To carry out a cross-sectional study of the prevalence of dentine hypersensitivity and related risk factors in Chengdu City, China.
A total of 1,320 subjects were distributed equally in six communities in Chengdu City and of all age groups (10 years for an age group) including the same number of male and female subjects in each community. Each subject completed a structured interview and the subjects who reported hypersensitivity were examined further using a triple syringe to administer a blast of cold air to confirm the diagnosis of dentine hypersensitivity. Periodontal attachment loss and gingival recession of all sensitive teeth were measured.
The prevalence of dentine hypersensitivity was 25.5% in the oral test. Only 16.6% of subjects who reported hypersensitivity symptoms had received desensitising treatment. 50-59 year age group was the cohort with the greatest number of subjects with DH and the premolar was the most commonly affected tooth. Low education level, gingival recession, and attachment loss were related to dentine hypersensitivity.
The prevalence of dentine hypersensitivity in an urban adult population in Chengdu City was 25.5%.
在中国成都市进行横断面研究，调查牙本质敏感的流行情况及其相关危险因素。
将 1320 名受试者平均分配到成都市的 6 个社区，年龄组为 10 岁，每个社区的男女受试者人数相同。每位受试者完成一份结构式访谈，报告有敏感症状的受试者进一步使用三用注射器喷射冷空气以确认牙本质敏感的诊断。测量所有敏感牙齿的牙周附着丧失和牙龈退缩。
口腔测试中牙本质敏感的患病率为 25.5%。仅 16.6%报告有敏感症状的受试者接受了脱敏治疗。50-59 岁年龄组是 DH 患者数量最多的队列，前磨牙是最常受影响的牙齿。低教育水平、牙龈退缩和附着丧失与牙本质敏感有关。
成都市成年城市人口中牙本质敏感的患病率为 25.5%。
