This book was released on 2017-10-19 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Case reports and clinical trials conducted in various countries show, more and more frequently, a positive correlation between the presence of original teeth and prevalence of root caries in older age. Because this is a global trend, it is likely that the predicted increase in the worldwide elderly population may soon cause a significant increase in the number of people requiring effective means of preventing and treating root surface caries. In response to this development, a team of outstanding contributors has reviewed the most important aspects of root caries. This new volume presents their findings along with discussions of how to deal with this health issue that progressively affects the oral health balance. The chapters in this book are divided in four core parts: Epidemiology, Biological Determinants, Lesion Assessment and Features and Preventive and Operative Therapies. The collection of state-of-the-art articles provides a broad overview and will serve as a reference for clinicians as well as scientists and, hopefully, will encourage new research.

As the outermost layer of teeth, enamel is susceptible to caries due to the products of bacteria metabolism; or can be lost by trauma or by non-carious tooth loss resulting from dental erosion, attrition, abrasion or acidic foods. As the enamel lesions progress into dentine, tooth hypersensitivity often develops when the exposed dentine is subjected to stimuli. Traditional treatments include replacing the defected tooth structure with dental restorative materials such as amalgam, composite resin, and ceramics. However, marginal leakage, hypersensitivity and secondary caries often happens at the interface. Therefore, there is a need for scientists to design an alternative strategy to repair the tooth lesions. Biomineralisation process is an organic matrix-mediated non-classical crystallization pathway. Biomimetic mineralisation is concepts from biomineralisation trying to transfer biomineralisation principles to the regeneration of new biomaterials. This study systematically reviewed the laboratory methods on biomimetic mineralisation of demineralised human enamel and dentine, respectively. Many studies reported success in biomimetic mineralisation of enamel and dentine. However, there still exist some problems in the biomimetic mineralisation of enamel and dentine, such as remineralisation conducted under non-physiological conditions, potential contamination in natural protein-guided mineralisation, and the difficulties in reproducing the structural hierarchy of apatite deposition within the collagen matrix. Thus, we aimed to remineralise the demineralised enamel and dentine using biomimetic mineralisation methods. Firstly, we constructed an agarose hydrogel biomimetic mineralisation model to mimic the gel-like microenvironment of initial enamel formation. The tissue generated in this model had enamel prism-like layers containing well-defined hexagonal hydroxyapatite crystals. The modulus of elasticity and the nanohardness of the regenerated enamel prism-like tissue were similar to those of natural enamel. Based on this study, a follow-up study was designed by adding enamel matrix derivative in this agarose hydrogel biomimetic mineralisation model to mimic the organic matrix protein in guiding the formation of enamel prism-like tissue. Enamel matrix derivative promoted in vitro biomimetic mineralisation and facilitated enamel prism-like tissue formation on demineralised human enamel. The regeneration of enamel using this model is a promising approach for the management of enamel loss. Secondly, casein phosphopeptide-amorphous calcium phosphate was applied to the phosphorylated dentine surface to induce the biomimetic mineralisation of dentine collagen fibrils. Casein phosphopeptide-amorphous calcium phosphate could induce intrafibrillar and interfibrillar apatite crystals nucleation and growth along the phosphorylated dentine collagen fibres. We also successfully designed and fabricated a novel oligopeptide to mimic the functions of non-collagenous proteins in the biomineralisation process of dentine. Crystals were observed covering the oligopeptide-coated dentine surface, within the demineralised dentine collagen matrix and occluding dentinal tubules. This oligopeptide can induce biomimetic mineralisation of dentine. Therefore, we concluded that biomimetic mineralisation of enamel and dentine is a potential

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." --
