Cephalometric measurments of a Saudi adult sample according to Jarabak's analysis

ABSTRACT

The aim of this study was to establish cephalometric norms of Saudi adults according to Jarabak's analysis and to evaluate whether a significant difference exists between Saudi measurements and Jarabak's norms. The inclusion criteria were normal occlusion, pleasant soft tissue profiles, no history of trauma, and no previous orthodontic treatment. The study was carried out on sixty-two standardized lateral cephalometric radiographs of 31 female and 31 male Saudi adults with a mean age of 23 +/- 1 years. Descriptive analysis and independent Student's t-test were carried out. The results showed statistically significant differences in the anterior cranial base length, mandibular length, lower gonial angle, and posterior facial height [p < 0.05] between the Saudi males and females when compared to Jarabak's norms [p < 0.05]. The results demonstrated that the Saudis have distinct cephalometric facial features. It can be concluded that Saudi males and females have distinct craniofacial features when compared to Caucasians. These distinct features should be considered when orthodontists and orthognathic surgeons set their treatment objectives:
