Pattern of Malocclusion in Patients undergoing Orthodontic Treatment at a Tertiary Care Teaching Hospital

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.

Pattern of malocclusion in orthodontic patients at a tertiary care centre

“…9 In the current study, a higher proportion of females (68.5%) received orthodontic treatment than males (31.5%). This study is in accordance with the two different studies done in Biratnagar, Nepal which showed females (69.33%) 16 and (70%) 8 were more concerned about orthodontic treatment than males. Similarly, a study done at Dharan, Nepal also showed females (69.7%) were more concerned than males (30.3%).…”

“…Angles Class III malocclusion (male 3 and female 3, equal in number) was seen only in 13 years and above age group, which could be due to a higher number of patients in this study. Here, the association of Angles malocclusion with gender and age group was insignificant, which was similar to other studies 12,13,18 done before but contrary to study, 8 where the distribution of malocclusion and age was significant.…”

“…7 A study in Biratnagar, Nepal showed female (70%) patients had more malocclusion compared to males. 8 The prevalence of malocclusion varies among different populations of the world. Many etiological factors for malocclusion have been proposed, among which genetic, racial, and environmental aspects are the major contributors.…”
