Cephalometric Norms in Sudanese Sample: A Pilot Study

Abstract

Aims: In this study, cephalometric norms for Sudanese with class I normal occlusion were introduced, and the results were compared to those from other studies in various populations. Materials and Methods: 29 cephalographs with ages ranging from 18 to 25 made up the sample. The selection criteria were met by all competitors. After that, cephalometric findings were compared to earlier findings from research among reported Arabs, as well as research among Oriental and Black races. Results: When compared to Caucasian cephalometric norms, Sudanese showed greater mean values of the sagittal and vertical relationships. The inter-incisal angle decreased, and the upper and lower incisors were proclined in reference to their dental bases. The soft tissue variables show that the nasolabial angle was less acute and that the lips were slightly protruding in relation to Rickett's esthetic line. Black and Oriental races, as well as Arab populations possessed bimaxillary proclination and protrusion of the upper and lower incisors, whereas Caucasians had retrusive dentition. Conclusion: Due to the small sample size, drawing a firm conclusion is challenging. Therefore, it is advised to use large sample sizes for both sexes in order to establish cephalometric norms, which will be very beneficial to not only orthodontists but also oral and maxillofacial surgeons, as well as pedodontist.
