目的:了解目前我国城市地区18~69岁成人牙本质敏感的患病状况及相关影响因素，观察我国牙本质敏感的患病状况和分布的变化趋势。方法:调查对象为北京、上海、武汉、成都、西安、广州和哈尔滨共7个城市地区18~69岁城市居民，采用多阶段、分层、等容量随机抽样的方法进行抽样，对样本人群进行牙本质敏感相关的问卷调查和口腔检查，调查预计半年内完成。通过问卷了解被调查人群的人口社会学因素、饮食情况、口腔卫生习惯和个人病史。牙本质敏感的诊断结合受检者的自我感觉和冷空气喷吹敏感检查，临床采用Schiff牙本质敏感计分评判敏感程度。统计除哈尔滨以外六城市地区牙本质敏感的患病状况，并与2008年的调查结果进行比较。结果:本次调查自2021年3月至2023年5月开展，共计11 622名18~69岁成人受试者完成问卷调查和口腔检查。52.2%（6 072/11 622）的受检者自述有牙齿敏感症状，临床检查调查人群牙本质敏感患病率为36.7%（4 266/11 622）。年龄、性别、生活地区、刷牙方法和返酸病史与牙本质敏感的发生有关（ P<0.05）。除哈尔滨以外六城市地区牙本质敏感患病率为33.7%（3 335/9 882），高于2008年牙本质敏感患病率的调查结果［29.7%（2 354/7 939）］。 结论:牙本质敏感在我国城市地区18~69岁成人中很普遍，且牙本质敏感患病率近年显著上升，口腔专业人员需要重视牙本质敏感的防治。

Objective:To assess the prevalence of dentinal hypersensitivity (DH) and related factors in urban adults in China.Methods:The study was designed as an observational, cross-sectional epidemiological study carried out in adults aged 18-69 years old in seven cities (Beijing, Shanghai, Wuhan, Chengdu, Xi′an, Guangzhou, and Harbin) of China. Patients were required to complete a questionnaire regarding the subjects′ socio-economic factors, dietary behavior, oral health behavior and personal antecedent factors. DH was clinically diagnosed by judging whether the tooth cold air stimulation provoked DH or not, and recorded by investigator pain rating Schiff score. Compare the findings of six cities (Harbin excluded) with a similar study conducted in 2008.Results:The study was conducted from March 2021 to May 2023, and 11 622 subjects from seven cities in China participated the study in total. Fifty two point two percent (6 072/11 622) of subjects reported DH in questionnaire, 36.7% (4 266/11 622) of subjects reported experiencing DH in response to cold air stimulation for at least one study tooth. Risk factors including age, sex, city, toothbrush method and acid reflux showed marked associations with DH ( P<0.05). The prevalence of DH of urban residents in six cities (Harbin excluded) was 33.7% (3 335/9 882), higher than that in 2008 [29.7%(2 354/7 939)]. Conclusions:Overall, DH was common among urban adults in China and the prevalence increased in recent years. Better understanding of DH and its associated factors should be considered in its prevention and management by dental professionals.
