目的：了解陕西省某贫困县农村居民口腔健康状况及人们对口腔保健知识的知晓程度，调查当地农村居民龋病、牙周病的发病情况，并以此为依据指导该地区农村居民的口腔预防保健工作。方法：根据《第四次全国口腔健康流行病学调查报告》的调查方法，采用抽样调查的方式进行，调查对象分为35~44岁、45~54岁、55~64岁和65~74岁4个年龄段，按性别分组，总样本量为1258人，调查内容分为口腔健康状况调查和口腔健康问卷调查，龋病以患龋率和龋均数，牙周病以牙龈出血、牙结石和牙周袋的检出率作为统计指标。结果：总患龋率为92.2%，受检者龋均为7.87颗，牙龈出血检出率为88.8%，牙结石检出率为96.5%，全口无牙率为2.5%，义齿修复率为29.8%。结论：患龋率、牙龈出血和牙石检出率和全口无牙率均高于第四次全国口腔健康流行病学抽样调查结果，失牙率高、义齿修复率也较高，应加强农村居民口腔健康防治工作，改善农村居民口腔医疗条件。
Purpose: To understand the oral
health status of rural residents in X County, Shaanxi Province and their
knowledge of oral health care, and to investigate the incidence of dental
caries and periodontal disease among rural residents in X County, Shaanxi

health questionnaire survey. The detection rate of gingival bleeding, dental
calculus and periodontal pocket was used as statistical index of periodontal
disease. Result: The total incidence rate of dental caries was 92.2%, the
number of caries examined was 7.87, the detection rate of gingival bleeding was
88.8%, the detection rate of dental calculi was 96.5%, the edentulous rate was
2.5%, and the restoration rate of denture was 29.8%. Conclusion: The incidence
of dental caries, gingival bleeding, the detection rate of dental calculus and
the total edentulous rate were higher than those of the fourth National Oral
Health Epidemiological sampling Survey, the tooth loss rate was high and the
restoration rate of denture was also high. The prevention and treatment of oral
health of rural residents should be strengthened, improving the oral medical
conditions of rural residents.
