RESULTS: The following results were obtained: 1. 53.6% of all subjects believe that they are healthy. The average values of height, weight, BMI, body fat, lean body fat and total water were 148.8+/-11.2cm, 46.9+/-10.5kg, 21.2+/-3.5kg/m2, 26.7+/-6.9%, 73.0+/-7.1%, and 53.4+/-5.2%, respectively. 2. The average number of teeth remaining in the subjects were 3.50+/-571: the number of maxillary teeth remaining were 1.08+/-2.88; and the number of mandibular teeth remaining were 2.41+/-3.76. The maximum number of teeth remaining among subjects were 22 teeth, and the fully edentulous(no natural teeth) people were 76.3%. The oral conditions of the subjects were 52.6% using denture, 23.7% using natural teeth and 23.7% masticating edentulous ridge without denture. 3. In terms of oral condition in self-assessment of health, digestive ability, and chewing ability : On self-assessment of health, 47.1% of those wearing denture group responded as feeling food, 56.5% of those of edentulous without denture, and 65.2% in group of matural teeth only. On self-assessment of digestive ability, 82.4% of those in group of denture responded as feeling food, 65.2% of those in group of no teeth and no denture, and 73.9% of those in group of natural teeth only.
