This book, now in an extensively revised second edition, provides wide-ranging information on the progress achieved in the diagnosis, treatment, and management of dentine hypersensitivity during the past few years. Recent advances in research, including innovations in the development of desensitizing agents, are fully described and detailed attention is paid to novel clinical approaches and potential future strategies in product development. Introductory chapters cover important aspects of physiology, prevalence and aetiology and advances in diagnosis and in vitro testing techniques for dentine hypersensitivity are discussed. Dentine hypersensitivity is a troublesome clinical condition that continues to perplex the clinician despite the vast array of available treatments that have been formulated to resolve the problem. There continues to be under-reporting of the condition by clinicians and uncertainty over aetiology, diagnosis, and effective management. This book will hopefully contribute to combating these deficiencies and assist the clinician in delivering optimal patient care.
