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: Many studies have been conducted in Iran to know the prevalence of malocclusions and orthodontics needs but no study so far has been conducted in Yazd.
Objectives: The aim of this study was to determine the prevalence of anterior open bite (AOBO) among 11 - 12 years old school-aging children in Yazd, Iran.
Patients and Methods: A total number 550 (278 boys and 272 girls) school aging children between 11 - 12 years old with permanent dentition were selected in this study from Yazd, Iran. The subjects were randomly selected, and none had received previous orthodontic treatment. Clinical examinations were carried out by one trained and calibrated examiner. The occlusal anteriorposterior sagital relationship were assessed based on the angle classification and also the vertical anterior relationship. The statistical software SPSS version 22 was used for the analysis different parameters as gender and age.
Results: AOB was present in 2.9% of subjects. 2.1% of the male and 3.6% of the females students in the sample were affected with anterior open bite. The prevalence of class I, class II and class III malocclusion with AOB was 1.7%, 3.2%, 21.4%, respectively.
Conclusions: This study shows that 2.9% of children examined had anterior open bite malocclusion which required treatment.

Background and aim: The aim of this study was determining the prevalence of malocclusion amongst the male adolescents of Yazd province and comparing the results with that of other provinces of Iran. Materials and methods: The sample of this epidemiologic study consisted of 1980 male students with age range of 14-17. The prevalence of class I, II, and III malocclusion according to the Angle’s classification was determined. Prevalence of Overbite, overjet, crowding and posterior crossbite was evaluated as well.Results: The prevalence of class I, II, and III malocclusion was 50.7, 19.5, and 16.6 percent respectively and normal occlusion was observed in 13.2% of cases. 47 percent of cases had normal overbite. Increased, reduced and edge to edge overbite was seen in 24, 11.9, and 13.1 percent respectively, and 4% had anterior open bite. Overjet was positive in 74.4% and negative in 12.4% of individuals. Prevalence of crowding and posterior crossbite was 40.5% and 10.5% respectively.
Conclusion: Class I malocclusion was the most common occlusal relationship in all of investigations done in different geographic districts of Iran. Clinical significance: Determining malocclusion prevalence in each population is prerequisite of making macro policy in health care systems, this study provides information about prevalence of malocclusion in Yazd province and comparing it with that of other geographical districts of Iran.

Aim: Cleft lip and palate is a social and functionally crippling problem. It is necessary to assess the degree of this problem in our society. The goal of thin study was to assess the number of cleft lip and palate patients in orthodontic patients reporting to Armed Forces institute of Dentistry (AFID), Rawalpindi, from 2001 through 2006.
Materials and Methods: 1118 consecutive patients reporting to AFID were included in the study. 18 were excluded based on inadequate records. Records were evaluated for the presence of clefts, impacted and missing teeth.
Results: 1% patients were found to have various kinds of clefts. 72.7% were female and the rest were male. Their mean age was 16.5 years. Bilateral clefts were more common. Reverse overjet and missing maxillary lateral incisors were strongly associated with cleft lip and palate.
Conclusion: Cleft lip and palate is reasonably prevalent in our society. Genetic predisposition and environmental factors are equally important in governing its occurrence. Both these issues have to be considered to reduce the incidence of this problem in a developing country such as ours WO 2006; 1:154-7).
