The purpose of this study was to evaluate three-year incidence of and risk factors for tooth loss in community-dwelling adults. Subjects were 269 (male 128,female 141) dentate adults in a town of Niigata Prefecture who visited both oral examination that were carried out in 1997 (baseline examination) and 2000 (follow-up examination). The follow-up rate was 37.2%. The average age at baseline was 60.6 (SD=12.8). We used multiple-logistic regression model to quantify tooth-specific and person-level risk factors for tooth loss by using variables of oral examination and questionnaire at baseline.Three-year incidence of tooth loss was 4.9% in tooth-level, 48% in person-level. The average number of missing teeth per year was 0.33.The results of person-level multiple logistic regression analysis showed that tooth loss was more common in persons with 10-27 present teeth, decayed teeth, oral symptom, history of dental visit within a year and habit not using interdental brush or dental floss. By using tooth-level multiple logistic regression analysis showed that incidence of tooth loss is higher in wisdom tooth, decayed tooth, crowned tooth, abutment tooth of bridge and tooth with mobility.

这项研究的目的是评估社区成年人三年内牙齿脱落的发生率和危险因素。研究对象为新泻县某镇269名(男128名，女141名)齿状齿成年人，分别于1997年(基线检查)和2000年(随访检查)进行口腔检查。随访率为37.2%。基线平均年龄为60.6岁(SD=12.8)。采用多因素Logistic回归模型，以口腔检查和问卷调查为变量，以基线为基准线，将牙齿缺失的危险因素量化，三年的牙齿缺失发生率分别为4.9%和48%。多因素Logistic回归分析显示，10~27颗现牙、龋齿、口腔症状、一年内就诊史、习惯不使用牙间刷牙或牙线的人群以缺牙多见。牙齿水平的多元Logistic回归分析显示，智齿、龋齿、冠牙、桥基牙、活动性牙的脱牙发生率较高。
