Introduction: Anxiety is the state of feeling nervous or worried that something bad is going to happen. Dental anxiety is defined as a patient’s response to stress that is associated with a dental procedure. The aim of our study is to investigate the anxiety status of dental patients visiting Orthodontic department at Nobel Medical College Teaching Hospital, Biratnagar. Materials and Method: Total 80 ongoing orthodontic patients (M =21 F=59) who completed modified Dental Anxiety Scale questionnaire were included in the study. Result: Majority of patients (65%) had moderate anxiety where as 25% had mild anxiety and around 9% had severe to extreme anxiety. Patients’ age and education level had significant association with the level of dental anxiety. Conclusion: Dental anxiety in orthodontic patients is unavoidable but needs appropriate counseling. Orthodontist’s role is crucial in bridging the gap between patients’ perception towards orthodontic treatment and the actual treatment.

Introduction: Malocclusion can cause dental caries, periodontal disease and aesthetic problems. Malocclusion is most common dentofacial abnormality found in human population. However, the awareness for orthodontic treatment is increasing. Objective: The aim of this research was to evaluate pattern of malocclusion in patients undergoing orthodontic treatment at Nobel Medical College Teaching Hospital of Biratnagar, Nepal. Methods: Two hundred and eighty preoperative study casts (2018 Jun to 2020 Jun) of orthodontic patients aged from 12-55 years were selected from 680 patient’s records of department of orthodontics of Nobel medical college teaching hospital, Biratnagar. Standard protocol of Angle’s classification of malocclusion was used to classify malocclusion and its traits were recorded. Data were entered in Microsoft Excel and descriptive statistics were calculated. Results: The prevalence of malocclusion were 59.65% (167) of Angle’s class I, 35.71% (100) of Angle’s class II and 4.64% (13) of Angle’s class III malocclusion. Among various attributes of malocclusion, deep bite was the most common trait (188, 67.14%). Increased overjet was found in 169 (60.35%) subjects. Crowding and spacing were found in 164 (58.57%), and 109 (38.92%) respectively. Conclusion: Angle’s class I malocclusion is most prevalent malocclusion seen followed by Angle’s class II and Angle’s class III.

Introduction: Hypodontia or tooth agenesis is the most common developmental anomaly in craniofacial region. The multitude of problems in patients with hypodontia includes aesthetic, periodontal damage, malocclusion, inarticulate speech and alveolar bone deficiency. This commonly encountered condition in orthodontic department has variable site of occurrence, sometimes associated with syndromes.  Objective: To know the patterns and types of hypodontia in orthodontic patients attending orthodontic department at Nobel Medical College, Biratnagar. Methodology: Cross sectional study of 260 orthodontic patients’ pre-treatment records i.e., casts, orthopantomogram, lateral cephalometric radiographs and photographs were taken as study materials. Descriptive statistics was used to analyze the data and chi square test was used to find the level of significance among genders. Results: Congenital absence of one or more teeth was observed in 28 out of 260 patients, with a frequency of 10.8%. Among the hypodontia patients, 11 (4.23%) were males and 17 (6.54%) were females. Of all 69 missing teeth, the most (68%) was observed in class I group, and the least amount belonged to class III group (10%). Conclusions: The higher prevalence of hypodontia in Orthodontic patients in this region warrants careful inspection and investigation before embarking on the diagnosis and treatment planning.

Introduction: Various forms of malocclusion are a matter of serious concern in Nepalese population. This study was carried out to understand the prevalence of malocclusion among the school children of Biratnagar. The objective of this research is to find out the prevalence of malocclusion of children from different schools of Biratnagar visiting the Pedodontics and Orthodontics department of Nobel Medical College and Teaching Hospital, Biratnagar. Materials and Method: A descriptive cross sectional study method was used in this research. Data was collected by using direct observation of the subjects and occlusal assessment was done according to Angle’s classification and Dewey’s modification types of class I, class II and class III malocclusion. Result: Subjects with normal occlusion was found to be 39 % and with malocclusion was found to be 61%. Among them, class I malocclusion (60%) and angles class II div I subjects (88.33%) were in majority of the total study population. Conclusion: The present study helps to determine the prevalence of malocclusion and need of orthodontic treatment for the school children of Biratnagar
