Abstract
Orthodontic diagnosis and treatment planning require careful evaluation of the patient's cephalometric values and comparison to known population cephalometric means or norms. Despite the availability of several published studies on Saudi cephalometric norms, Caucasian norms are still referred to when Saudi patients are treated. To reach a consensus between these studies and to establish more accurately cephalometric norms for Saudis, a meta-analysis of the relevant literature was performed. Electronic database (PubMed), Saudi Dental Journal and Master theses were searched for studies reporting cephalometric values of normal male and female Saudi adults with numerical data and 8 studies with a total sample size of 485 met the inclusion criteria. A meta-analysis with results from these studies was completed. The combined mean estimates and SD of common cephalometric measurements were calculated. The data included in this comprehensive meta-analysis were compared with Caucasian norms and results indicated that Saudis have distinct cephalometric features. Saudis tend to have slightly more convex profiles and more proclined incisors than the Caucasians. These findings confirm the previously published results and should serve as more accurate reference values that were drawn from a large sample size.
