福建省中老年人群牙周附着丧失的抽样调查

目的应用牙周附着丧失（AL）为指标,了解福建省中老年人群牙周破坏状况,为开展中老年人牙周预防保健提供基线资料。方法采用多阶段、分层、等容量、不等比、随机抽样的方法,抽取福建省6个区（县）36个调查点的720名中年人（35~44岁）和720名老年人（65~74岁）,男女各半,对他们的牙周AL情况以及严重程度进行抽样调查,同时比较Ⅰ、Ⅲ象限和Ⅱ、Ⅳ象限的牙周AL差异。结果中年组中,女性AL 0~3 mm的检出率和检出牙数的均数都高于男性（P〈0.01和P〈0.05）,AL？6 mm的检出率和检出牙数的均数都低于男性（P〈0.01和P〈0.01）;男性AL 4~5 mm的牙数的均数高于女性（P〈0.01）;女性的检出率略高于男性,但差别无统计学意义（P〉0.05）。老年组中,女性AL 0~3 mm和4~5 mm的检出率均高于男性（P〈0.05和P〈0.05）,AL≥6 mm的检出率低于男性（P〈0.01）,AL 4~5 mm和≥6 mm的牙数的均数低于男性（P〈0.01和P〈0.01）;男性和女性AL 0~3 mm的牙数均数差别无统计学意义（P〉0.05）。各组别Ⅰ、Ⅲ象限和Ⅱ、Ⅳ象限的牙周AL检出率差别无统计学意义（P〉0.05）。结论老年人群的牙周AL较中年人严重。男性的牙周AL较女性的牙周AL严重。交叉象限的半口牙周AL基本上可以反映全口牙周AL的情况。

Sample Survey on Periodontal Attachment Loss of Middle-aged and Old People in Fujian Province

Objective To study periodontal conditions of middle-and elded-aged in fujian province,and provide fundamental guidance for oral health care of these people.Method Using the method of multistage,stratified,equal capacity,disproportion,and simple random sampling,the periodontal attachment loss,periodontal severity and the AL comparison between Ⅰ,Ⅲ quadrant and Ⅱ,Ⅳ quadrant were assessed among 720 middle-aged（33～44 years old） and 720 elded-aged（65～74 years old）,with a gender ratio of half to half,from 36 investigating areas of 6 counties in Fujian Province.Results In middle-aged group,the prevalence and mean number of teeth with AL among 0～3 mm were higher in females（P0.01P0.05）,and the prevalence and mean number of teeth with AL≥ 6 mm were higher in males（P0.01P0.01）.While the mean number of teeth with AL among 4～5 mm was higher in middle-aged males（P0.01）,and the prevalence of teeth with AL among 4～5 mm was lower in middle-aged females,there was no statistically significant difference between middle-aged males and females（P0.05）.In elded-aged group,the prevalence of teeth with AL among 0～3 mm and 4～5 mm was higher in females（P0.05 P0.05）,while the prevalence of teeth with AL≥ 6 mm was higher in males（P0.01）.The mean number of teeth with attachment loss among 4～5 mm and ≥6 mm was lower in old females（P0.01P0.01）.The comparison of mean number of teeth with AL among 0～3 mm between old females and males was no statistically significant difference（P0.05）.The comparison of AL betweenⅠⅢ quadrant and Ⅱ Ⅳ quadrant was also of no statistically significant difference（P0.05）.Conclusion The AL of elded-aged was more severe than that of middle-aged.In male,the AL was worse.The AL in cross-quadrant of split-mouth could represent the periodontal condition.
