To investigate oral health status in the residents of Sichuan Province, southwest China, a cross-sectional study was performed using the latest Oral Health Survey Basic Methods recommended by the World Health Organization. A multistage stratified random cluster-sampling method was used to enroll participants from the following three groups: children aged 3-5 years, adolescents aged 12 years, and people aged 65-74 years. In these three groups, the mean numbers of teeth that were affected by caries were 3.28, 0.86 and 5.13, respectively, resulting in a prevalence of 63.47%, 37.20% and 83.20%, respectively. Relative to the high rate of decayed teeth, the prevalence of fillings was very low in all age groups (0.97%, 7.24% and 5.43%, respectively). In the 12-year-old adolescent group, only 3.61% had good pit and fissure sealing. In addition, the rate of dental fluorosis was 24.80%, and the Community Fluorosis Index value was 0.39. In the elder group, the community periodontal index was 2.92. The prevalence in the elderly of having lost at least one tooth was 75.54%. Additionally, 4.44% of these participants were edentulous. The incidence of dental prosthesis was 51.75%, the proportion with a removable partial denture, a fixed denture, full dentures, dental implants and an informal fixed bridge was 21.59%, 11.45%, 4.64%, 0 and 16.67%, respectively. In this study, 8.2% of the elderly participants were affected by different types of oral mucosal lesions. Among such lesions, recurrent aphthous ulcers were most prevalent (2.69%) and oral lichen planuses were second (1.6%). The conclusion presented in this survey is that oral diseases, especially dental caries and periodontal disease, are frequent and common in Sichuan province, China. Moreover, the treatment rate is very low, and primary prevention and treatment options are therefore urgently needed in this population.
为了调查中国西南部四川省居民的口腔健康状况，采用世界卫生组织最新推荐的《口腔健康调查基本方法》进行了一项横断面研究。采用多阶段分层随机聚类抽样方法，从以下三组人群中招募参与者：3-5 岁儿童、12 岁青少年和 65-74 岁人群。这三组人群中，患龋的平均牙齿数分别为 3.28、0.86 和 5.13，相应的患龋率分别为 63.47%、37.20%和 83.20%。相对于高龋齿率，所有年龄组的补牙率都非常低（分别为 0.97%、7.24%和 5.43%）。在 12 岁的青少年组中，仅有 3.61%的人进行了良好的窝沟封闭。此外，氟斑牙的发生率为 24.80%，社区氟斑牙指数值为 0.39。在老年组中，社区牙周指数为 2.92。至少有一颗牙缺失的老年人患病率为 75.54%。此外，4.44%的参与者无牙。牙修复体的发生率为 51.75%，可摘局部义齿、固定义齿、全口义齿、种植牙和非正式固定桥的比例分别为 21.59%、11.45%、4.64%、0 和 16.67%。在这项研究中，8.2%的老年参与者受到不同类型的口腔黏膜病变的影响。在这些病变中，复发性阿弗他溃疡最为常见（2.69%），口腔扁平苔藓次之（1.6%）。本调查得出的结论是，口腔疾病，尤其是龋齿和牙周病，在中国四川省较为常见和普遍。而且，治疗率非常低，因此该人群急需进行初级预防和治疗。
