Dentine hypersensitivity and associations with self-reported oral health and quality of life data in seven European countries.

Objectives To examine clinically-assessed dentine hypersensitivity and its associations with self-reported oral health and quality of life data.Methods A cross-sectional, observational, epidemiological study in healthy adults in seven European countries was undertaken. Participants underwent a clinical oral examination which assessed dentine hypersensitivity (DH) using an evaporative air stimulus with clinician reported Schiff scale and participant reported binary (yes/no) scores, gingival recession (GR), erosive tooth wear (ETW). Participants also completed a questionnaire on oral health, DH and lived experience.Results A total of 3,551 participants completed the study, the mean age was 44.0 years (standard deviation 17.4), 56.4% were females, and 29.1% had ≥1 site with Schiff 2/3. DH was more common buccally than lingually (p
