The accuracy for predicting mesiodistal widths of unerupted permanent canines and premolars from x-rays and their estimations based on the already erupted permanent teeth were tested in a group of Israeli children. The observed posteruptive widths related more closely to predicted values obtained from x-ray measurements than from tabulated estimations.
在一组以色列儿童中，测试了通过X射线预测未萌出恒牙尖牙和前磨牙近远中宽度的准确性，以及基于已萌出恒牙的估计值。观察到的萌出后宽度与通过X射线测量获得的预测值的相关性，比与表格估计值的相关性更高。
