The root surface in human teeth: a microradiographic study. (1/1113)In an attempt to clarify the nature of the human cemento-dentinal junction, ground sections of incompletely formed and fully formed extracted teeth were prepared and their histology compared with their microradiographic appearances. The results showed that incompletely formed teeth possess distinctive surface layers outside the granular layer of Tomes. The evidence indicates that these layers are of dentinal origin; their presence during development supports previous explanations by the author of the hyaline layer of Hopewell-Smith and of so-called intermediate cementum. The results also indicate that the granular layer of Tomes does not represent the outer limit of root dentine. The relationship of these surface layers to the definitive cementum which is present in fully formed teeth was studied in both young and older patients. From the results it was concluded that cementum formation begins in the more apical region of the teeth at a time when root formation is well advanced, and that it spreads towards the crown rather than in the generally accepted reverse direction.

Predicting protein decomposition: the case of aspartic-acid racemization kinetics. (2/1113)The increase in proportion of the non-biological (D-) isomer of aspartic acid (Asp) relative to the L-isomer has been widely used in archaeology and geochemistry as a tool for dating. the method has proved controversial, particularly when used for bones. The non-linear kinetics of Asp racemization have prompted a number of suggestions as to the underlying mechanism(s) and have led to the use of mathematical transformations which linearize the increase in D-Asp with respect to time. Using one example, a suggestion that the initial rapid phase of Asp racemization is due to a contribution from asparagine (Asn), we demonstrate how a simple model of the degradation and racemization of Asn can be used to predict the observed kinetics. A more complex model of peptide bound Asx (Asn + Asp) racemization, which occurs via the formation of a cyclic succinimide (Asu), can be used to correctly predict Asx racemization kinetics in proteins at high temperatures (95-140 degrees C). The model fails to predict racemization kinetics in dentine collagen at 37 degrees C. The reason for this is that Asu formation is highly conformation dependent and is predicted to occur extremely slowly in triple helical collagen. As conformation strongly influences the rate of Asu formation and hence Asx racemization, the use of extrapolation from high temperatures to estimate racemization kinetics of Asx in proteins below their denaturation temperature is called into question. In the case of archaeological bone, we argue that the D:L ratio of Asx reflects the proportion of non-helical to helical collagen, overlain by the effects of leaching of more soluble (and conformationally unconstrained) peptides. Thus, racemization kinetics in bone are potentially unpredictable, and the proposed use of Asx racemization to estimate the extent of DNA depurination in archaeological bones is challenged. (+info)
Steric effects of N-acyl group in O-methacryloyl-N-acyl tyrosines on the adhesiveness of unetched human dentin. (3/1113)We have prepared various O-methacryloyl-N-acyl tyrosines (MAATY) to reveal the relationship between molecular structure near carboxylic acid and adhesive strength of MAATY-HEMA type adhesive resin to unetched dentin. In this study, we attempted to change the steric hindrance effect without changing the HLB value, i.e., introducing an iso-acyl group instead of n-acyl group into MAATY. O-methacryloyl-N-ethylbutyryl tyrosine (MIHTY) showed significantly lower adhesive strength when compared with O-methacryloyl-N-hexanoyl tyrosine even though both MAATY have the same HLB value. The possible explanation of the significantly different adhesive strength was that the 2-ethylbutyryl group in MIHTY was bulky, resulting in inhibition of the hydrogen bonding of the carboxylic group. The HLB value is independent of the steric effect of molecular structure, and thus the steric factor should be taken into consideration for the explanation of different adhesive strengths within the adhesive monomers having the same HLB value but different molecular structures.

Dentinal tubule occlusion with lanthanum fluoride and powdered apatite glass ceramics in vitro. (4/1113)To simulate hypersensitive dentin, the smear layer and dentinal plugs of bovine root dentin specimens were removed by immersion in 10% phosphoric acid, polishing with hydroxyapatite particles, and ultrasonic cleansing. The fluoride-tannic acid-lanthanum-apatite (FTLA) group was treated with acidulated phosphate fluoride (APF) containing tannic acid followed by rubbing with a paste of lanthanum chloride (LaCl3) and powdered apatite glass ceramics. The treated specimens were immersed in a remineralizing solution that mimics saliva for 6 weeks. The SEM observations revealed that the treated surfaces of the FTLA group were completely covered with fine spherical compounds and the dentinal tubules were occluded with plugs to a depth of about 3 microns. Fluoride and lanthanum were detected to a depth of over 20 microns by EPMA observation. After the remineralization, the surface of FTLA-treated specimen did not have any opened tubules and showed a remarkable increase in the number of fine spherical deposits in the dentinal tubules. These results suggest that the reaction products produced by sequential treatment with acidic fluoride and LaCl3 and powdered apatite glass ceramics are able to effectively occlude dentinal tubules.

Osteoclast differentiation factor acts as a multifunctional regulator in murine osteoclast differentiation and function. (5/1113)Osteoclast differentiation factor (ODF), a novel member of the TNF ligand family, is expressed as a membrane-associated protein by osteoblasts/stromal cells. The soluble form of ODF (sODF) induces the differentiation of osteoclast precursors into osteoclasts in the presence of M-CSF. Here, the effects of sODF on the survival, multinucleation, and pit-forming activity of murine osteoclasts were examined in comparison with those of M-CSF and IL-1. Osteoclast-like cells (OCLs) formed in cocultures of murine osteoblasts and bone marrow cells expressed mRNA of RANK (receptor activator of NF-kappaB), a receptor of ODF. The survival of OCLs was enhanced by the addition of each of sODF, M-CSF, and IL-1. sODF, as well as IL-1, activated NF-kappaB and c-Jun N-terminal protein kinase (JNK) in OCLs. Like M-CSF and IL-1, sODF stimulated the survival and multinucleation of prefusion osteoclasts (pOCs) isolated from the coculture. When pOCs were cultured on dentine slices, resorption pits were formed on the slices in the presence of either sODF or IL-1 but not in that of M-CSF. A soluble form of RANK as well as osteoprotegerin/osteoclastogenesis inhibitory factor, a decoy receptor of ODF, blocked OCL formation and prevented the survival, multinucleation, and pit-forming activity of pOCs induced by sODF. These results suggest that ODF regulates not only osteoclast differentiation but also osteoclast function in mice through the receptor RANK. (+info)
Deficiency of SHP-1 protein-tyrosine phosphatase activity results in heightened osteoclast function and decreased bone density. (6/1113)Mice homozygous for the motheaten (Hcphme) or viable motheaten (Hcphme-v) mutations are deficient in functional SHP-1 protein-tyrosine phosphatase and show severe defects in hematopoiesis. Comparison of femurs from mev/mev mice revealed significant decreases in bone mineral density (0.33 +/- 0.03 mg/mm3 for mev/mevversus 0.41 +/- 0.01 mg/mm3 for controls) and mineral content (1.97 +/- 0.36 mg for mev/mevversus 10.64 +/- 0.67 for controls) compared with littermate controls. Viable motheaten mice also showed reduced amounts of trabecular bone and decreased cortical thickness. These bone abnormalities were associated with a 14% increase in numbers of multinucleated osteoclasts and an increase in osteoclast resorption activity. In co-cultures of normal osteoblasts with mutant or control bone marrow cells, numbers of osteoclasts developing from mutant mice were increased compared with littermate control mice. Although mev/mev osteoclasts develop in the absence of colony-stimulating factor (CSF)-1, nevertheless cultured osteoclasts show increased size in the presence of CSF-1. CSF-1-deficient osteopetrosis (op/op) mutant mice develop severe osteosclerosis. However, doubly homozygous mev/mevop/op mice show an expansion of bone marrow cavities and reduced trabecular bone mass compared with op/op mice. Western blot analysis showed that several proteins that were markedly hyperphosphorylated on tyrosine residues were detected in the motheaten osteoclasts, including a novel 126-kd phosphotyrosine protein. The marked hyperphosphorylation of a 126-kd protein in motheaten osteoclasts suggests that this protein depends on SHP-1 for dephosphorylation. These findings demonstrate that the decreased SHP-1 catalytic activity in me/me and mev/mev mice results in an increased population of activated osteoclasts and consequent reduction in bone density.

Intermittent inhibition of dentin mineralization of rat incisors under continual infusion of 1-hydroxyethylidene-1, 1-bisphosphonate (HEBP) using a subcutaneous mini osmotic pump. (7/1113)The inhibitory effect of the continual administration of 1-hydroxyethylidene-1, 1-bisphosphonate (HEBP) (8 mgP/kg/day) through a mini osmotic pump on dentin mineralization was examined in relation to the diurnal rhythm of the rat and compared with that of daily injections of same amounts of HEBP known to inhibit dentin mineralization. After daily injections of HEBP, a series of alternating rows of mineralized and non-mineralized dentin islands appeared in the newly formed portion of the crown-analogue of rat incisors. A similar phenomenon occurred under the continual administration of HEBP in rats raised either under regular environmental photofraction or constant lighting conditions. The average distance between the adjacent mineralized dentin islands was 521.0 +/- 51.3 microns in the injected rats. After continual HEBP administration, this was 426.0 +/- 13.2 microns and 416.5 +/- 19.4 microns under ordinary photofraction and constant light, respectively. Although the pattern of individual mineralized dentin islands tended to become irregular in nocturnal rats, no statistical difference was noted between the two values. Rows of mineralized and non-mineralized dentin islands also appeared in the root analogue dentin. No sign of the intermittent inhibition of mineralization was recognized in mesodermal hard tissues other than dentin in the HEBP-affected animals. These data implicate the presence of intrinsic cycles in dentin mineralization at the growing end of rat incisors independent of environmental photofraction as well as the ameloblast function.

Interaction between vacuolar H(+)-ATPase and microfilaments during osteoclast activation. (8/1113)Vacuolar H(+)-ATPases (V-ATPases) are multisubunit enzymes that acidify compartments of the vacuolar system of all eukaryotic cells. In osteoclasts, the cells that degrade bone, V-ATPases, are recruited from intracellular membrane compartments to the ruffled membrane, a specialized domain of the plasma membrane, where they are maintained at high densities, serving to acidify the resorption bay at the osteoclast attachment site on bone (Blair, H. C., Teitelbaum, S. L., Ghiselli, R., and Gluck, S. L. (1989) Science 249, 855-857). Here, we describe a new mechanism involved in controlling the activity of the bone-resorptive cell. V-ATPase in osteoclasts cultured in vitro was found to form a detergent-insoluble complex with actin and myosin II through direct binding of V-ATPase to actin filaments. Plating bone marrow cells onto dentine slices, a physiologic stimulus that activates osteoclast resorption, produced a profound change in the association of the V-ATPase with actin, assayed by coimmunoprecipitation and immunocytochemical colocalization of actin filaments and V-ATPase in osteoclasts. Mouse marrow and bovine kidney V-ATPase bound rabbit muscle F-actin directly with a maximum stoichiometry of 1 mol of V-ATPase per 8 mol of F-actin and an apparent affinity of 0.05 microM. Electron microscopy of negatively stained samples confirmed the binding interaction. These findings link transport of V-ATPase to reorganization of the actin cytoskeleton during osteoclast activation. (+info)
Dentin sensitivity is a common dental condition characterized by pain or discomfort in response to stimuli that would not normally cause pain in healthy teeth. The pain is usually felt in the dentin, the layer of the tooth beneath the enamel, and is often described as a sharp, shooting, or burning sensation. Dentin sensitivity can be caused by a variety of factors, including tooth decay, gum recession, tooth grinding or clenching, and exposure of the dentin due to tooth erosion or wear. It can also be triggered by hot or cold beverages, acidic foods and drinks, sweet foods, and brushing too hard or with a harsh toothpaste. Treatment for dentin sensitivity typically involves addressing the underlying cause, such as treating tooth decay or gum disease, and using desensitizing toothpaste or mouth rinses. In some cases, a dentist may recommend a more invasive treatment, such as a dental filling or root canal therapy.
Dentin, secondary, also known as secondary dentin, is a type of dentin that is formed after the primary dentin in the tooth. It is produced by odontoblasts, which are specialized cells that are responsible for forming dentin. Secondary dentin is typically darker in color than primary dentin and has a different microstructure. It is formed in response to injury or inflammation to the tooth and helps to strengthen the tooth and protect it from further damage.
Dentin dysplasia is a rare genetic disorder that affects the development of dentin, the hard, protective layer of the teeth. It is characterized by the abnormal formation of dentin, which can result in teeth that are abnormally thin, weak, and prone to decay. There are two main types of dentin dysplasia: type I and type II. Type I dentin dysplasia is the more common form and is usually inherited in an autosomal dominant pattern, meaning that only one copy of the abnormal gene is needed to develop the condition. Type II dentin dysplasia is less common and is inherited in an autosomal recessive pattern, meaning that both copies of the gene must be abnormal for the condition to develop. Symptoms of dentin dysplasia can vary depending on the severity of the condition. In some cases, affected individuals may have no symptoms at all. However, in more severe cases, symptoms may include sensitivity to hot and cold temperatures, difficulty chewing, and an increased risk of tooth decay and gum disease. In some cases, the condition may also affect the development of other teeth-related structures, such as the jawbone and the roots of the teeth. Treatment for dentin dysplasia typically involves regular dental check-ups and the use of special dental materials to strengthen and protect the teeth. In some cases, more extensive treatment may be necessary, such as the use of dental implants or the extraction of affected teeth.
Methacrylates are a group of organic compounds that contain the -COOR functional group, where R is an alkyl or aryl group. They are commonly used in the medical field as monomers for the synthesis of polymers, such as polymethyl methacrylate (PMMA), which is used in the production of acrylic lenses for glasses and contact lenses. Methacrylates are also used as adhesives, coatings, and sealants in medical devices, such as catheters, implants, and surgical instruments. They have excellent bonding properties and are resistant to water, chemicals, and heat, making them ideal for medical applications. In addition, some methacrylates, such as 2-hydroxyethyl methacrylate (HEMA), are used as solvents for drugs and other medical compounds. HEMA is also used as a monomer in the production of hydrogels, which are used in contact lenses and drug delivery systems. However, some methacrylates, such as bisphenol A dimethacrylate (Bis-GMA), have been associated with potential health risks, including allergic reactions and genotoxicity. Therefore, the use of methacrylates in medical devices and applications must be carefully evaluated to ensure their safety and efficacy.
Resin cements are dental materials that are used to bond dental restorations, such as fillings, crowns, and bridges, to the tooth structure. They are made from a combination of resin monomers, polymers, and other ingredients that are cured with light or heat to form a strong, durable bond. Resin cements are preferred over traditional dental cements because they have a number of advantages, including: 1. Improved adhesion: Resin cements bond to both tooth structure and dental restorations, providing a stronger and more durable bond than traditional cements. 2. Better esthetics: Resin cements can be matched to the color of the tooth, providing a more natural-looking restoration. 3. Increased strength: Resin cements are stronger than traditional cements, which can reduce the risk of fractures and other types of damage to the tooth. 4. Faster curing: Resin cements can be cured in just a few seconds, which can reduce the time required for dental procedures. Overall, resin cements are a popular choice for dental restorations because of their improved adhesion, esthetics, strength, and curing time.
In the medical field, a smear layer is a thin layer of debris and bacteria that forms on the surface of dental tissues, such as teeth and gums, after a cleaning or scaling procedure. This layer can interfere with the bonding of dental materials, such as fillings or crowns, to the underlying tooth structure, and can also contribute to the development of dental plaque and gum disease. To remove the smear layer, dentists may use a variety of techniques, such as polishing or etching, to roughen the surface of the tooth and improve the adhesion of dental materials.
In the medical field, composite resins are a type of dental filling material that is used to restore teeth that have been damaged by decay or trauma. They are made up of a mixture of glass particles and a resin binder, and are often used to fill small to medium-sized cavities. Composite resins are popular among dentists because they are tooth-colored, which means they can be matched to the natural color of the patient's teeth. This makes them an attractive option for patients who want to restore their teeth without the use of metal fillings. In addition, composite resins are relatively easy to use and can be shaped and polished to blend in with the surrounding teeth. While composite resins are generally considered safe and effective, they may not be suitable for all patients. For example, they may not be a good choice for patients who grind their teeth or who have a high risk of developing cavities. In these cases, other types of dental fillings, such as amalgam or gold, may be a better option.
Phosphoric acids are a group of acids that contain the -PO4 group in their molecular structure. They are commonly used in the medical field as a component of various medications and medical treatments. One of the most common uses of phosphoric acids in medicine is as an ingredient in certain types of antacids. Phosphoric acid can help to neutralize stomach acid and reduce symptoms of heartburn and indigestion. Phosphoric acids are also used in some medications to treat kidney stones. They work by increasing the amount of urine produced, which can help to flush out small kidney stones. In addition, phosphoric acids are used in some wound care products to help prevent infection and promote healing. They can also be used as a preservative in some medications to help extend their shelf life. Overall, phosphoric acids play an important role in the medical field as a component of various medications and treatments. However, it is important to note that they can also have side effects and may not be suitable for everyone. It is always best to consult with a healthcare professional before using any medical product containing phosphoric acid.
Tooth demineralization is a process in which minerals in tooth enamel are gradually lost due to exposure to acidic substances, such as sugary drinks, fruit juices, and certain foods. This loss of minerals weakens the tooth structure and can lead to the development of cavities, also known as dental caries. Tooth demineralization can occur at any age, but it is most common in children and adolescents who are still developing their permanent teeth. It can also occur in adults who have poor oral hygiene or who consume a diet high in sugar and acidic foods and beverages. Treatment for tooth demineralization typically involves the use of fluoride toothpaste, mouth rinses, and professional dental cleanings to remineralize the tooth and prevent further decay. In more severe cases, dental fillings or other restorative procedures may be necessary.
Bisphenol A-Glycidyl Methacrylate (Bis-GMA) is a chemical compound that is commonly used as a monomer in the production of dental composite resins, which are used to fill cavities in teeth. Bis-GMA is a type of bisphenol, which is a group of industrial chemicals that are used to make a variety of products, including plastics, resins, and coatings. Bis-GMA is a colorless, odorless liquid that is used in the production of dental composite resins because it can be easily polymerized (combined with other molecules) to form a hard, durable material that can be shaped to fit the contours of a tooth. However, some studies have suggested that Bis-GMA may have potential health effects, including the ability to mimic the effects of estrogen in the body and to cause allergic reactions in some people. As a result, the use of Bis-GMA in dental composite resins has been the subject of some debate and controversy in the medical field.
Dental leakage refers to the passage of bacteria or other microorganisms from the oral cavity into the surrounding tissues or the bloodstream through gaps or spaces in dental restorations, such as fillings, crowns, or bridges. This can lead to the development of dental caries (cavities) or other infections, and can also increase the risk of systemic infections, such as endocarditis or meningitis. Dental leakage can occur due to a variety of factors, including poor fit of the restoration, inadequate cleaning and maintenance, or the presence of cracks or defects in the restoration material. It is important to detect and treat dental leakage promptly to prevent further complications.
Dental caries, also known as tooth decay, is a common dental disease that affects the hard tissues of the teeth, including the enamel, dentin, and pulp. It is caused by the demineralization of tooth enamel due to the production of acid by bacteria in the mouth. The bacteria in the mouth feed on sugars and starches in the food we eat, producing acid as a byproduct. This acid can erode the enamel on the teeth, leading to the formation of cavities. If left untreated, dental caries can progress and cause damage to the underlying dentin and pulp, leading to pain, infection, and tooth loss. Dental caries is a preventable disease through good oral hygiene practices, such as brushing and flossing regularly, using fluoride toothpaste and mouthwash, and limiting sugary and acidic foods and drinks. Early detection and treatment of dental caries can help prevent more serious complications and maintain good oral health.
Sialoglycoproteins are a type of glycoprotein that are found in the saliva of humans and other animals. They are composed of a protein core and one or more carbohydrate chains attached to the protein. Sialoglycoproteins play important roles in a variety of biological processes, including the lubrication and protection of the oral mucosa, the breakdown of food in the mouth, and the immune response. They are also involved in the development and progression of certain diseases, such as cancer and autoimmune disorders. In the medical field, sialoglycoproteins are often studied as potential biomarkers for these and other conditions.
Tooth attrition is the gradual wearing down of the tooth enamel and dentin caused by normal tooth-to-tooth contact during chewing, grinding, or clenching. It is a natural process that occurs throughout a person's life, and it can be accelerated by factors such as bruxism (teeth grinding), acid erosion, and aging. Tooth attrition can lead to a variety of dental problems, including sensitivity, cracking, and even tooth loss. It can also affect the shape and size of the teeth, which can impact the way they fit together and affect the function of the jaw. In some cases, tooth attrition may require dental treatment, such as tooth crowns, fillings, or root canal therapy. Preventive measures, such as wearing a mouthguard during sports or sleep, can also help to reduce the risk of tooth attrition.
Polymethacrylic acids are a type of polymer that are commonly used in the medical field for a variety of applications. They are typically synthesized from methacrylic acid, which is a monomer that can be polymerized to form a long chain of repeating units. Polymethacrylic acids are known for their ability to form gels and hydrogels, which are materials that can absorb and retain large amounts of water. In the medical field, polymethacrylic acids are often used as drug delivery systems. They can be used to encapsulate drugs and release them slowly over time, which can help to improve the effectiveness and duration of treatment. They can also be used as wound dressings, as they can absorb and retain fluids and help to protect the wound from infection. Additionally, polymethacrylic acids have been used in tissue engineering applications, as they can be used to create scaffolds that can support the growth and development of new tissue.
Extracellular matrix (ECM) proteins are a diverse group of proteins that are secreted by cells and form a complex network within the extracellular space. These proteins provide structural support to cells and tissues, regulate cell behavior, and play a crucial role in tissue development, homeostasis, and repair. ECM proteins are found in all tissues and organs of the body and include collagens, elastin, fibronectin, laminins, proteoglycans, and many others. These proteins interact with each other and with cell surface receptors to form a dynamic and highly regulated ECM that provides a physical and chemical environment for cells to thrive. In the medical field, ECM proteins are important for understanding the development and progression of diseases such as cancer, fibrosis, and cardiovascular disease. They are also used in tissue engineering and regenerative medicine to create artificial ECMs that can support the growth and function of cells and tissues. Additionally, ECM proteins are used as diagnostic and prognostic markers in various diseases, and as targets for drug development.
Dental pulp exposure is a condition in which the innermost layer of the tooth, called the dental pulp, becomes exposed or damaged. The dental pulp contains nerves, blood vessels, and connective tissue that nourish and support the tooth. When the pulp is exposed, it can become infected, inflamed, or painful, and may require treatment to prevent further damage or infection. Causes of dental pulp exposure can include tooth decay, trauma, or dental procedures such as root canal therapy or tooth extraction. Treatment options for dental pulp exposure may include pain management, antibiotics, or a procedure called pulpotomy or pulpectomy, in which the damaged pulp is removed and the tooth is filled and sealed to prevent further infection.
Dentinogenesis Imperfecta (DI) is a group of inherited disorders that affect the development and structure of tooth enamel and dentin, the two main components of teeth. DI is characterized by abnormal tooth formation, which can result in teeth that are weak, brittle, and prone to fracture. The severity of DI can vary widely, ranging from mild to severe, and can affect both primary (baby) teeth and permanent teeth. In some cases, DI can also affect the development of bones in the jaw and face. There are several different types of DI, which are classified based on the specific genetic mutations that cause them. Treatment for DI typically involves managing the symptoms and complications of the condition, such as tooth decay and fractures, and may also include dental procedures to improve the appearance and function of affected teeth.

Sodium hypochlorite is available in various concentrations and is typically mixed with water to form a solution for use. It is important to handle sodium hypochlorite with care, as it can be harmful if ingested or inhaled in large quantities.
Tooth erosion is a dental condition that occurs when the hard outer layer of the tooth, called the enamel, is worn away by acids. This can happen due to various factors, including exposure to acidic foods and drinks, frequent vomiting or regurgitation, certain medical conditions, and certain habits such as teeth grinding or clenching. Tooth erosion can cause a number of problems, including sensitivity to hot and cold, difficulty chewing, and an unattractive appearance of the teeth. In severe cases, it can lead to tooth decay and even tooth loss. Treatment for tooth erosion depends on the severity of the condition. In mild cases, simply changing one's diet and avoiding acidic foods and drinks may be enough to slow or stop the erosion. In more severe cases, a dentist may recommend fluoride treatments, dental bonding, or other restorative procedures to repair the damaged teeth.
In the medical field, water is a vital substance that is essential for the proper functioning of the human body. It is a clear, odorless, tasteless liquid that makes up the majority of the body's fluids, including blood, lymph, and interstitial fluid. Water plays a crucial role in maintaining the body's temperature, transporting nutrients and oxygen to cells, removing waste products, and lubricating joints. It also helps to regulate blood pressure and prevent dehydration, which can lead to a range of health problems. In medical settings, water is often used as a means of hydration therapy for patients who are dehydrated or have fluid imbalances. It may also be used as a diluent for medications or as a component of intravenous fluids. Overall, water is an essential component of human health and plays a critical role in maintaining the body's normal functions.
Tooth abrasion is a dental condition that occurs when the outer layer of the tooth, called the enamel, is worn down or abraded. This can happen due to various factors, including brushing too hard, using a toothbrush with hard bristles, grinding or clenching teeth, consuming acidic foods and drinks, and chewing on hard objects such as ice or pencils. Tooth abrasion can cause a number of symptoms, including tooth sensitivity, pain when chewing, and a rough or uneven tooth surface. In severe cases, it can lead to tooth decay, gum recession, and even tooth loss. Treatment for tooth abrasion typically involves addressing the underlying cause, such as changing brushing habits or using a softer toothbrush. In some cases, a dentist may also use a fluoride treatment or a dental filling to help protect the tooth and prevent further damage.
Glutaral is a colorless, crystalline compound that is a derivative of glutaric acid.

Tooth fractures refer to the partial or complete breakage of the hard outer layer of a tooth, known as the enamel. Tooth fractures can occur as a result of trauma, such as a blow to the face, or from excessive force applied to the tooth during biting or chewing. There are several types of tooth fractures, including: 1. Fractures of the enamel: These occur when the outer layer of the tooth is broken, but the underlying dentin and pulp are not affected. 2. Fractures of the dentin: These occur when the dentin, the layer of tooth beneath the enamel, is broken. 3. Fractures of the pulp: These occur when the innermost layer of the tooth, the pulp, is damaged. 4. Complete tooth fractures: These occur when the entire tooth is broken into two or more pieces. Tooth fractures can cause pain, sensitivity, and difficulty chewing or speaking. Treatment options depend on the severity of the fracture and may include filling the tooth, root canal therapy, or extraction and replacement with a dental implant or bridge.
Pulpitis is a medical term used to describe inflammation of the pulp, which is the soft tissue inside the tooth that contains nerves, blood vessels, and connective tissue. Pulpitis can be acute or chronic, and it can be caused by a variety of factors, including tooth decay, injury, or infection. Acute pulpitis is a sudden and severe form of pulpitis that is often accompanied by sharp, shooting pain that can be triggered by hot or cold temperatures, pressure, or sweet or sour foods. Chronic pulpitis is a less severe form of pulpitis that may cause dull, aching pain that is relieved by over-the-counter pain medication. If pulpitis is left untreated, it can lead to the formation of an abscess, which is a pocket of pus that can cause further pain and infection. Treatment for pulpitis typically involves root canal therapy, which involves removing the inflamed pulp and cleaning and sealing the inside of the tooth. In some cases, a tooth may need to be extracted if it is too damaged to save.

These techniques allow researchers to identify and quantify the phosphorylation status of specific proteins in cells and tissues, and to study the effects of changes in phosphorylation on protein function and cellular processes.
Root caries, also known as root decay or tooth decay on the root surface, is a type of dental caries (cavities) that occurs on the root surfaces of teeth. Unlike the more common type of dental caries that occurs on the chewing surfaces of teeth, root caries typically affects older adults and is more common in people with certain medical conditions, such as diabetes or osteoporosis. Root caries can cause pain, sensitivity, and difficulty chewing or speaking. It can also lead to tooth loss if left untreated. Treatment for root caries typically involves removing the decayed tissue and filling the cavity with a dental filling material. In some cases, root canal therapy may be necessary to save the tooth. Good oral hygiene, including regular brushing and flossing, can help prevent root caries.
Tooth wear is a common dental condition that refers to the gradual loss of tooth structure due to various factors. It can occur on the surface of the tooth or extend deeper into the tooth structure, affecting the shape, size, and function of the tooth. There are several types of tooth wear, including: 1. Attrition: This is the most common type of tooth wear, which occurs when the tooth surfaces rub against each other, causing the enamel and dentin to wear down. 2. Abrasion: This type of tooth wear occurs when the tooth surface is worn down by external factors such as brushing too hard, grinding teeth, or consuming acidic foods and drinks. 3. Erosion: This type of tooth wear occurs when the tooth surface is worn down by chemical factors such as acid reflux, stomach acid, or frequent exposure to acidic foods and drinks. Tooth wear can cause a variety of dental problems, including sensitivity, pain, difficulty chewing, and even tooth loss. Treatment options for tooth wear depend on the severity of the condition and may include dental bonding, dental crowns, or dental veneers.

Integrin-Binding Sialoprotein (IBSP) is a protein that plays a role in bone formation and remodeling. It is also known as osteoblast-specific factor 2 (OSF-2) or bone sialoprotein (BSP). IBSP is synthesized by osteoblasts, which are cells responsible for forming new bone tissue, and is secreted into the extracellular matrix where it binds to integrins, which are cell surface receptors that mediate cell adhesion and migration. IBSP has been shown to regulate bone mineralization, cell proliferation, and differentiation, and is involved in the formation of the dentin matrix in teeth. It is also expressed in other tissues, including the placenta, lung, and kidney, where it may play a role in tissue development and repair.
Fluorides are compounds that contain the fluoride ion (F-). In the medical field, fluorides are commonly used to prevent tooth decay and improve oral health. They can be found in a variety of products, including toothpaste, mouthwashes, and fluoride supplements. Fluoride works by strengthening tooth enamel, making it more resistant to acid attacks from bacteria in the mouth. It can also help to remineralize tooth enamel that has already been damaged by acid. Fluoride is also used in water treatment to reduce the risk of tooth decay in communities. In addition, fluoride is sometimes used in dental procedures, such as fluoride varnishes and fluoride gels, to further strengthen teeth and prevent decay. While fluoride is generally considered safe and effective, excessive exposure to fluoride can lead to dental fluorosis, a condition that causes white or brown stains on the teeth. It is important to use fluoride products in moderation and to follow the instructions on the label.
