Mesiodistal and buccolingual crown diameters were measured from dental casts representing the deciduous dentitions of 197 Aboriginal children from the Northern Territory of Australia. Double determination analysis indicated that the semi-automatic recording procedure used was reliable leading to observer errors of no practical significance. Tooth-size was greater in the male subjects but the sexual dimorphism was less marked than in the permanent teeth of the same subjects. The mandibular teeth were more uniform than maxillary with respect to buccolingual size relative to mesiodistal. Extremes of general tooth-size were more marked in the deciduous dentition than in the permanent as a consequence of the relatively large deciduous second molar which in Aboriginals approximates in size the permanent first molar of many other ethnic groups.
从代表澳大利亚北领地197名原住民儿童乳牙列的石膏模型上测量了近远中径和颊舌径。双测定分析表明，所采用的半自动记录程序是可靠的，导致的观察者误差不具有实际意义。男性受试者的牙齿尺寸更大，但与同一受试者的恒牙相比，性别二态性不那么明显。就颊舌径相对于近远中径而言，下颌牙比上颌牙更均匀。由于乳牙第二磨牙相对较大，在原住民中其大小接近许多其他种族的恒牙第一磨牙，因此乳牙列中牙齿总体尺寸的极端情况比恒牙列中更明显。
