Sagittal (Class I, II or III) and vertical skeletal pattern (average, increased or decreased Frankfort\u2010Mandibular Plane Angle (FMPA)) were recorded. Samples were categorized into four groups according to OJ severity: OJ\u2003\u2264\u20033.5\u2003mm, 3.5\u2003mm\u2003&lt;\u2003OJ\u2003\u2264\u20036.0\u2003mm with competent lips, 3.5\u2003mm\u2003&lt;\u2003OJ\u2003\u2264\u20036.0\u2003mm with incompetent lips and OJ\u2003&gt;\u20036\u2003mm. Samples were also subdivided into two groups: OJ\u2003\u2264\u20033.5\u2003mm and OJ\u2003&gt;\u20033.5\u2003mm. Chi\u2010square test was performed to determine any gender differences in trauma experience. Logistic regression was performed to test for any differences in risk of MIT in different groups, and to estimate the predictive value of facial skeletal pattern (sagittal), FMPA, gender, OJ, and lip competence for MIT. <jats:italic>Results<\/jats:italic>: Nine percent had incisor trauma (8.4% MIT). Boys had greater odds of receiving MIT than girls (OR\u2003=\u20032.16; 95% CI, 1.11\u20134.21). Subjects with Class II skeletal patterns had greater odds of MIT than those with Class I skeletal patterns (OR\u2003=\u20033.98; 95% CI, 1.98\u20138.00). Subjects with decreased FMPA had greater odds of MIT than subjects with average FMPA (OR\u2003=\u20034.55; 95% CI, 2.28\u20139.06). Lip competence was not associated with MIT (<jats:italic>P<\/jats:italic>\u2003&gt;\u20030.05). Subjects with OJ\u2003&gt;\u20033.5\u2003mm had greater odds of MIT than subjects with OJ\u2003\u2264\u20033.5\u2003mm (OR\u2003=\u20032.83; 95% CI, 1.49\u20135.37). <jats:italic>Conclusion<\/jats:italic>: Compared with children with normal OJ (\u22643.5\u2003mm), Class I skeletal pattern (Straight profile) and average FMPA, the odds of MIT increased significantly in children with OJ\u2003&gt;\u20033.5\u2003mm (OR\u2003=\u20032.83), Class II skeletal pattern (OR\u2003=\u20033.98) and decreased FMPA (short face profile) (OR\u2003=\u20034.55),
