Crown Dimensions of the Maxillary Molars in Tupaia glis

抄録

The crown dimensions of the maxillary molars in Tupaia glis were measured, and the most common molar size sequence was M¹>M^2>M³. The M² and M³ molars were smaller than the M¹ in the mesiodistal crown diameters. With regard to the buccolingual diameters, the distal part of M¹ and mesial part of M² were relatively larger and less variable in size. This stable area corresponded to the inflection point of the maxillary arch curve. These results could be explained from a functional morphological standpoint.
