Abstract
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.
Highlights
Malocclusion can cause dental caries, periodontal disease and aesthetic problems
The inclusion criteria were: i) Patients undergoing orthodontic treatment with veritable pretreatment records; ii) Individuals residing in province one region of Nepal; iii) Subjects with permanent dentition and fully erupted permanent first molar; and iv) Patients should be aged from 1255 years
The present study shows the distribution of malocclusion on the basis of Angle’s classification which revealed 167 (59.65%) of Angle’s class I (Table 1)
Summary
Malocclusion can cause dental caries, periodontal disease and aesthetic problems. Malocclusion is the most common dentofacial abnormality found in human population. Malocclusion, defined as an improper relationship between teeth in the opposite jaws, has been a prevalent disorder in recent decades.[1] As stated by Angle “occlusion is the normal relation of the occlusal planes of the teeth when the jaws are closed” and malocclusion as per Dental Practice Board is justified as an abnormal occlusion, in which teeth are not in a normal position in relation to adjacent teeth in the same jaw and/or the opposing teeth when the jaws are closed.[2]. Knowledge about the distribution of different malocclusions may help orthodontic practitioners in better understanding of the extent of malocclusion problem in a geographic location and help them in the proper orientation and management of treatment possibilities.[3] There have been several studies investigating the prevalence of Correspondence Citation.
