Overview of the clinical evidence for the use of NovaMin in providing relief from the pain of dentin hypersensitivity.

Dentin hypersensitivity is a common condition that affects the adult population worldwide. NovaMin is technically described as amorphous sodium calcium phosphosilicate, and has been shown in laboratory studies to rapidly occlude dentin tubules and form a protective hydroxyapatite-like layer on the dentin surface. A number of clinical studies investigating the efficacy of NovaMin for the relief of pain from dentin hypersensitivity have been conducted in the United States, Ireland, China, and India.

Construction and validation of the quality of life measure for dentine hypersensitivity (DHEQ).

Aim: To develop and validate a condition specific measure of oral health-related quality of life for dentine hypersensitivity (Dentine Hypersensitivity Experience Questionnaire, DHEQ).

Materials And Methods: Questionnaire construction used a multi-staged impact approach and an explicit theoretical model. Qualitative and quantitative development and validation included in-depth interviews, focus groups and cross-sectional questionnaire studies in a general population (n=160) and a clinical sample (n=108).
