To assess the correlation between Wits and AF-BF appraisals with the ANB angle, and verify the influence of the facial type on these appraisals.
Lateral cephalometric radiographs from 118 untreated individuals were separated into 3 groups according to the facial pattern (brachyfacial, mesofacial, and dolichofacial). The radiographs were digitized and submitted to ANB angle and Wits and AF-BF appraisals on computer software. All radiographs were retraced for intraobserver and interobserver error tests.
The Student's t test demonstrated no statistically significant differences on the intraobserver's test (P > .05). There were statistically significant differences in the readings of Wits values of the 3 groups and for AF-BF values in the brachyfacial and mesofacial groups (P <.05). The multiple linear regression tests demonstrated high correlation between ANB and AF-BF for the 3 groups (r2, 0.768). The same result was found for ANB and Wits (r2, 0.624).
Facial pattern does not have an influence on the correlation between ANB and AF-BF nor between ANB and Wits, but it does influence the measurements of ANB, AF-BF, and Wits.
评估Wits值和AF - BF值与ANB角之间的相关性，并验证面部类型对这些评估的影响。
将118例未经治疗个体的头颅侧位X线片根据面部形态（短面型、中面型和长面型）分为3组。将X线片数字化，并在计算机软件上进行ANB角、Wits值和AF - BF值评估。所有X线片均重新测量以进行观察者内和观察者间误差测试。
Student's t检验显示观察者内测试无统计学显著差异（P >.05）。3组的Wits值读数以及短面型和中面型组的AF - BF值读数存在统计学显著差异（P <.05）。多元线性回归测试表明3组中ANB与AF - BF之间具有高度相关性（r2，0.768）。ANB与Wits之间也得到相同结果（r2，0.624）。
面部形态对ANB与AF - BF之间以及ANB与Wits之间的相关性没有影响，但对面部形态对ANB、AF - BF和Wits测量值有影响。
