Collagen is the most abundant protein in the human body and is necessarily part of the structural connective tissue in every bodily organ. A knowledge of the biosynthesis and structure of collagen and its interactions with other non-collagenous proteins is therefore seen as essential to the understanding of the functioning of these organs. Information on the specific arrangements of the various collagens in individual dental tissues leads to an understanding of age-related changes or alterations that may occur as a result of disease. Apart from enamel, all dental diseases involve collagenous matrices. Currently known information on collagen present in the oral environment are brought together here; its biosynthesis, structure and interrelationship with its known non-collagenous componenets are all considered in detail. This book is intended for use as a reference work for undergraduate and postgraduate students and for all those involved in basic dental research.
