| Outline of Final Research Achievements |
In this study, changes in defect sites and patterns were examined using longitudinal data obtained from a large number of community-dwelling elderly. As the results, interval of regular maintenance, occlusal supports, molar, periodontal pocket depth, caries, restoration / prosthetic condition, missing adjacent teeth, presence of opposite teeth, and use of dentures showed significant associations with tooth loss. Additionally, it was shown that those who had no occlusal support of the molars were at high risk of loss of the anterior teeth after 6 years.

| Academic Significance and Societal Importance of the Research Achievements |
大規模疫学調査による分析結果より，歯の欠損の拡大に対して，臼歯部の咬合支持が強く関連していることが示された．このことは，予防歯学を実施する上で重要な示唆を与えるものと考えられる．
