宁夏地区2 628名成年人牙周健康状况的研究

目的了解宁夏地区回族和汉族成年人的牙周健康状况,为该地区开展口腔健康预防保健工作提供理论依据。方法采用世界卫生组织口腔健康调查方法及第三次全国口腔健康流行病学调查方案,对宁夏地区2 628名成年人的牙周健康状况进行检查,检查项目包括牙龈出血（即探诊后出血,BOP）、牙石、探诊深度（PD）及附着丧失（AL）情况。应用SPSS 15.0软件对数据进行统计分析。结果1）BOP位点阳性率、牙石检出率、PD在36～45岁、46～59岁组达到高峰但在大于等于60岁组反而降低;牙周炎患病率、AL≥4 mm位点百分比随着年龄的增长而逐渐增加。2）除AL≥4 mm位点百分比外,其他各项指标在性别之间均无统计学差异。3）山区人群的BOP位点阳性率、牙石检出率、PD、牙周炎患病率及AL≥4 mm位点百分比均高于川区。4）回族人群的BOP位点阳性率、牙石检出率、PD、牙周炎患病率及AL≥4 mm位点百分比均低于汉族。结论宁夏地区成年人牙周健康状况受年龄、性别、民族和地区的影响。

Study on the periodontal health status of 2 628 adults in Ningxia Hui autonomous region

Objective To study the periodontal health status of Hui and Han adults in Ningxia Hui autonomous region, thus to provide scientific basis for the establishment of oral health care policies in this region. Methods 2 628 adults in Ningxia Hui autonomous region were investigated in this study according to the criterion issued by World Health Organization on the basic methods of oral health investigation and China oral health third epidemiological survey protocol. The inspection item included gingival bleeding（bleeding on probing, BOP）, dental calculus, probing depth（PD） and attachment loss（AL）. SPSS 15.0 statistical software was applied to analyze the results. Results 1）The positive rate of BOP sites, detection rate of calculus and PD were peaked in 36-45 and 46-59 years old, but in the ≥60 age group rather lower. The prevalence of periodontitis and the percentage of AL≥4 mm sites were increased with the adults’age. 2）In addition to the percentage of AL≥4 mm sites, the differences of the other indicators between the genders were not statistically significant. 3）The positive rate of BOP sites, detection rate of calculus, PD, the prevalence of periodontitis and the percentage of AL≥4 mm sites were higher for the mountain areas than the plain areas. 4）Hui population’s positive rate of BOP sites, detection rate of calculus, PD, the prevalence of periodontitis and the percentage of AL≥ 4mm sites were significantly lower than the Han population in Ningxia. Conclusion The periodontal health status of adults in Ningxia Hui autonomous region is associated with age, gender, nationality and region.
