Prevalence of dentine hypersensitivity and study of associated factors: a European population-based cross-sectional study

Excerpt

Dentine hypersensitivity (DH) is a common type of oral pain characterized as an intense, transient pain triggered by exposed dentine being stimulated by various factors. Chemical, thermal, tactile, and osmotic stimuli induce intratubular fluid to flow, leading to the activation of nocioceptors in the pulp–dentine border area. The prevalence of DH ranges from 1.34–98% depending on the population, the different diagnostic criteria used to define DH, and whether the data are based on clinical evaluation or patient-based questionnaires. Although many of the risk factors leading to dentine exposure have been identified, it is not clear which are key. Gingival recession is known to be associated with overzealous oral hygiene habits. A diet high in acid, periodontal disease and its treatment have also been linked to DH. About half of patients experience sensitivity after having undergone scaling and root planing. Younger adults also suffer from DH despite having intact periodontium, as they often consume acidic and erosive foods. Even orange juice has been shown to cause enamel deterioration and opening of the dentine tubules. …
