Abstract Background: As far as we know, little data, whether obtained from self-administered questionnaires or upon dental clinical examination, has been published on the prevalence of sensitive teeth (ST) in the French adult population. The objectives of the present work were to estimate ST prevalence and characteristics in the general population of France and to explore the associated factors. Method: A multicentre cross-sectional study was conducted between November 2011 and March 2013 in six French cities. Adult passers-by in public places were invited to answer an electronic questionnaire on a tablet computer. Only people who declared having at least one natural tooth were included in the study. A logistic regression model was used for the multivariate analysis. Results: The prevalence of ST during the previous 12 months reported by the sample of 2413 participants was 42.2% [95% CI: 40.2–44.1%]. The final logistic regression model showed significant statistical associations between ST and female gender, use of tobacco, consumption of soft drinks, limited access to oral care and poor oral hygiene habits (p < 0.05). Conclusions: This study provides prevalence data on ST in a general population in France, which seems to remain high despite the existence of many therapies. It should alert professionals to a clinical manifestation that is becoming increasingly prevalent and that they will have to take into consideration to help reduce the discomfort arising from it.

Background Dentin hypersensitivity (DH) is a frequently recurring finding and a challenging condition to treat in clinical practice [1–3]. DH is characterized by an acute, transient pain from an area of exposed dentin, in response to stimuli that cannot be attributed to any other form of defect or disease. The stimulus is usually thermal, * Correspondence: [email protected] 1 Dental Public Health Department, University of Lille, Faculty of Dentistry, Lille, France 2 Collège National des chirurgiens-dentistes universitaires en santé publique (CNCDUSP) -French Society for Dental Public Health, Toulouse, France Full list of author information is available at the end of the article
chemical, tactile, osmotic, or even related to evaporation (air jet) [2, 4]. Theories concerning the mechanisms of pain conduction inside the dentin are various and controversial. The hydrodynamic theory, developed in 1962 by Brännström, proposes the most commonly accepted explanation for this painful phenomenon [4, 5]. The activation of intrapulp nerve fibres is thought to result fr
