从中央窝到恒牙上磨牙牙冠周边的距离测量上的标准化咬合照片的牙模代表210名男性和181名女性的原住民从Yuendumu在澳大利亚北领地。在男性和女性的第一磨牙是最大的牙齿，但它显示出最小的变化。在颊舌方向构建的桡骨的距离的变异性往往大于横向近远中桡骨。从第一磨牙到第三磨牙系列中最明显的尺寸减小与牙冠的远舌侧部分有关，这也是变化最大的区域。磨牙近中轮廓半径的大小差异不明显。性别二型性在大多数牙冠半径中是明显的，在第二磨牙中最为明显。
Distances from the central pit to the perimeter of the crown of permanent upper molars were measured on standardized occlusal photographs of dental casts representing 210 male and 181 female Aboriginals from Yuendumu in the Northern Territory of Australia. In both males and females the first molar was the largest tooth but it showed least variability. Variabilities of the distances tended to be greater for radii constructed in the buccolingual direction than for the transverse mesiodistal radii. The most marked size reduction in the molar series from first to third related to the distolingual part of the crown, which was also the most variable region. Size differences between molars in the mesial contour radii were not marked. Sexual dimorphism was evident in most crown radii, being most marked for the second molar.
