To describe the prevalence of non-carious cervical lesions (NCCLs) and to assess the relative affects of risk factors on NCCLs in middle-aged and elderly people in Hubei Province, China.
A sample of 2,160 adults, aged 35-44 years and 65-74 years and balanced by age, gender, and urbanization, participated in the cross sectional epidemiological survey. Non-carious cervical lesions were examined using a modified Tooth Wear Index. Data were collected based on structured questionnaires that assessed general information as well as oral health.
The prevalence of non-carious cervical lesions was 38.8% for 35-44-year-olds and 56.6% for 65-74-year-olds. The first premolars, canines, and second premolars showed the highest prevalence of lesions, while the second molars demonstrated the least. Several risk factors such as age (OR = 2.45, p < 0.001), location (OR = 1.68, p = 0.001), frequency of toothbrushing (OR = 1.33, p = 0.016), bruxism (OR = 1.37, p < 0.001), and family income (OR = 1.44, p < 0.001) were found to be associated with lesion occurrence.
The prevalence of non-carious cervical lesions was relatively high in the middle-aged and elderly persons in China and was also associated with socio-behavioural risk factors.
描述非龋性颈部病变（NCCLs）的患病率，并评估危险因素对中国湖北省中老年人NCCLs的相对影响。
选取2160名年龄在35 - 44岁和65 - 74岁之间、按年龄、性别和城市化程度均衡的成年人参与横断面流行病学调查。使用改良的牙齿磨损指数检查非龋性颈部病变。基于结构化问卷收集数据，该问卷评估了一般信息以及口腔健康状况。
35 - 44岁人群中非龋性颈部病变的患病率为38.8%，65 - 74岁人群中为56.6%。第一前磨牙、犬齿和第二前磨牙的病变患病率最高，而第二磨牙的患病率最低。发现年龄（OR = 2.45，p < 0.001）、部位（OR = 1.68，p = 0.001）、刷牙频率（OR = 1.33，p = 0.016）、磨牙症（OR = 1.37，p < 0.001）和家庭收入（OR = 1.44，p < 0.001）等几个危险因素与病变发生有关。
中国中老年人中非龋性颈部病变的患病率相对较高，且与社会行为危险因素有关。
