In vitro comparison of the retention capacity of new aesthetic brackets. (1/1061)

Tensile bond strength and bond failure location were evaluated in vitro for two types of aesthetic brackets (non-silanated ceramic, polycarbonate) and one stainless steel bracket, using bovine teeth as the substrate and diacrylate resin as the adhesive. The results show that metallic bracket had the highest bond strength (13.21 N) followed by the new plastic bracket (12.01 N), which does not require the use of a primer. The non-silanated ceramic bracket produced the lowest bond strength (8.88 N). Bond failures occurred mainly between bracket and cement, although a small percentage occurred between the enamel-cement interface with the metal and plastic brackets and within the cement for the plastic bracket. With the ceramic bracket all the failures occurred at the bracket-cement interface. This suggests that the problems of enamel lesions produced by this type of bracket may have been eliminated. The results also show that the enamel/adhesive bond is stronger than the adhesive/bracket bond in this in vitro study.  (+info)

The crystal growth technique--a laboratory evaluation of bond strengths. (2/1061)

An ex vivo study was carried out to determine differences in the bond strengths achieved with brackets placed using a crystal growth technique compared with a conventional acid-etch technique. A solution of 37 per cent phosphoric acid was used for acid-etching and a commercially available polyacrylic acid gel, Crystal-lok for crystal growth. A heavily-filled composite resin was used for all samples to bond brackets to healthy premolar teeth extracted for orthodontic purposes. Polycrystalline ceramic and stainless steel brackets were used and tested to both tensile and shear failure using an Instron Universal Testing machine. The tensile and shear bond strengths were recorded in kgF. In view of difficulties experienced with previous authors using different units to describe their findings, the data were subsequently converted to a range of units in order to facilitate direct comparison. The crystal growth technique produced significantly lower bond strengths than the acid-etch technique for ceramic and stainless steel brackets, both in tensile and shear mode. The tensile bond strength for stainless steel brackets with crystal growth was 2.2 kg compared with 6.01 kg for acid-etch, whilst with ceramic brackets the tensile bond strengths were 3.9 kg for crystal growth and 5.55 kg for acid-etch. The mean shear bond strength for stainless steel brackets with crystal growth was 12.61 kg compared with 21.55 kg for acid-etch, whilst with ceramic brackets the shear bond strengths were 7.93 kg with crystal growth compared with 16.55 kg for acid-tech. These bond strengths were below those previously suggested as clinically acceptable.  (+info)

Pathological evaluation of the effects of intentional disocclusion and overloading occlusion in odontogenesis disorders in N-methylnitrosourea-treated hamsters. (3/1061)

This study compares the effects of disocclusion and overloading occlusion on dental lesions. Ten-day-old Syrian hamsters were divided into 4 groups: group I, untreated animals; group II, animals whose hemilateral incisors were disoccluded; group III, N-methylnitrosourea (MNU)-treated animals; and group IV, MNU-treated animals whose hemilateral incisors were disoccluded. The ipsilateral maxillary and mandibular incisors were repetitively cut with diamond discs. The hamster is easier to anesthetize. Animals received a 0.2% solution of MNU (10 mg/kg body weight) intragastrically twice a week for 16 wk. All the cut mandibular incisors and the MNU-treated uncut mandibular incisors showed lack of iron deposition on the enamel surface. The eruption rate was significantly higher in the cut disoccluded incisors of groups II and IV (p < 0.05) and significantly lower in the uncut overloaded incisors of groups II and IV (p < 0.05). In the cut mandibular incisors of group IV, the degree of the disturbance of odontogenesis and the atypical proliferation of odontogenic epithelium were more prominent (p < 0.02), and the dental lesions occurred earlier. Histologically, the disturbed Hertwig's epithelial sheath and the Hertwig's epithelial sheath-like transformed U-shaped part and enamel organ seemed to lead to disturbances of amelogenesis and detinogenesis as well as to atypical proliferation of odontogenic epithelium nests. Thus, this method of disocclusion of the incisors of rodents may represent a useful model for the investigation of the effects of various agents on tooth formation over a short experimental period.  (+info)

Super pulse CO2 laser for bracket bonding and debonding. (4/1061)

A super pulse and a normal pulse CO2 laser were used to carry out enamel etching and bracket debonding in vitro and in vivo. The shear bond strength of the orthodontic brackets attached to laser-etched and conventional chemically-etched extracted premolars was measured. The pulp cavity temperature was also measured using the same laser irradiation conditions as the shear test. Both super pulse and normal pulse CO2 laser etching resulted in a lower shear bond strength (super pulse: 6.9 +/- 3.4 kg, normal pulse: 9.7 +/- 5.2 kg) than that of chemical etching (15.3 +/- 2.8 kg). Furthermore, the super pulse CO2 laser was able to create debonding at 2 watts within a period of less than 4 seconds (2.9 +/- 0.9 seconds). The super pulse, when irradiating the ceramic brackets from above, during debonding showed a 1.4 degrees C temperature increase in the dental pulp at 2 watts and an increase of 2.1 degrees C at 3 watts. While etching, directly irradiating the enamel surface at 3 watts, the dental pulp showed a temperature increase of 3.5 degrees C. These temperature increases were within the physiologically acceptable limits of the pulp. These results indicate that, in orthodontic treatments, super pulse CO2 laser debonding is more useful than laser etching.  (+info)

An immunocytochemical study of amelogenin proteins in the developing tooth enamel of the gar-pike, Lepisosteus oculatus (Holostei, Actinopterygii). (5/1061)

Previous studies have demonstrated the morphological similarity of the enamel-like layer found in the teeth of the coelacanth, lungfish and gar-pike to the enamel of tetrapods. In order to clarify the phylogenetic continuity between both structures, tooth germs of the gar-pike were immunocytochemically studied using an anti-bovine amelogenin polyclonal antibody. Intense immunoreaction was shown over the enamel-like matrix layer. Certain cell organelles associated with the secretory pathway of the ameloblasts were recognized as immunoreactive. These results indicate that the enamel-like layer of the gar-pike is a tissue homologous with the mammalian enamel because both possess a common, amelogenin-like substance.  (+info)

Aspects of cell proliferation kinetics of the inner dental epithelium during mouse molar and incisor morphogenesis: a reappraisal of the role of the enamel knot area. (6/1061)

First lower E-14 and E-16 mouse molars and E-13 lower incisors were cultured in vitro and either sequentially or continuously labelled with BrdU (5-bromo-2'-deoxyuridine). The behaviour of the non-cycling inner dental epithelial cells emerging from the enamel knot area of the molars was analysed by 3D (three dimensional) reconstructions of serial sections. These cells, as well as slow cycling cells underwent a coordinated temporo-spatial patterning leading to their patchy segregation at the tips of the forming cusps. In incisors (in vitro and in vivo), non-cycling cells were also present in the inner dental epithelium of the enamel knot area. However, these cells were not redistributed during incisor morphogenesis. These non-dividing inner dental epithelium cells of the enamel knot area which are either redistributed or not according to the tooth type specific morphogenesis might represent the organizers of morphogenetic units (OMU), the cusps.  (+info)

A laboratory investigation to compare enamel preparation by sandblasting or acid etching prior to bracket bonding. (7/1061)

A laboratory investigation to compare the mean shear debonding force and mode of bond failure of metallic brackets bonded to sandblasted and acid-etched enamel is described. The buccal surfaces of 30 extracted human premolars were sandblasted for 5 seconds with 50 mu alumina and the buccal surfaces of a further 30 human premolars were etched with 37 per cent phosphoric acid for 15 seconds. Following storage for 24 hours at 37 degrees C in distilled water, shear debonding force was measured using an Instron Universal Testing Machine with a cross-head speed of 10 mm/minute. Mean shear debonding force was significantly lower for brackets bonded to sandblasted enamel compared to acid etched enamel (P < 0.001). Weibull analysis showed that at a given stress the probability of failure was significantly greater for brackets bonded to sandblasted enamel. Brackets bonded to etched enamel showed a mixed mode of bond failure whereas following sandblasting, failure was adhesive at the enamel/composite interface (P < 0.01).  (+info)

Biodosimetry results obtained by various cytogenetic methods and electron spin resonance spectrometry among inhabitants of a radionuclide contaminated area around the siberian chemical plant (Tomsk-7). (8/1061)

On April 6, 1993, near the town of Tomsk (Russia) there was an accident at the Siberian Chemical Plant (SCP) which resulted in extensive contamination of an area of 250 km(2) to the north of SCP with long-lived radionuclides such as (239)Pu, (137)Cs and (90)Sr. Cytogenetic methods and electron spin resonance (ESR) spectrometry of tooth enamel were used to estimate the radiation doses received by the population. The ESR signal intensity and the chromosomal aberration frequency in lymphocytes of the tooth donors showed a good correlation. The data showed that 15% of the inhabitants of the Samus settlement received a radiation dose >90 cGy. The exceptions were results of an examination of fishermen, where ESR gave high values (80-210 cGy) but both the chromosome assay and the cytokinesis block micronucleus method gave lower ones (8-52 cGy). A large increase in chromosome damage was observed in people born between 1961 and 1969. It was found that during these years several serious accidents at the Siberian Chemical Plant had occurred causing radiation pollution of the area. The number of cells with chromosome aberrations was significantly less among the people arriving in Samus after 1980. We found good correlations between the level of carotene consumption and a decrease in frequency of both micronuclei in binucleated lymphocytes (r = 0.68, P < 0.01) and chromatid aberrations (r = 0.61, P < 0.01) among the inhabitants. We also examined the inhabitants of Samus for opisthorchis infection, which was present in 30% of the population. The Samus inhabitants affected by Opisthorchis felineus showed significantly increased levels of micronuclei in binucleated lymphocytes and chromatid aberrations as compared with the controls.  (+info)

Dental enamel is one of the hardest materials of the human body . Yet, as is well known, enamel can be destroyed by acids present in dietary components, especially in soft drinks. This destructive process, occurring without the involvement of bacteria, is known as dental erosion . The process of dental erosion is influenced by a number of extrinsic and intrinsic factors including the formulation of the soft drinks, biological factors and the socio-economic status of the consumer . An important approach to reduce erosion is to modify the erosive agents and, thus, to reduce the erosive effects against human dental enamel. The process of enamel dissolution caused by acids was investigated in several studies. Surface softening and enamel loss are most often caused by the consumption of acidic soft drinks containing citric and/or phosphoric acids . Enamel surfaces can be characterized by profilometry to measure the loss of dental enamel dependent on e.g. pH, acid concentration and time. Atomic force ...
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
The present work concerns the development of liposomal formulations that can adsorb to the human dental enamel. The overall aim of this pharmaceutical approach is to physically protect the teeth against detrimental processes, such as tooth wear, acidic challenges and dental caries. Adsorption experiments of different liposomal formulations to hydroxyapatite (HA), a model substance for the dental hard tissue, and the human dental enamel were performed. To find which liposomal formulations are promising for the adsorption to teeth, formulation factors important for the interaction were initially mapped by the use of experimental design and multivariate analysis (Paper I). The type of surface charge became the most significant factor for the adsorption process. Positively charged liposomes adsorbed better than the negatively charged liposomes to HA in phosphate buffer, pH 6.8-7. However, the adsorption of positively charged liposomes to HA in a salivary environment was interfered as they were found ...
Purpose: To establish methods to quantitate the physical surface change, not the chemical color bleaching change, of enamel occurring with hydrogen peroxide treatment in solution and commercially available plastic strips. Methods: Bovine enamel was polished to a sound, uniform, optical flat, white subsurface that was used as the initial substrate for all substrate modification, treatment and instrumental measurement using digital photography-image analysis, SEM and profilometry. Sound enamel was treated with 10, 20 and 30% solutions of hydrogen peroxide. Plastic strips were used to treat both sound and acid modified enamel surfaces. Etched enamel, similar to a 10-second exposure to lemon juice, was treated with 0.5, 1, 3, 5, 10, and 15% hydrogen peroxide for 24-hour exposure at 37 degrees C to obtain a dose response curve to this modified enamel. Results: The digital photography-image analysis system and scanning electron microscopy (SEM) were effective in detecting enamel surface porosity and ...
Objective: This study examined the shear bond strength of bonding agents to normal or fluoridated enamel following use of weak or strong acids to prepare enamel surfaces and after contamination with a measured amount of saliva at various stages of the bonding procedure. Method and materials: One hundred extracted human third molar teeth were randomly separated into 2 basic groups (normal or fluoridated teeth), then divided into 5 subgroups. Group A specimens were not contaminated. After etching, enamel surfaces were dry and clean. Group B was left with wet surfaces after etching. Group C specimens were contaminated with artificial saliva and then dried. Group D specimens were contaminated with artificial saliva, rinsed, and then dried. In group E, all enamel surfaces were left contaminated with saliva after the etching procedures (with maleic acid or phosphoric acids). Adhesive resins were applied to all enamel surfaces according to the manufacturer s instructions. The specimens were then ...
Numerous studies have demonstrated the effects of laser-induced heat on demineralization of enamel; however, no studies have investigated the link between heat/laser-induced changes in physicochemical properties and bacterial adhesion. In this study, we investigated the effects of thermal treatment on surface properties of enamel such as hydrophobicity and zeta potential. Bacterial adhesion to treated surfaces was characterized by confocal laser scanning microscopy, and adhesion force was quantified by atomic force microscopy. The hydrophobicity of enamel increased after heating (p < 0.05), and the zeta potential of heated enamel became more negative than that of the control (p < 0.01). Streptococcus oralis and S. mitis were more hydrophilic than S. sanguis, with more negative zeta potential (all p < 0.01). S. mitis and S. oralis occupied significantly less area on enamel after being heated (p < 0.05). Heating reduced the adhesion force of both S. mitis and S. oralis to enamel with ...
Fluoride is anticariogenic, meaning it prevents tooth decay. Significant clinical studies support the use of fluoride in dental care, recommending that patients brush teeth twice daily with a fluoride toothpaste. Fluoride strengthens tooth enamel by both inhibiting the demineralization of enamel, as well as enhancing the remineralization of decalcified enamel in the early stages of tooth decay. When given systemically prior to the eruption of permanent teeth, the fluoride ion is incorporated into the apatite crystal of the bone and teeth, stabilizing and strengthening the tooth.16 Topical fluoride is also incorporated into the enamel structure, thus fluoride is still effective for caries prevention in children and adults with permanent teeth.17 Fluoride incorporated into the enamel increases the enamels resistance to acid, inhibiting the demineralization of enamel. Enamel with a greater concentration of fluoride has an improved structure and is more resistant to acid.18 In decalcified enamel, ...
Infraction is a disruption of enamel prisms without loss of tooth substance extending from the enamel surface to the dentino-enamel junction (right lateral incisor). Enamel fracture is the loss of tooth substance confined to enamel (right central incisor). Enamel-dentin fracture (uncomplicated crown fracture) is the loss of tooth substance confined to enamel and dentin, but not involving the pulp (left central incisor).. Fractures may appear as craze lines within the enamel (infractions) or as loss of tooth substance involving only enamel or enamel and dentin. Infraction lines are usually best seen when the light beam is directed parallel to the long axis of the tooth. Besides describing only the most obvious injury (i.e. crown fracture), it is very important to diagnose concomitant luxation injuries, as these have a very significant influence on pulpal outcome.. RADIOGRAPHIC APPEARANCE. ...

The purpose of this study was to evaluate and compare enamel micro-crack characteristics of adult patients before and after removal of metal brackets. After the examination with scanning electron microscopy (SEM), 45 extracted human teeth were divided into three groups of equal size. The length and width of the longest enamel micro-crack were measured for all the teeth before and after removal of metal brackets. The changes in the location of the micro-cracks were also evaluated. New enamel micro-cracks were found in 6 of 15 (40 per cent) examined teeth. Greatest changes in the width of enamel micro-cracks after debonding procedure appear in the cervical third of the tooth. On the basis of this result, the dentist must pay extra care and attention to this specific area of enamel during removal of metal brackets in adult patients.. ...

Our previous clinical study indicates tooth-level radiation dose significantly impacts post-radiation dentition breakdown. Three tiers of dose-response were identified: minimal damage (below 30Gy), 2-3x increase (between 30 and 60Gy-salivary gland threshold), and 10x increase in tooth damage at ≥60Gy suggesting a direct effect on tooth structure. Objectives: To understand the mechanism of radiotherapy-induced dental lesions characterized by shear fracture of enamel near the dentin-enamel junction (DEJ) that suggests decreased interface stability. Methods: An in vitro model was used to examine the effects of radiotherapy, elapsed time following radiation, and occlusal function on the nano-mechanical properties of enamel and dentin near the DEJ. Initial studies were completed on 16 extracted, unerupted third molars with one-half of the teeth exposed to 70 Gy or no radiation followed by 1 or 3 mo PBS storage at 37 C. Half the teeth from each radiation dose/elapsed time group were exposed to ...
In Turner syndrome (TS) one X-chromosome is missing or defective. The amelogenin gene, located on the X-chromosome, plays a key role during the formation of dental enamel. The aim of this study was to find support for the hypothesis that impaired expression of the X-chromosome influences mineral incorporation during amelogenesis and, indirectly, during dentinogenesis. Primary tooth enamel and dentin from girls with TS were analysed and compared with the enamel and dentin of primary teeth from healthy girls. Qualitative and quantitative changes in the composition of TS enamel were found, in addition to morphological differences. Higher frequencies of subsurface lesions and rod-free zones were seen in TS enamel using polarized light microscopy. Similarly, scanning electron microscopy showed that the enamel rods from TS teeth were of atypical sizes and directions. Using X-ray microanalysis, high levels of calcium and phosphorus, and low levels of carbon, were found in both TS enamel and dentin. ...

Materials and Methods: Buccal enamel of 80 bovine teeth was submitted to finishing and polishing with metallographic paper to a refinement of #600, in order to obtain a 5-mm2 flat area. Blocks (2 x 4 x 4 mm) of laboratory composite resin were cemented to enamel according to different protocols: (1) untreated enamel + RelyX Unicem cement (RX group); (2) untreated enamel + Bifix SE cement (BF group); (3) enamel acid etching and application of resin adhesive Single Bond + RelyX Unicem (RXA group); (4) enamel acid etching and application of resin adhesive Solobond M + Bifix SE (BFA group). After 7 days of storage in distillated water at 37°C, the blocks were sectioned for obtaining microbar specimens with an adhesive area of 1 mm2 (n = 120). Specimens were submitted to the microtensile bond strength test at a crosshead speed of 0.5 mm/min. The results (in MPa) were analyzed statistically by ANOVA and Tukeys test ...
The objectives of this research were to prepare and characterize inclusion complexes of Nitrazepam with Hydroxypropyl-β-cyclodextrin (HPβCD) and Sulfobutyl ether β-cyclodextrin (SBEβCD) to study the effect of complexation on the dissolution rate of Nitrazepam, a water-insoluble drug. The phase solubility profile of Nitrazepam with Hydroxypropyl- β-cyclodextrin and Sulfobutyl ether β-cyclodextrin was an AP-type, indicating the formation of 2:1 stoichiometric inclusion complexes. Gibbs free energy values were all negative, indicating the spontaneous nature Nitrazepam solubilization and their value decreased with increase in the cyclodextrin concentration, demonstrating that the reaction conditions became more favorable as the concentration of cyclodextrins increased. Complexes of Nitrazepam were prepared with cyclodextrin using various methods such as physical mixing, kneading, spray-drying and lyophilization. The complexes were characterized by Differential scanning calorimetry, ...
Enamel Loss. Before getting to the part about prevention of enamel decay and tooth whitening, it is important to know that what is meant by the enamel loss. To begin with, the enamel of the tooth is the protective layer present on the outer side of the teeth and the main purpose is to safeguard the softer and more sensitive layers or parts of the tooth. But the problem is that if people have bad eating habits in terms of overusing the sugar and citric fruits or starch, the layer of enamel is likely to get affected by it. This is why it is recommended by the Eugene dentist that brushing should not be taken lightly and if your routine allows you to, you can floss your teeth twice a day to prevent the enamel damage. Moreover, the negative implication of chipped tooth can also enhance the chances of damage to the enamel. In addition, the role of teeth clenching and grinding will aggravate the process of harm to the teeth and ultimately your teeth may get pale.. Symptoms of Enamel Loss. If you notice ...
There are numerous well documented medical studies that show the deleterious affect of soft drinks on dental enamel. Non-cola beverages fared worst and dental problems were greatly accelerated by both regular and dietetic drinks, though the absence of sugar lessened decay. Recently sports drinks have been added to the studies with the surprising finding that they result in enamel deterioration equal to or worse than the non-cola beverages! Several different mechanisms are at work but the main problem is that almost all of these products contain phosphoric or citric acid. Other organic acids such as malic and tartaric are often present as well. These acids are very erosive to dental enamel due to their ability to chelate calcium. They are efficient buffers and keep oral pH well below the optimal salivary pH of 6.5 to 7.5. The threshold level for the development of dental caries is below Ph 5.5. Enamel demineralization occurs with prolonged exposure to lower pH or frequent cycling between optimal ...

Many first impressions are formed by the whiteness and straightness of your teeth. This external view of your teeth is important, but whats inside your teeth is even more important to your overall health and the attractiveness of your smile. From the outside, each tooth looks like a solid white object, but actually teeth are composed of several layers of complex living tissues, which include enamel, dentin, pulp and cementum.. Enamel. Enamel is the white, thin [only 1 to 2 mm thick] outermost layer of a tooth. It is the part of your tooth that you see above the gum line. Enamel is the hardest substance in your body and the second hardest substance in nature. Only diamonds are harder. Actually, I use small diamonds burs to be able to drill through enamel. Teeth are a major find in the fossil record, due to enamels hardness being the last feature to dissolve.. Enamel provides strength for biting and chewing and it protects the inner layers from plaque and bacteria that lead to decay. Though ...

An unresolved problem in tooth enamel studies has been to analyze simultaneously and with sufficient spatial resolution both mineral and organic phases in their three dimensional (3D) organization in a given specimen. This study aims to address this need using high-resolution imaging to analyze the 3D structural organization of the enamel matrix, especially amelogenin, in relation to forming enamel crystals. Chemically fixed hemi-mandibles from wild type mice were embedded in LR White acrylic resin, polished and briefly etched to expose the organic matrix in developing tooth enamel. Full-length amelogenin was labeled with specific antibodies and 10 nm immuno-gold. This allowed us to use and compare two different high-resolution imaging techniques for the analysis of uncoated samples. Helium ion microscopy (HIM) was applied to study the spatial organization of organic and mineral structures, while field emission scanning electron microscopy (FE-SEM) in various modes, including backscattered electron

Objective. To determine the translucency of human and bovine enamel and dentin using reflection spectrophotometers. Material and Methods. The color of intact human and bovine enamel and dentin specimens was measured over a white and a black plasticine backing using two spectrophotometers with different aperture sizes; translucency parameter (TP) and contrast ratio (CR) were calculated. Plasticine was used as backing because the specimens were not uniform. The TP values of five composite resins measured over the backings of plasticine and reflectance standards were also determined. Results. There were no significant differences between the TP values of the composite resins measured over the backings of plasticine and reflectance standards (p,0.05). Mean TP values of 1 mm thick bovine enamel, bovine dentin, human enamel and human dentin were 14.7, 15.2, 18.7, and 16.4, respectively, based on the 3 mm round aperture. There were significant correlations between the TP values measured by the two ...
The specimens were found in Argentinas Río Negro province as part of ongoing collaborative fieldwork and research between Michael Caldwell, professor in the Department of Biological Sciences and the Department of Earth and Atmospheric Sciences, and Argentinian paleontologist and fieldwork leader Sebastián Apesteguía. In order to look more closely at the teeth of Priosphenodon, the researchers cut open pieces of jaw and examined tissue-level detail preserved inside the teeth. They also used non-invasive CT scans to examine more complete jaw specimens.. Priosphenodon enamel is not only thicker than that of most other reptiles, the enamel crystals are woven into long threads that run through the whole width of the enamel. These threads are called enamel prisms, and they are almost exclusively found in mammals, said LeBlanc, who is working under Caldwells supervision. Our results suggest that strong selective pressures can force reptiles to come up with some very innovative solutions to ...

Author(s): Katsura, Kaitlin A | Advisor(s): Den Besten, Pamela | Abstract: Amelogenesis Imperfecta (AI) is a clinical diagnosis that encompasses a group of genetic mutations, each affecting processes involved in tooth enamel formation and thus, result in various enamel defects. The hypomaturation enamel phenotype has been described for mutations involved in the later stage of enamel formation, including Klk4, Mmp20, C4orf26, and Wdr72. Using a candidate gene approach we discovered a novel Wdr72 human mutation, resulting in a hypomaturation AI phenotype, to be a 5-base pair deletion (c.806_810delGGCAG; p.G255VfsX294). To gain insight into the function of WDR72, we used computer modeling of the full-length human WDR72 protein structure and found that the predicted N-terminal sequence forms two beta-propeller folds with an alpha-solenoid tail at the C-terminus. This domain iteration is characteristic of vesicle coat proteins, such as beta′-COP, suggesting a role for WDR72 in the formation of membrane
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 ...
Recent work has disclosed the critical role played by enamel peptides in sex classification of old skeletal remains. In particular, protein AMELY (amelogenin isoform Y) is present in the enamel dental tissue of male individuals only, while AMELX (isoform X) can be found in both sexes. AMELY can be easily detected by LC-MS/MS in the ion extracted chromatograms of the SM(ox)IRPPY peptide (monoisotopic [M + 2 H]+2 mass = 440.2233 m/z). In this paper, we exploited the dimorphic features of the amelogenin protein to determine the sex of the so-called Lovers of Modena, two Late Antique individuals whose skeletons were intentionally buried hand-in-hand. Upon discovery, mass media had immediately assumed they were a male-female couple, even if bad preservation of the bones did not allow an effective sex classification. We were able to extract proteins from the dental enamel of both individuals (~1600 years old) and to confidently classify them as males. Results were compared to 14 modern and archaeological
Tooth enamel is one of the four major tissues that make up the tooth in humans and many other animals, including some species of fish. It makes up the normally visible part of the tooth, covering the crown. The other major tissues are dentin, cementum, and dental pulp. It is a very hard, white to off-white, highly mineralised substance that acts as a barrier to protect the tooth but can become susceptible to degradation, especially by acids from food and drink. Enamel is the hardest substance in the human body and contains the highest percentage of minerals, 96%, with water and organic material composing the rest. The primary mineral is hydroxyapatite, which is a crystalline calcium phosphate. Enamel is formed on the tooth while the tooth is developing within the gum, before it erupts into the mouth. Once fully formed, it does not contain blood vessels or nerves. Remineralisation of teeth can repair damage to the tooth to a certain degree but damage beyond that cannot be repaired by the body. ...
Objectives: In this study, morphological and chemical changes in teeth enamel exposed to alkaline agents, with or without surfactants, have been investigated. In addition, chemical effects of the organic surface layer, i.e. plaque and pellicle, were also investigated. Methods: The present study was conducted using several techniques: Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD) and scanning electron microscopy (SEM). Results: From XPS-measurements, it was found that exposure to alkaline solutions resulted in a massive removal of carbon from the tooth surface, and that the addition of surfactants increased the rate under present conditions. Based on the results from the FTIR-analysis, no substitution reactions between phosphate, carbonate and hydroxide ions in the enamel apatite could be detected. From a minor SEM-analysis, degradation and loss of substance of the enamel surface was found for the exposed samples. From XRD-analysis, no

Celiac Disease is an autoimmune disease, not a food allergy, which affects infants, children, and adults and results in a permanent intolerance to gluten - a protein found in wheat, rye, and barley.. The enamel defects range from slight defects in the color of enamel, with white, yellow, or brown opacities (spots), rough enamel, horizontal grooves, large vertical pits all the way to severe structural defects, with possible total loss of enamel (enamel hypoplasia).. Other causes of enamel defects are vitamin D deficiency, premature birth, dental fluorosis, trauma, localized infection, and the use of antibiotics.. Enamel defects are an important early indication that the child may suffer from Celiac Disease and is a non-invasive way for dentists to diagnose the condition in those with suspected disease, and should be a part of every oral examination - yet another good reason to have a dental exam by Dr. Geisler, a Plymouth, MN dentist.

This invention relates to non-aqueous compositions and methods utilizing same which are useful to remineralize subsurface dental enamel. More specifically, this invention relates to stable, single-part compositions containing calcium and phosphate salts which may be in a hydrophilic, non-aqueous vehicle and which when applied to lesions in dental enamel result in remineralization of subsurface dental enamel and/or mineralization of tubules in dentin thereby counteracting caries and/or hypersensitivity.
We brought our DD (who is now almost 19 months) for a checkup at a pediatric dentist and they found initial decay of her 4 top front teeth, probably due to enamel defect from birth. She seems to have this defect only in the top 4 front teeth. We ended up seeing two pediatric dentists and again her pediatrician about it, and we are quite confused now. Her pediatrician suggested to let it be; one dentist gave us a tooth mousse that contains calcium, to strengthen the enamel, with monthly
Dental veneers-thin, life-like layers of porcelain bonded to teeth-can turn a so-so smile into a beautiful one. But most veneers have a distinct drawback: To make them look as natural as possible, the teeth theyre bonded with must have some of their surface enamel removed.. Even though theyre 1 millimeter or less in thickness, veneers on an unprepared tooth can look bulky. Removing some of the surface enamel remedies this, but doing so permanently alters the tooth. The tooth will need a veneer or some other protective restoration from then on.. Now, though, theres an alternative veneer available for many dental patients. Known as No-Prep or Minimal-Prep, these new veneers are often as thin as a contact lens.. These new types of veneers can often be placed directly on the teeth just above the gum line without any enamel removal and look natural. At the most, the enamel beneath them may need reshaping with an abrasive tool. And, unlike traditional veneers with tooth alteration, these low-prep ...
What is acid erosion and where does it come from? • Dental erosion is loss of dental enamel caused by direct contact of the teeth with acids from everyday food and drinks. • Acids can soften and gradually dissolve the minerals in the enamel making teeth thinner, weaker and more sensitive. Introducing Colgate Sensitive ProRelief Enamel Repair Toothpaste. An exclusive ProArgin formula with technology to provide sensitivity relief. How does CSPR Enamel Repair toothpaste work? • Its ProArgin formula remineralises tooth enamel and makes teeth more resistant against repeated acid attacks. • It also blocks the exposed channels from damaged enamel that lead to sensitive tooth nerves. With regular use, it builds a reparative layer that acts like a seal, helping to repair sensitive teeth for lasting protection with twice daily brushing. Always read label and use as directed. If sensitivity persists see your dentist. Colgate-Palmolive, Lower Hutt, NZ. TAPS #PP6371

I must report this one…..My 25 year old granddaughter called. Shes been on the Calcarea fluorica and Calcarea phosphorica faithfully for 3 months. She has been plagued by tooth decay. To make it worse, she was a swimmer all through school- bad for tooth enamel. Today the dentist said her teeth look great and 3 cavity beginnings have not changed. This is good news since her teeth were showing decay and worsening at every previous 6 month dental visit. She also has seemed more grounded and stronger than before, although Ive always thought she is a strong kid. She just got engaged and has also been voted teacher of the year in her school district in Swansboro, NC.. This information (homeopathy) is a lifetime GIFT! Im so grateful ...

Following the entry of Zea mays to northeast North America, there are indications of human population growth, suggesting crop intensification. Isotopic values from bone collagen have been inconsistent with this hypothesis, showing temporal and regional fluctuations that have led to hypotheses of sporadic overreliance on this super-crop. Following Katzenbergs suggestion that intake of this carbohydrate should be measured through apatite rather than protein tissue, and with the permission of the Huron-Wendat Nation of Wendake, Quebec, we measured tooth enamel δ13C from 167 permanent tooth crowns (most M1), retained after reburial of the skeletons. Enamel values encapsulate diet from early childhood (3 to 4 years of age). The teeth represent 16 ancestral Huron-Wendat sites in southern Ontario. Isotopic values show a gradual increase in reliance on maize from the 14th to 17th centuries, perhaps reflecting development of crop strains that were more reliable at higher latitudes. This pattern of δ13C

Unlike skins or bones, the tooth enamel, which forms the hard surface of a tooth, does not regenerate itself once damaged. Therefore, the conventional dental treatment includes drilling of the decayed part of a tooth and filling the hole with resin or metal alloy dental materials.

Most people know that sweets are bad for their teeth, but far fewer realize theres a danger with sour treats, too. Regular and diet soft drinks, candies - especially sour ones - and foods such as lemons are acidic. Repeated and frequent exposure to acid wears away tooth enamel, leaving teeth sensitive, less attractive and vulnerable to decay.

Dental caries is the scientific term for tooth decay or cavities. Tooth decay is the destruction of your tooth enamel -- the hard, outer layer of your teeth. This issue can affect children, teens and adults. It is caused by specific types of bacteria. They produce acid that destroys the tooths enamel and the layer under it, the dentin. Many different types of bacteria normally live in the human mouth. They build up on the teeth in a sticky film called plaque. When you eat or drink foods or beverages containing sugars, the bacteria in plaque produce acids that attack tooth enamel. The stickiness of the plaque keeps these acids in contact with your teeth, and over time the enamel can break down. They are too small to see at first. But they get larger over time ...
Tooth sensitivity is often caused by the exposure of dentin on root areas due to receded gums or periodontal disease. Normally, the underlying dentin of the tooth (the layer that immediately surrounds the nerve) is covered by enamel in your tooths crown, and the gums that surround the tooth. This enamel covering may wear down over time, becoming thinner and providing less protection. Your gums can also recede over time, exposing the underlying root surface dentin. The dentin contains a large numbers of pores or tubes that run from the outside of the tooth to the nerve in the center. When the dentin is exposed, these tubes can be stimulated by changes in temperature or certain foods. Continue reading →. ...
Dentin is a calcified tissue of the body. Dentin, enamel, cementum and pulp, are the four major components that make up the teeth. It is often covered by enamel on the crown and cementum of the root and surrounds the tooths pulp. Dentin is comprised of 45% hydroxylapatite, 33% organic material and 22% water. Dentin is yellow in its appearance and greatly affects the tooths color because of the enamels translucency. Dentin is less mineralized and less brittle in comparison to enamel. It is also necessary for the support of the enamel. Dentin has a score of 3 on the Mohs scale of mineral hardness. Dentin forms throughout life and is very sensitive.. Dentinal sclerosis or transparent dentin-sclerosis of primary dentin is the regressive alteration in teeth caused by the calcification of the dentinal tubules. It can occur as a result of cavities, an abrasion or as part of the normal aging process. ...
