Introduction and Overview: Statement of the Problem

This chapter provides an introduction to this book by briefly describing and discussing the current knowledge on specific aspects of dentine hypersensitivity (DH). Prevalence and distribution data are summarised. An internationally agreed definition is presented together with discussion on alternative terminology. The hydrodynamic mechanism of dentine sensitivity as applying to DH is described and what probable aetiological factors involved in the development of the problem and any subsequent activation of the mechanism is discussed. A secondary preventive-based management programme is proffered, and treatment approaches are discussed. Finally, some present-day deficiencies in knowledge of the condition are identified, and suggestions for future research are made.
