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.

Background: Following the morphological features of different races and ethnic groups, knowledge of standard dentofacial patterns of each ethnic group is essential. Therefore, this study aimed to explain cephalometric standards for the Zanjanian population according to Downs' analysis and compare them to Caucasian individuals.Methods: Seventy lateral cephalometries of Zanjanian adults (17 - 29 years old) who had been referred to a private orthodontic office in Zanjan, Iran with class I molar and canine relationship and normal overjet and overbite as well as minimum crowding/spacing/rotations were scanned and traced with the Novatech scanner and Dolphin software version 10. Next, statistical analyses were performed in order to compare the Zanjanian population to Caucasians. Results: We found a significant difference between males and females in terms of interincisal angle, incisor-occlusal angle, incisor-mandibular plane angle, upper incisor proclination, facial angle, and angle of convexity.Discussion: The analysis of six statistically significant parameters indicates that the upper and lower incisors in women of Zanjan were proclined and protruded compared with those of Caucasian subjects. Due to the statistical analysis on facial angle and angle of convexity, women also show more maxillary prognathism and skeletal class II pattern. Generally, a comparison of Zanjanian population cephalometrics based on Downs' analysis showed an increase in maxillary prognathism, maxillary and mandibular incisal protrusion and posterior rotation of the mandible.Conclusions: In conclusion, the Zanjanian population tends to have more dental and skeletal class II patterns than the Caucasians. In addition, gender comparison indicates lower and upper-incisors protrusion in women of Zanjan.

This article describes various aspects of risks and complications, commonly encountered in orthodontic treatment as a result of its materials, and also describes ways to minimize them in the course of orthodontic treatment. Although, like many other treatments, it has fundamental risks and complications. Thus, it is important to control the risks during and after orthodontic treatment (IJO 2006;1:198-202).
