Diachronic Changes Of Tooth Wear In The Deciduous Dentition Of The Japanese

Occlusal attrition in deciduous dentition was examined in the Japanese subadult skeletal samples of the Neolithic Jomon (ca. 12000-300 BC), immigrant Yayoi (ca. 300 BC-300 AD), and medieval Kamakura (1300-1600 AD) periods, compared to modern Japanese children. The dentitions of all skeletal samples showed relatively heavier attrition than in modern children. The attrition of Jomon children was not heavier than other skeletal samples.
