粤西北连南瑶族成人牙周病流行病学调查

目的：调查粤西北连南瑶族成人牙周病流行情况，为开展瑶族人牙周病防治措施提供依据。方法：采用多阶段分层等容量随机抽样方法，抽取连南县城和各乡镇的720名瑶族成人，进行牙周病流行病学调查。结果：连南瑶族成人牙周病检出率91．81％，晚期牙周病检出率50．84％，牙周病检出率随着年龄的增长而增高，且乡镇明显高于县城（χ2＝28．08，P＜0．01），男性明显高于女性（χ2＝8．15，P＜0．01）。牙石检出率乡镇明显高于县城（χ2＝19．89，P＜0．01），男性明显高于女性（χ2＝8．17，P＜0．01）。牙龈出血检出率乡镇明显高于县城（χ2＝11．39，P＜0．01），男性明显低于女性（χ2＝85．77，P＜0．01）。结论：连南瑶族成人牙周病的流行情况较严重，且城乡、男女性别差异明显，预防工作应以乡镇和男性瑶族人为重点，进行口腔卫生宣教和戒烟宣传，加强对牙周病系统治疗、洁牙和及时镶牙的宣传，提高瑶族人牙周病就诊率和治疗率，从而降低牙周病患病率。

The epidemiological and intervention of periodontal disease prevalence among adults in Yao of Liannan in Northwest of Guangdong

Objective:To provide basis for carrying out the effective and specific prevention of periodontal disease in Yao of Liannan by investigating the periodontal disease of individuals in Yao of Liannan in Northwest of Guangdong. Method:720 Yao individuals were living in Liannan County and township whom were selected by multistage stratified ran-dom sampling. And then,the epidemiology of priodontosis investigation was made to them. Result:The periodontal disease detection rate of Yao individuals of Liannan was 91.81 %. And the detection rate of advanced periodontal disease was 50.84%. The basis shown that the detection rate of periodontal disease increased with age,which the people living in township were higher than in county (χ2=28.08,P<0.01),and male was higher than female (χ2=8.15,P<0.01). The Plaque detection rate shown that the people living in township were higher than in county (χ2=19.89,P<0.01),and male was higher than fe-male(χ2=8.17,P<0.01). The detection rate of gingival bleeding shown that the people living in township were higher than in county (χ2=11.39,P <0.01),and male was higher than female (χ2=85.77,P <0.01). Conclusion:The periodontal disease prevalence among adults in Yao of Liannan was more serious.
