The objective of the present study was to investigate whether there was a significant difference or not in mesiodistal tooth width between the right and left sides in a Saudi sample. The measurements were obtained from 720 teeth of pretreatment orthodontic study casts. The results showed no significant statistical difference between right and left sides, which in agreement with literature. Thus, measurement of one side could be regarded as truly representative when the corresponding measurement on the other side was unobtainable.
本研究的目的是调查沙特样本中左右两侧牙齿近远中宽度是否存在显著差异。测量数据来自正畸治疗前研究模型的720颗牙齿。结果显示左右两侧之间无显著统计学差异，这与文献一致。因此，当无法获得另一侧的相应测量值时，一侧的测量值可被视为具有真正的代表性。
