The aim of this study is to investigate whether there is a significant sex difference or not in the mesiodistal tooth width between Saudi males and females. 720 teeth were measured from a pre-treatment orthodontic study casts with equal distribution of the two sexes. The subjects were aged 13 to 20 years. An electronic digital caliper was used for the measurements. For the statistical analysis the Student's t-test was used. The result of this investigation showed that the canines in both jaws exhibited a significant sex differences while the other teeth did not. Hence, this study confirms results obtained by other investigators and emphasize the fact that mesiodistal tooth width is an important factor in the assessment of crowding, spacing and orthodontic treatment planning.
本研究的目的是调查沙特男性和女性之间近远中牙宽度是否存在显著的性别差异。从一项正畸治疗前研究模型中测量了720颗牙齿，两性分布均等。受试者年龄在13至20岁之间。使用电子数字卡尺进行测量。统计分析采用学生t检验。本调查结果显示，上下颌的尖牙均表现出显著的性别差异，而其他牙齿则没有。因此，本研究证实了其他研究者获得的结果，并强调了近远中牙宽度是评估牙列拥挤、间隙和正畸治疗计划的一个重要因素。
