| Outline of Final Research Achievements |
The morphological changes in the primary dentition of various human populations have studied in terms of the dietary habits in childhood. The progression of attrition of the deciduous teeth was not necessarily as advanced as in populations of older period. However, a strong progression of attrition was observed in the anterior teeth of Jomon people, and the characteristic food intakes of hunter-gatherer in childhood was suggsested. In modern Mongolian children, it was suggested that the use of deciduous molars is advanced more pronounced than in modern Japanese. It is generally said that the food intake in Mongolian children depends on meat, and it is assumed that the fact is reflected by the difference of characteristic attrition pattern of deciduous dentition between Mongolian and Japanese children.
