When you are building an oral health treatment plan, one of the best things that you can do is to take steps to preserve as much of your existing health dental structure as possible. Because dental enamel is designed to be strong and resistant to damage, the more that you can do to preserve dental enamel the better it is for your smile.. Today our OFallon dentists are sharing some more information about enamel; we hope that this empowers you to care for your teeth!. Dental enamel is the outermost layer of your smile. Every tooth is actually comprised of multiple layers: the dental enamel, the dentin, and then finally the dental pulp. Of these three layers the dental enamel is the least porous and the most durable.. Additionally, dental enamel does not have nerves in it. This is what allows you to chew and drink your favorite beverages without experiencing pain and sensitivity.. In order to maintain strong and healthy dental enamel, you want to make sure that you are drinking plenty of water, ...
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, ...

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 ...

Since childhood, you have seen constant warnings about cavities. Your favorite TV shows likely featured them a few times. You probably learned about them in school, and your dentist probably explained them to you during one of your first checkups.. Luckily, you have never had to experience a cavity before. Your teeth have stayed healthy for years because of your close attention to dental hygiene. However, youve recently noticed some strange spots on your teeth, and you wonder if you have developed a cavity.. Below, we will tell you how to assess whether or not you have one of these dental caries. We will also answer several common questions our patients have about cavities.. 1. What Are Cavities?. The term "cavity" refers to a hole in your teeths enamel. That hole forms because bacteria make the enamel decay. These holes start small at first, and you may not notice them. But as they develop, they can eat away at your enamel until they reach the dentin and pulp underneath. They may even cause a ...
