Download or read book Ultrastructural Changes in Edta Treated Dental Enamel written by Seymour Hoffman and published by . This book was released on 1969 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Enamel samples treated with EDTA for 2, 4, 7, and 24 hours respectively were examined with the SEM and compared to the appearance of sound, untreated enamel. It was apparent that the EDTA demineralized the rods from their peripheral borders centrally, thus progressively delineating these structures. A variety of prism forms were described, with the 'keyhole' and arcade variants predominating. Hexagonal and polygonal forms were not seen. Interprismatic material could not be positively identified. The prism-less zone and its reported crystallite orientation was supported by the findings in this study. Enamel rods from the striae of Retzius were studied and compared with those from intervening regions. Significantly fewer crystallites were present in prisms from the striae than from the adjacent contiguous areas, thus providing additional support that this region may represent an area of hypomineralization. Progressive loss of surface coatings by EDTA action were demonstrated revealing what appeared to be sub-surface continuity with prism sheaths and intercrystalline material. (Author).

Download or read book Tooth Enamel Ultrastructure written by Hazem Eimar and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Tooth enamel is one of the hardest materials found in the animal kingdom. Accordingly, understanding its unique characteristics is of special interest for the interpretation of distinct tooth physical properties and for the development of new synthetic materials. Enamel is a composite material that comprises an inorganic matrix composed of hierarchically organized carbonated hydroxyapatite (HA) crystals, and an organic matrix mainly composed of the protein amelogenin. This study was designed to investigate how variations in enamel ultrastructure and chemical composition (organic and inorganic) may affect tooth mechanical and optical properties.One hundred extracted sound teeth were collected from adult patients attending McGill Undergraduate Dental Clinic. Vickers microindentation, Shade spectrophotometry, FTIR, SEM-EDS and XRD were used to asses enamel microhardness, tooth shade (registered in universal shade parameters: lightness, chroma and hue), chemical ....

Download or read book Tooth Whitening written by Jorge Perdigão and published by Springer. This book was released on 2016-08-03 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the evidence relating to the mechanisms, clinical efficacy, safety/toxicity, and clinical application of tooth whitening techniques and materials. All clinical techniques are profusely illustrated step by step. The book is divided into four parts, the first of which explains how tooth whitening with peroxides works and examines the overall safety of peroxides and potential complications. The findings of clinical trials with peroxide-based materials for clinical practice are then examined, with discussion of a wide range of issues in at-home whitening and in-office whitening. The third part focuses on the techniques of enamel microabrasion and resin infiltration, which entail removal of a microscopic layer of enamel and may be used to improve tooth color either alone or in combination with peroxides. The concluding part includes a variety of informative clinical cases using combined bleaching and restorative techniques for discolored teeth. Tooth Whitening — An Evidence-Based Perspective will be of interest for dentists, dental hygienists, dental assistants, and others with an interest in the subject

Download or read book Surface Reactivity of Tooth Enamel with Dyes Oxidizing Agents and Magnesium Ions and Its Effect on Tooth Color written by Mohamed Nur Abdallah and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Enamel, the outer protective layer of human teeth, is constantly interacting with its surrounding harsh environment. These interactions play a major role in many mechanisms that affect the dental health such as tooth caries, tooth discoloration and plaque formation. Accordingly, most treatments used to maintain and/or restore dental health focus first on the enamel surface. Even though most of the enamel structure has been thoroughly studied, many of the enamel surface features, and the chemical reaction that occur on it, are not well understood. Extrinsic tooth discoloration poses a major problem to many patients and dentists. Most causes of extrinsic tooth staining have been well identified and are usually treated with hydrogen peroxide. However, the mechanism of extrinsic tooth discoloration and tooth bleaching using peroxide oxidizers are not fully understood. It is unknown why certain staining molecules attach to the enamel surface, whether peroxide radicals make teeth whiter by removing these stains, and why sometimes hydrogen peroxide does not work. Also, treating darkened teeth with peroxide agents has its limitations and disadvantages. This has pushed us to look for better and less harmful whitening agents. Recent studies have revealed that there is a correlation between crystallographic characteristics of enamel and its physical properties, such as tooth shade and microhardness. This discovery predicts that tooth properties can be changed by modifying its crystallographic structure. Since magnesium ions are known to react with synthetic hydroxyapatite and affect its crystallographic properties, it is possible that magnesium ions could react with dental enamel and induce changes in dental enamel crystallographic, optical and mechanical properties. Several significant conclusions and achievements are presented in this thesis. We demonstrated the presence of a carbon rich layer on the surface of enamel that contains relatively high amounts of calcium. This layer might explain the high staining ability of certain types of anionic staining agents that are among the most common causes of external tooth discoloration. Moreover, we showed that hydrogen peroxide does not induce significant changes in tooth enamel organic and inorganic relative contents, and it whitens teeth just by oxidizing their organic matrix. This finding is of great clinical significance since it explains the mechanism of tooth bleaching and the reasons behind the limited predictability of the treatment outcomes. Finally, we showed for the first time that magnesium ions can react with tooth enamel and induce a reduction in the size of enamel hydroxyapatite nanocrystals. This change in crystallography affected the enamel optical and mechanical properties; making the enamel harder and whiter. This is a new method that can be exploited to whiten teeth without using peroxide-based bleaching agents. We concluded that crystallographic ultrastructure plays a key role in defining the tooth enamel properties which can be tailored through ionic substitution for improvement of optical and mechanical properties without causing the possible negative effects of peroxide agents." --
