wrong. So what are your teeth telling you? Here are some of the most common dental complaints and what they mean.. Sharp tooth pain - If you experience a sharp, sudden pain in your tooth while biting down, you may have a cavity or some form of tooth decay. When holes get deep in your tooth, it will cause sensitivity. If the pain occurs only once, its probably nothing to worry about. But if it is consistent, definitely see your dentist.. Achy tooth pain - An achy pain may be nothing if it is only lasting a day or two, but pain that lasts for more than a week could be a sign that youre grinding or clenching teeth.. Yellow or stained teeth - Stained or yellow teeth are almost never a sign of serious dental concerns. Stains usually develop from foods or drinks that you are eating ...
The average adult has 32 teeth in their mouth; 16 in the upper jaw and 16 in the lower jaw. Wisdom teeth, or third molars, are teeth in the back of the mouth, and are often the last teeth to grow and develop in the mouth. Wisdom teeth can erupt in proper alignment, and with healthy gum tissue, your referring dentist may feel comfortable leaving the teeth intact. However, many times there is not enough room in the jaw to accommodate these teeth to erupt into the mouth with proper alignment. Often, when these teeth do erupt into the mouth, they are not in a position to allow for adequate hygiene, or they may cause mal-alignment of neighboring teeth. Poorly positioned wisdom teeth, along with oral bacteria, can promote bone loss, cyst formation, infection, and gum disease of adjacent teeth. ...
Reimplantation refers to the insertion and temporary fixation of a completely or partially avulsed (knocked out) tooth due to traumatic injury. There is no realistic way to prevent the avulsion of teeth as it usually occurs due to an accident. However, wearing a mouth guard during sports activities usually helps reduce risk.. The most common teeth to be knocked out are the upper front permanent teeth, although primary teeth can also be avulsed. Reimplantation of primary teeth is not usually performed as these teeth are naturally replaced by permanent teeth later in life.. The success of reimplantation depends on the amount of time the tooth is out of the socket. If reimplantation can be performed within one hour of the tooth being knocked out, success rates are much higher.. ...
Unlike most teeth, which erupt in childhood, wisdom teeth (also known as third molars) generally appear between the ages of 17 and 25. Linguists believe these teeth received the nickname of wisdom teeth because they appear later in life than other teeth - at an age when a person has matured into a young adult.. So why do we have wisdom teeth? Anthropologists point to our ancient ancestors for the explanation.. Ancient civilizations had very different diets than we do today. Instead of driving to the grocery store, our early ancestors hunted and gathered whatever food they came across in nature.. Snacking on raw foods such as leaves, roots, nuts, and meats was hard on their teeth! In those days, dental hygiene was poor, and tooth loss was common.. By the time a person had reached his or her 20s, it was not unusual to have lost a tooth or two to decay. Without enough teeth, ancient people would not have been able to chew the foods they found and risked starvation.. Anthropologists believe ...
Just as there are a number of ways to lighten or brighten teeth, there are also several different ways for teeth to become discolored. The main causes of darkened teeth are genetics, antibiotics, and certain foods, plus teeth tend to darken as we age. Internal tooth discoloration is caused by changes in the enamel of the tooth and the dentin. The main causes of internal tooth discoloration are exposure to high levels of fluoride, tetracycline, use of antibiotics as a child, developmental disorders, tooth decay, restorations, root canal issues, and trauma.External tooth discoloration is caused by factors outside the body, mainly foods and tobacco. The main causes of external tooth yellowing are smoking, foods with tannins, coffee, tea, carrots, oranges, and other foods.. ...
At our dental office, tooth extractions, or the removal of a tooth from the mouth, (called exodontia), is performed for a wide variety of reasons. The main causes for tooth extractions are: Sever tooth decay which deems the tooth to be un-repairable, or acute/ chronic alveolar abscess. Some other of causes are: extra teeth that block other teeth from coming in, preparation for orthodontic treatments like braces, teeth in the fracture line, or fractured teeth. Extractions of impacted or problematic wisdom teeth are also routinely performed depending varying on an as needed treatment.. ...
A primary tooth pulpotomy is sometimes called a baby tooth root canal. It is performed on baby teeth with extensive decay that has affected the nerve of the tooth. The affected part of the nerve and the blood supply of the tooth (also called the pulp) are removed and the remaining part of the pulp is treated with a medication. Following a pulpotomy, the tooth usually needs a stainless steel crown. The purpose of a pulpotomy is to save a decayed baby tooth, so that the tooth can hold the space for the permanent tooth to come in. An alternative to the pulpotomy is an extraction (tooth removal), followed by a space-maintainer.. ...
Dr. Richard Dailey may determine that you need a tooth extraction for any number of reasons. Some teeth are extracted because they are severely decayed; others may have advanced periodontal disease, or have broken in a way that cannot be repaired. Other teeth may need removal because they are poorly positioned in the mouth (such as impacted teeth), or in preparation for orthodontic treatment.. The removal of a single tooth can lead to problems related to your chewing ability, problems with your jaw joint, and shifting teeth, which can have a major impact on your dental health. To discuss tooth extractions, please feel free to contact us at 336-513-0576 to schedule an appointment.. To avoid these complications, in most cases, Dr. Richard Dailey will discuss alternatives to extractions as well replacement of the extracted tooth.. The Tooth Extraction Process.

Tooth extractions are surgical procedures, which are commonplace in the world of dentistry and can be done in the offices of Making Orlando Smile - Cosmetic & Restorative Dentistry. Some tooth extractions may be of the simple nature where in the tooth has erupted from the gum. In cases like these, there is no invasive procedure needed. However, with teeth that are deep set, it may be necessary to cut into the gum and extract the tooth through there.. People who are most likely to be in need of tooth extractions have a large amount of damage on their teeth along with those who have impacted teeth. Impacted teeth are those which can erupt fully into the gum line and are mostly the wisdom teeth.. Before the procedure can be done, Dr. Maxine Moncrieffe will need to assess the situation in the patients mouth with the use of an x-ray along with a file on the patients dental history. In order to get the best method for extraction, the dentist will use the x-ray and determine the path to take. It may ...

Pituitary adenylate cyclase activating polypeptide (PACAP) is a pleiotropic neuropeptide with widespread distribution. It plays pivotal role in neuronal development. PACAP-immunoreactive fibers have been found in the tooth pulp, and recently, it has been shown that PACAP may also play a role in the regeneration of the periodontium after luxation injuries. However, there is no data about the effect of endogenous PACAP on tooth development. Ectodermal organogenesis including tooth development is regulated by different members of bone morphogenetic protein (BMP), fibroblast growth factor (FGF), hedgehog (HH), and Wnt families. There is also a growing evidence to support the hypothesis that PACAP interacts with sonic hedgehog (SHH) receptor (PTCH1) and its downstream target (Gli1) suggesting its role in tooth development. Therefore, our aim was to study molar tooth development in mice lacking endogenous PACAP. In this study morphometric, immunohistochemical and structural comparison of molar teeth ...
Insulin-dependent type-1 diabetes mellitus (DM) and oral diseases are closely interrelated. Poor metabolic control in diabetics is associated with a high risk of gingivitis, periodontitis and tooth loss. Salivary flow declines in diabetics and patients suffer from xerostomia. Reduced saliva predisposes to enamel hypomineralization and caries formation; however, the mechanisms that initiate and lead to progression of tooth decay and periodontitis in type-1 DM have not been explored. To address this issue, we analyzed tooth morphology in Akita-/- mice that harbor a point mutation in the Ins2 insulin gene which leads to insulin deficiency and hyperglycemia. Objective: To characterize the tooth phenotype in Akita-/- mice and determine whether hyperglycemia and hyposalivation contribute to dental defects. Methods: Mandibles from Akita-/- and wild type littermates were analyzed by microCT, scanning EM and histology; teeth were examined for amelogenin and ameloblastin expression. Mice were injected ...
Ask any kid and theyll tell you just how valuable baby teeth really are-out of the mouth, of course, and under their pillow awaiting a transaction with the Tooth Fairy. But theres more to them than their value on the Fairy Exchange Market-they play a critical role in future dental health.. Primary teeth provide the same kind of dental function as their future replacements. Children weaned from nursing can now eat solid food. They provide contact points for the tongue as a child learns to speak. And they play a role socially, as children with a toothsome smile begin to look more like what they will become when theyre fully mature.. But primary teeth also serve as guides for the permanent teeth that will follow. As a future tooth develops below the gum line, the primary tooth preserves the space in which it will erupt. Otherwise, the space can be taken over by other teeth. This crowds out the intended tooth, which may erupt out of position or remain impacted below the gum line.. In either ...

In healthy teeth, the tooth is optimally protected by one of natures hardest substances, tooth enamel. This covers the tooth from the crown to the gum line. The adjoining cervix does not have any enamel on its own, but in the healthy state it is surrounded by the gingiva like a collar and in this way also well protected.. But if the gums go back, the sensitive tooth necks are exposed. Stimuli such as B. Hot or cold can now pass through fine dentinal tubules directly into the tooth nerve and thereby cause drawing pain.. The most common cause of regression of the gums is periodontal disease, an inflammation of interdental spaces and other parts of the periodontium. Even brushing your teeth can hurt, so that oral hygiene is quickly neglected. As a result, the inflammation can spread further and expose the tooth necks even more. As a disease of the dental bed, periodontitis is regarded as a major trigger of tooth loss. However, early detection and sustainable treatment prevent this loss.. In ...
The potential from dental pulp stem cells include developing nerve and brain tissue, repairing muscle, developing bone, developing bone and tissue from the oral cavity, reconstructing affected cardiac tissue, developing cartilage, and treating type 1 diabetes to name a few. In the past, researchers harvested stem cells taken from bone marrow to create cells of various organs, however years of research implies that dental stem cells extracted from a tooth pulp might build organ tissues more quickly. Of major relevance is that UK scientists have ascertained that stem cells derived from tooth pulp effectively prevent a leading cause of blindness caused by traumatic injuries or degenerative diseases as reported in a July 2014 study on Neural Regeneration Research (Vol. 9, No. 6, 2014), University Of Birmingham, UK ...
What kind of cracks can affect the teeth?. There are many ways in which a tooth can be cracked. The specific type of crack will determine what type of treatment is viable. In many cases, if the crack is not too deep, root canal therapy can be performed and the natural tooth can remain in the mouth. In other situations, the tooth is too badly damaged and requires extraction.. Here is a brief overview of some of the most common types of cracks:. Crazes - These are generally tiny vertical cracks that do not place the teeth in danger. These scratches on the surface of the teeth are considered by most dentists to be a normal part of the tooth anatomy. A craze rarely requires treatment for health reasons, but a wide variety of cosmetic treatments can be performed to reduce the negative aesthetic impact.. Oblique supragingival cracks - These cracks only affect the crown of the tooth and do not extend below the gum line. Usually, the affected part of the tooth will eventually break off. Little pain will ...

Different Types Of Stains. By means of teeth whitening in Walnut Creek, you could be able to have your teeth stains and all the other food debris removed from your teeth. Whitening can also be greatly related to cleaning as well that is why this is something that you should definitely do for your teeth. There can be a lot of stains that your teeth could be able to encounter which can be further divided into intrinsic and extrinsic stains. Usually, extrinsic stains is a type of stains that can be found directly on the teeth surface and can be easily noticed. Most can be simply removed with routine brushing and cleaning. On the other hand,the intrinsic stains are the type that can be found within the teeth which mean that it can be more difficult to remove. If the intrinsic stains are usually caused by different food particles, the extrinsic stains are those that are caused by aging, trauma and exposure of the teeth to harmful chemicals. This type of stain is removed by the means of expert teeth ...
Orthodontic cases work by straightening and aligning your teeth over time. The wires put pressure on your teeth so that they can move in the right direction. In order for them to move, there has to be space in your jaw. Your orthodontist will access the space required to align your teeth and the space you have available in your jaw. If your teeth are overcrowded and theres not enough space, then some teeth will have to be extracted to make space for the movement of the teeth as they are realigned. An alternative to teeth extraction, in this case, is increasing the dental arches.. Crowding can be mild or serious. Mild crowding of the teeth can be resolved by other methods aside from extraction such as expanders (Dentofacial Orthopedics). Cases can also help fix crowding of teeth. This is common for children below 15 years of age.. Serious cases of overcrowding are more complex and most of the time extraction will be necessary. However, because people differ in bone structure and facial features, ...
The main goal of dentistry is to preserve your natural teeth and keep them healthy for as long as possible. There are times, however, when it is in your best interest (or your childs) to have a tooth extracted (removed). This could be the case for a variety of reasons. Perhaps you have a tooth that has been severely damaged by trauma or decay; or an impacted wisdom tooth that may cause trouble for you later on. Maybe your teenager will soon undergo orthodontic treatment and has insignificant space for his adult teeth, referred to as crowding. Or your younger child has a baby tooth thats stubbornly adhering, even though its past time for it to go.. Whatever the reason, tooth extraction is more often than not a very routine procedure. How straightforward this minor surgery is will depend on where the tooth to be extracted is located in the mouth, and what its roots are like. For example, a front tooth with a single straight root is easier to remove than a molar with multiple roots. This is ...
