Abstract

Objectives: to test the hypothesis of sex-dependent differences among individuals using the Wits appraisal. Methods: a descriptive cross-sectional study was conducted with 135 lateral cephalometric radiographs of patients over 18 years old (78 women and 57 men), classified as skeletal class I according to the ANB angle. The Wits appraisal values were measured and compared between sexes using the Mann-Whitney test to evaluate the hypothesis guiding this work. Results: the median value of the Wits appraisal was-1.77 mm. in women and-1.16 mm. in men. No statistically significant differences were found between sexes (p = 0.5597). Conclusions: it is suggested that in orthodontic practice, no adjustment of the norm between sexes be made when establishing the skeletal class diagnosis
