我国城市地区成人牙本质敏感的流行病学调查

目的 调查我国城市地区20～69岁成人牙本质敏感的患病状况及其影响因素,以期为临床提供资料.方法 调查对象为北京、上海、广州、武汉、成都、西安共6个城市20～69岁居民,采用多阶段、分层、等容鼍随机抽样的方法,样本来自6个城市的36个抽样点.调查内容包括牙本质敏感的临床检查和问卷调查.牙本质敏感的诊断结合了受检者的自我感觉和临床上冷空气喷吹敏感检查.临床检查是在常温下,距离牙面1 cm处气枪吹压缩空气,受检者确认是否敏感或疼痛.结果 7939名20～69岁成人完成了牙本质敏感的临床检查和问卷调查.在调查人群中,40.7%(3230/7939)的受检者自述有牙本质敏感的症状,结合气枪吹气诊断并排除龋齿等其他引起疼痛的疾病,受检人群牙本质敏感的患病率为29.7%(2354/7939),人均牙本质敏感牙数为1.4颗.50～59岁年龄组人群牙本质敏感的患病率最高,为39.1%(622/1592).牙本质敏感好发于前磨牙,最常见的引起牙本质敏感的刺激因素为冷刺激.女性、受教育程度低、有牙龈退缩、附着丧失及胃食管反流史等因素与牙本质敏感的发生有关.结论 我国城市地区20～69岁成人牙本质敏感很常见,应得到口腔专业人员的关注.

A national survey on dentin hypersensitivity in Chinese urban adults

Objective To investigate the prevalence of dentin hypersensitivity in Chinese urban adults aged between 20-69 years old and the factors related to dentin hypersensitivity.Methods The Chinese national survey on dentin hypersensitivity was conducted in 20-69 years old adults in six representative cities,Beijing,Shahghai,Guangzhou,Wuhan,Chengdu,and Xi'an in 2008.A muhi-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 resportse to a blast of cold air from a triple syringe administered to a tooth surface in 1 cm. Results 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. When confirmed using a blast of air from a triple syringe and by ruling out other causes of sensitivity,such as caries,the prevalence was 29.7% (2354/7939),and the mean number of sensitive teeth was 1.4.The highest prevalence of dentin hypersensitivity39.1%(622/1592)]was found in 50-59 years old group.The commonest teeth affected were the premolar teeth and the commonest initiating factor was cold drinks.Female,low education level,with gingival recession,attachment loss,and with the history of acidic substances derived from the stomach was related to dentin hypersensitivity.Conclusions Dentin hypersensitivity was comnlon in 20-69 years old Chinese urban adults.Dental professionals should give further emphasis to it.
