Enamel, the shiny material covering the teeth of vertebrates is the hardest tissue the vertebrate body can produce and one of the most impressive products of biomineralization. This hard tissue is closely related to feeding, the first part in the energy intake process so basic to vertebrate life. Enamel has a complex internal microstructure full of phylogenetic and biomechanic information. Topics covered: Ontogeny; Crystallite level; Prism level; Enamel type level; Schmelzmuster level; Dentition level; Evolution; Biomechanical level; Glossary.

A survey of the enamel microstructure of 43 reptilian taxa reveals great structural variety and complexity. With the exception of the agamid lizard Uromastyx, all taxa have enamel without prisms. Reptilian enamel is thus not comparable to that of the Mammalia. The development of a new terminology was necessary to describe reptilian enamel and to address questions of functional vs. phylogenetic constraints on its microstructure. This new terminology was developed using a similar approach to one developed for mammalian enamel. It is hierarchical and free of amelogenetic or phylogenetic connotations. Starting at the smallest structures, five levels of complexity are recognized: crystallite level, module level, enamel type level, schmelzmuster level, and dentition level. Detailed microstructural analysis of the 43 taxa using the new terminology indicates that phylogenetic constraints are of little significance. Only two higher taxa, advanced ornithopod dinosaurs and the Ichthyosauria, show distinctive enamel synapomorphies. Biomechanical constraints on the internal structure of reptilian enamel are even more difficult to discern. The major factor determining microstructure is enamel surface morphology, i.e. the ridges and wrinkles on the surface of many teeth which presumably are adaptive. Reptilian amelogenesis is largely responsible for the creation of this morphology as the boundary plane between the dentin and the enamel (the EDJ) is smooth and not ridged or wrinkled. The concept of amelogenesis as enamel surface morphogenesis is best illustrated by a comparison of durophagous reptiles. Numerous unrelated groups convergently evolved the typical bulbous tooth shape but each group has an autapomorphic enamel microstructure. Other ecomorphotypes such as ziphodont carnivores exhibit convergent evolution of enamel microstructure. The structures observed raise important questions about reptilian amelogenesis. There certainly is no one-to-one correspondence between structural units and the ameloblast matrix as opposed to the situation in mammals. Such a correspondence has been assumed in the current models of the evolutionary origins of mammalian enamel prisms, and its absence invalidates these models.

In this field there has been an explosion of information generated by scientific research. One of the beneficiaries of this has been the study of morphology, where new techniques and analyses have led to insights into a wide range of topics. Advances in genetics, histology, microstructure, biomechanics and morphometrics have allowed researchers to view teeth from alternative perspectives. However, there has been little communication between researchers in the different fields of dental research. This book brings together overviews on a wide range of dental topics linking genes, molecules and developmental mechanisms within an evolutionary framework. Written by the leading experts in the field, this book will stimulate co-operative research in fields as diverse as paleontology, molecular biology, developmental biology and functional morphology.

This book gives an introduction to the mechanical behavior and degradation of dental ceramics and guides the reader through their performance under effect of oral environments. It addresses the different kinds of dental ceramics, their properties, degradation and mechanical aspects with less emphasys on the physics and chemistry involved, which makes the reading interesting for beginners in the field. In each chapter, the reader will learn about the mechanical behavior of dental ceramics and each phenomenon involved in their application, besides finding some practical examples of their use in dental clinics, their manufacturing procedures and types of degradation. The clear language and the application-oriented perspective of the book makes it suitable for both professionals and students who want to learn about dental ceramics.

Defective development of tooth enamel or dentin is a significant dental problem for children and adolescents in various respects, and dentists and other oral health workers find managing these problems challenging and stressful. While a considerable amount of relevant research is currently being undertaken, much further investigation is needed. This book discusses the known causes of defective dental enamel and explains why it is so difficult to restore. Most importantly, it presents the signs and symptoms that allow accurate diagnosis and documents the best contemporary management. The full range of enamel defects is considered, including defects in primary teeth and permanent teeth, associated syndromes, molar incisor hypomineralization, and genetic defects. The clinical chapters are well illustrated, providing clear guidelines for each procedure. In addition, avenues for future research are identified, with explanation of their rationale.

"Tooth Enamel: Frontiers in Mineral Chemistry and Biochemistry, Integrative Cell Biology and Genetics" incorporates the proceedings of the 9th International Enamel Symposium (Enamel 9) hosted in the UK and chaired by Professor Jennifer Kirkham and Professor Ariane Berdal. The topic covers cellular and molecular aspects of the development, pathology, evolution and repair or regeneration of dental enamel. The original research papers and reviews will be of interest to all enamel and biomineralization researchers. Clinicians will find up-to-date thinking and opinion on the aetiology of enamel pathologies and their potential future treatment via novel strategies for preventing, repairing and regenerating enamel.
