| Outline of Final Research Achievements |
We investigated what extent the individual variation was in mandibular bone quantity and a major bone matrix, collagen, and thier relation to tooth longevity. At the manidibular first molar region, cortical bone showed thicker in men than in women. Men did not exhibit the thickness decrease by age, while women did. Trabecular bone density did not differ by sex and age. A large extent of individual difference exists in the quantities of cortical and trabecular bones. In the mandibular mental region, the bone collagen content showed a large extent among individuals, though the extent of lysine hydroxylation of collagen did a relatively small variarion. The subjects showing larger content of collagen had almost two times as number of the remaining teeth as those showing smaller content of collagen. It is suggested that the mandibles have a large variation of collagen content among individuals and the variation could be a factor for tooth longevity.
