Aim: BDD is a psychiatric diagnosis in the spectrum of obsessive compulsive disorder wherein the patient has a damaging mental preoccupation with a slight deficiency in his physical appearance. Awareness of this disease and its symptoms is essential for proper diagnosis and management of the patient.Methods: This cross-sectional study was performed on 86 patients who underwent orthognathic surgery. A demographic information questionnaire, Yale-Brown Obsessive Compulsive Scale modified for the BDD questionnaire, BDI-II questionnaire (Depression Scale) and Beck Anxiety Scale questionnaire were completed by patients to assess BDD disorder, depression, and anxiety. Data were described using appropriate statistical tables and graphs to express indicators and frequency distribution. Shapiro-Wilk, Mann-Whitney, Kruskal-Wallis, and Fisher tests were used to analyze the data.Results: This study was performed on 86 patients with a mean age of 23.19±4.5 years. The percentage of BDD in women (20%) was higher than in men (14%), but this difference was not statistically significant (p=0.685). The prevalence of depression was significantly higher (p<0.001) in patients with BDD (53%) than in those without this disorder (11%). The prevalence of anxiety was significantly higher (p<0.001) in patients with BDD (67%) than in those without this disorder (23%). With increasing age, the BDD scores decrease slightly, but this difference was not statistically significant (p=0.113).Conclusion: The prevalence of BDD in the study population was 17.4%. The high prevalence of the disorder in orthognathic surgery patients compared to the general population requires the serious attention of dentists to this disorder.

Aim: The purpose of the present study was to evaluate the accuracy of Dolphin Imaging version 11.8 software, in predicting soft and hard tissue changes after orthognathic jaw surgery.Methods: In this retrospective study, pre- and postoperative cephalograms and photographs of 20 patients were scanned and inserted into Dolphin Imaging version 11.8 software and traced by the software. Cephalometric superimposition was performed before and after the operation to determine the extent of changes in each jaw. The software then simulated postoperative images according to the calculated changes for each patient.Results: The results of this study showed that the upper lip had the highest accuracy in both sagittal and vertical axes. The highest reliability was in the upper lip with 80% error in the sagittal axis and the tip of the nose with 80% error in the vertical axis. The lowest accuracy in our study was related to soft tissue Menton which had the least reliability with an error frequency of 35% and 45% in the sagittal and vertical axis, respectively.Conclusion: Based on the method used and the findings obtained by digital measurements, it can be concluded that the Dolphin Imaging version 11.8 software can be used to reliably predict hard tissue as well as soft tissue, especially in the upper lip area.

Background: Severe skeletal class III malocclusions usually need a combined treatment of orthodontics and orthognathic surgery. Knowing about changes occurred following such treatments lead to improve facial esthetics and better treatment results.
Objectives: This study was done to determine cephalometric changes of facial soft tissue after combined treatment in patients with skeletal class III problem.
Methods: 25 patients with skeletal class III discrepancy who needed a combined treatment, were selected. Changes in nasolabial angle , upper lip and lower lip to E-line distance, angle of convexity , lip-chin-throat angle and lower anterior facial height were measured before and 6 - 12 months after surgery. Changes in parameters were analyzed with Paired t-test. Results: Upper lip to E-line distance (P < 0.0001) and angle of convexity (P < 0.001) changed significantly following surgical procedures while changes of other parameters were not significant.
Conclusions: Clinical changes in the soft tissue following a combination of orthodontic treatment and orthognathic surgery in patients with skeletal class III discrepancy are significant while these changes mostly improves esthetics of patient’s facial profile.
