The aim of this study was to examine risk factors for tooth loss and edentulism in institutionalised elderly people.
Six-year prospective cohort study.
Twenty nine of the 30 institutions for elderly people in Kitakyushu, Japan.
Four hundred and eighteen of the 1,096 subjects who were dentate at the baseline examination.
Factors that influenced tooth loss and edentulism.
In both sexes, older subjects had fewer remaining teeth at baseline. Males lost more teeth than females, and edentulism was also more likely in males than in females. Stepwise multiple linear regression analysis showed that the number of teeth, number of decayed teeth, periodontal pocket depth, and plaque index were significant predictors for the number of teeth lost. The incidence of edentulism was higher in males than in females. Stepwise multiple logistic regression analysis revealed that poorer mental health status, fewer teeth, having deep periodontal pocket, and poorer oral hygiene status were independently associated with the six-year incidence of edentulism.
Tooth loss in institutionalised elderly people in Japan is related to both poor oral health status and poor mental health status.
本研究旨在调查机构养老老年人牙齿缺失和无牙症的危险因素。
六年前瞻性队列研究。
日本北九州市30家老年人机构中的29家。
在基线检查时有牙的1096名受试者中的418名。
影响牙齿缺失和无牙症的因素。
在两性中，年龄较大的受试者在基线时剩余牙齿较少。男性比女性掉牙更多，男性患无牙症的可能性也高于女性。逐步多元线性回归分析表明，牙齿数量、龋齿数量、牙周袋深度和菌斑指数是牙齿缺失数量的重要预测因素。男性无牙症的发生率高于女性。逐步多元逻辑回归分析显示，心理健康状况较差、牙齿较少、牙周袋较深和口腔卫生状况较差与无牙症的六年发病率独立相关。
日本机构养老老年人的牙齿缺失与口腔健康状况差和心理健康状况差均有关。
