Pathology of the Hard Dental Tissues

This is a seminal text uniquely dedicated to oral hard tissue pathology, presenting the growth of clinical knowledge and advancement in the field in recent years. Starting with a discussion of numerical and formative anomalies and unusual eruption, the book goes on to consider caries, erosion, resorption and toothwear, as well as tooth fractures and discolouration, and ends with a chapter on congenital syndromes with dental anomalies. Pathology of the Hard Dental Tissues is an invaluable reference for specialist practitioners and researchers as well as dental students, combining a scholarly overview of the field with clinical management protocols. Includes prevention techniques as well as treatment regimes Contains many colour clinical photographs Accompanied by a large number of references Provides helpful tables to categorise the causes and characteristics of lesions Written by a leading expert in the field
