Abstract
Most orthodontists and clinicians used to evaluate the patient's profile, clinically and radiologically. To obtain a correct diagnosis, most clinicians now realize the importance of an appraisal of the patient's facial esthetics from the frontal and lateral aspects. He aim of the present study is to establish the cephalometric mandibular norms of Iraq adults (18-25 years) by means of linear and angular analysis of PA and LAT cephalometric radiographs. The sample is collected from the students of Mosul University and is consisted of 100 Iraqi adults (50 males and 50 females) aged (18-25 years) with class one normal occlusion. LAT and PA cephalometric radiographs are taken for each subject, Twenty seven cephalometric measurements (11 angular and 16 linear measurement). Statistical analysis of data is done by using computerized statistical program Minitab. The angular measurements of the mandible showed that the females are significantly larger than males in the N.S.Ar, SN-MP, SN-Occ and B.Me-MP, where as the S.N.B., S.N.B., S.N.Pog and S.N.Id are significantly larger in the males, and the rest of the angular measurements show no significant difference between the two sexes. All the linear measurements of the mandible for males are significantly larger than the females.
