Title: Perception of Bimaxillary Dentoalveolar Protrusion Among a Sudanese Sample
Author: Hassan,Ammar Saad
Abstract: Bimaxillary dentoalveolar protrusion (BMDP) is a common presentation in orthodontic clinics in Africa including the Sudan. Patients with such a presentation are usually treated towards western population norms. The perception of the Sudanese people of different degrees of (BMDP) might have an impact on its treatment methods and results. Objective: The main objective of this study was to determine the degree of (BMDP) that is acceptable among a Sudanese sample. Materials and method: A total sample of 432 Sudanese, consisted of orthodontic patients (n =152), laypeople (n =266) and orthodontists (n =14). they were provided with a male and female silhouettes at 4 levels of protrusions to glabella perpendicular reference line. These levels were ;( S) =3mm, (Bi1) = 6mm, (Bi2) =9mm and (Bi3) = 12mm. The raters were asked to rank them in descending order of attractiveness. Results: (Bi1) female profile and male (S) profile were the most attractive profile as perceived by all raters. Laypeople subjects has significant ranking means differences from orthodontist and orthodontic patients in many profiles. No clear sexual dimorphism in perception of male and female profile except for a significant mean difference on ranking female profile (S) ( P = .031 ). Age has some influences on perception. Uneducated subjects showed frequent means differences compared to other educated subjects and also were inconsistent in profile ranking. Conclusion: There is a general agreement on the preference of male straight profile (S=3mm) and female ( Bi1=6) mm protrusion profile. Age and education has some influences on perception
