The purpose of this study was to investigate differences in oral condition and health status between persons with 20 or more teeth at the age of 80 (8020 elderly) and persons of the same age with less than 20 teeth (non-8020 elderly). This study was conducted by a team belonging to the Aichi Dental Association. Number of remaining teeth, Community Periodontal Index of Treatment Needs (CPITN), salivary blood test, masticatory ability, bone mineral density (BMD), grip strength, balance test (length of time one can stand on one leg with eyes open), height, weight and body mass index (BMI) were all examined. The percentages of CPITN code 0, 1 and 2 were 68% in the 8020 male elderly and 72% in the 8020 female elderly. The positive percentage in the salivary blood test in the 8020 elderly was lower than that in the non-8020 elderly. Masticatory ability was 1.55g in the 8020 male elderly, and 1.53 g in the 8020 female elderly. Relative masticatory ability in the 8020 female elderly was 20% higher than that in the non-8020 female elderly. BMD in the 8020 female elderly was significantly higher than that in the non-8020 female elderly. Grip strength in the 8020 elderly was also significantly higher than that in the non-8020 elderly. The duration of balance test in the 8020 male elderly was 2.2 times longer than that in the non-8020 male elderly. The 8020 elderly showed good oral condition and health status was found to be better in the 8020 elderly than in the non-8020 elderly.
