| Research Abstract |
The purpose of this study was to quantify the difficulty of prosthodontic treatments. A total of 461 independent community-dwelling people older than 55years in Ohasama, a Japanese rural area, participated in this study. Subjects were divided into four categories area A-D by the patterns of remaining teeth according to the Dento-occlusal triangula. To evaluate oral health-related Quality of life (OHRQOL), the Oral Impacts on Daily Performances(OIDP) scale was administered. Multivariate logistic regression analysis were applied to investigate correlations between the four categories and OHRQOL and to calculate the odds ratio(OR), adjusted for age, gender, chronic disease, smoking and drinking habits, depressive tendency, cognitive function and utilization of dental services over the past one year. Because it was thought that OHRQOL decline group is the group which is hard to be provided of the prosthetic curative effect, the calculated odds ratio is related to degree of difficulty of prosthodontic treatments. It was suggested that this method was applicable to the quantification of the degree of difficulty of the prosthetic treatments.
