To identify the times of emergence of the permanent teeth of Canadian Eskimos (Inuit), 368 children and adolescents were examined. The presence or absence of all permanent teeth except the third molars was recorded and these data subjected to probit analysis. Female emergence times were advanced over males. Generally, the Inuit of both sexes showed statistically significant earlier emergence times than Montreal children, except for the incisors. The present results do not support hypotheses indicating that premature extraction of the deciduous teeth advances the emergence of their succedaneous counterparts. There is some indication the controls of deciduous tooth emergence continue to play some part in emergence of the permanent dentition, especially the first permanent teeth that emerge.
为了确定加拿大爱斯基摩人（因纽特人）恒牙萌出的时间，对368名儿童和青少年进行了检查。记录了除第三磨牙外所有恒牙的萌出情况，并对这些数据进行了概率分析。女性的萌出时间比男性早。一般来说，除了门牙外，因纽特男女的萌出时间在统计学上都显著早于蒙特利尔的儿童。目前的结果不支持乳牙过早拔除会使相应恒牙萌出提前的假说。有迹象表明，乳牙萌出的控制因素在恒牙列萌出过程中，尤其是最早萌出的恒牙萌出过程中，仍发挥着一定作用。
