Cephalometric norms for a Moroccan population

Abstract

This is a descriptive cephalometric study aimed at contributing to the establishment of Steiner analysis cephalometric norms for a patient population from the Center for Dental Treatment and Consultation (CCTD) at the Ibn Rochd Hospital Center in Casablanca, Morocco. Teleradiography was used to obtain lateral cephalograms of 71 young adults (47 women; 24 men) aged on average 22.73 ± 1.69 years. All subjects presented good facial harmony, an acceptable profile, and dental class I with no history of orthodontic treatment. Tracing and analysis followed. The resulting means and standard deviations were compared to Steiner's norms and norms from similar studies. This revealed certain particularities in our sample, the most notable being a greater skeletal sagittal discrepancy (indicating a class II tendency), labial crown tipping of the lower incisors, and a retruded position of the maxillary and mandibular bony bases. These features should be taken into account when diagnosing and treating patients at the CCTD. However, more exhaustive studies must be performed before these results can be generalized to the Casablancan or Moroccan populations as a whole.
