The Wits values for various ethnic groups are different and the applicability of the norms described in these analyses to different populations is difficult. The objectives of this study were to establish the normal values of Wits appraisal in a sample from the western region of Saudi Arabia and to evaluate the existence of gender dimorphism. Also, to compare the results with previously published Wits values.
A total of 66 lateral cephalometric digital radiographs of Saudi patients from the western region (25 males and 41 females, mean age 19.32±8.16 years and 20.88±8.77 years, respectively). All subjects had angle class-I occlusion, well-balanced faces, all premolars had erupted and in occlusion, and no history of orthodontic treatment. Tracing was performed using the VistadentOC(®) software.
Wits mean values were greater in males (-0.73±2.48) than females (1.79±2.06), with significant gender difference (P<0.001). Comparisons with previously published showed that there is a significant differences between ethnic groups, especially in females' data.
Wits appraisal appears to be gender-specific and ethnicity-specific for female values.
不同种族群体的Wits值不同，这些分析中所描述的标准对不同人群的适用性存在困难。本研究的目的是确定沙特阿拉伯西部地区一个样本中Wits评估的正常值，并评估性别二态性的存在。此外，将结果与先前发表的Wits值进行比较。
共收集了来自沙特西部地区患者的66张头颅侧位数字化X线片（男性25例，女性41例，平均年龄分别为19.32±8.16岁和20.88±8.77岁）。所有受试者均为安氏I类咬合关系、面部匀称、所有前磨牙均已萌出并咬合，且无正畸治疗史。使用VistadentOC(®)软件进行描图。
男性的Wits平均值（-0.73±2.48）高于女性（1.79±2.06），性别差异有统计学意义（P<0.001）。与先前发表的数据比较显示，不同种族群体之间存在显著差异，尤其是女性数据。
Wits评估对于女性值似乎具有性别特异性和种族特异性。
