摘要
笔者对400个离体上颌前磨牙进行了牙体测量,应用统计学方法对各测量值作了多因素分析,根据最小二乘法建立了上颌前磨牙全长和根长的预报方程且验证了其可靠性,为临床预测根长、全长提供了预报手段。
400 maxillary premolars were measured in the length of the full tooth, crown and root, the width of the crown and tooth neck and the depth of the crown and tooth neck. The measuring values were statistically analysed with multifactor analysis, using the vector comparision of the mean and the principle component analysis. The forecasting equations of the full length and root length of maxillary premolars were established. The clinical significance of the results was discussed.
