Abstract : In our clinic we’ve investigated the relation in which we’ve had interest between a habit of life include a dietary life and health. When we visited the Republic of Kenya on February 2000, we went into the village of the Masai tribe and examined their oral cavity, a posture of the whole body, a countenance and a dietary life and so on. We report we learned original statue of human being from them through their state of teeth and gingiva and arch of teeth. And we consider the problem of physical degeneration which has now rapidly increased in Japanese by comparing with them under this investigation.
