To investigate the prevalence of dentin hypersensitivity in Chinese urban adults aged between 20 - 69 years old and the factors related to dentin hypersensitivity. The Chinese national survey on dentin hypersensitivity was conducted in 20 - 69 years old adults in six representative cities, Beijing, Shanghai, Guangzhou, Wuhan, Chengdu, and Xi'an in 2008. A multi-stage stratified randomizing sampling method was used. Subjects were recruited from 36 urban survey sites in 6 cities. A structured questionnaire and a clinical examination on dentin hypersensitivity were used in the survey. The dentin hypersensitivity was diagnosed by a subject self-perceived short, sharp pain in response to a blast of cold air from a triple syringe administered to a tooth surface in 1 cm. In total, 7939 twenty to sixty-nine years old subjects completed a structured interview and underwent a clinical examination on dentin hypersensitivity. Among them, 40.7% (3230/7939) of the subjects reported being suffered from teeth sensitivity. Wh
