Soft Tissue Cephalometric Standards for a Moroccan Teenage Population

Objectives: The goal of this study was to assess the soft tissue measurements of Moroccan adolescents with balanced facial profile and correct occlusion and to compare them with other ethnicities norms. Methods: The material included the lateral cephalometric radiographs of 64 patients, 30 boys and 34 girls, aged between 14 and 18, with correct occlusion, balanced facial profile, and no subsequent orthodontic treatment. Seven reference lines were identified and traced, on each radiograph, according to Ricketts and Holdaway norms. Twelve linear and 2 angular measurements were analyzed. Results: Only the H angle shows a significant difference between boys and girls in our sample. The standards set on the American population and the jordanian one showed several statistically significant differences in comparison with ours. Conclusion: The results of this study show several differences between the Moroccan soft tissue profile norms and those of their American and jordanian counterparts and strength the idea that the norms of a specific population should be used as a reference for a successful orthodontic treatment
