Pattern of malocclusion in orthodontic patients: A multi centre study. J Int Oral Health 2016;8(12):1105-1109. Abstract: Background: There has been a consistent effort and inclined interest of researchers to study varied patterns of malocclusion prevailing in various parts of India, yet the pattern of malocclusion of the orthodontic urban population in Odisha is not well known. The study aimed to ascertain the pattern of malocclusion and to provide quantitative information on the pattern of dentofacial characteristics among urban orthodontic population of Odisha. The objective of the study is to yield information about the variation in pattern and types of malocclusion in the urban orthodontic population in Odisha which in return would benefit the specialist to deliver quality treatment. Materials and Methods: A prospective hospital-based detailed investigation of 1 year was planned to include both male and female patients having permanent dentition in the age group of 12-30 years visiting the Department of Orthodontics of Kalinga Institute of Dental Sciences, Institute of Dental Sciences, Bhubaneswar and SCB Dental College, Cuttack, Odisha. The descriptive and inferential Pearson Chi-squared and Fisher’s exact tests were used to statistically justify the potential differences in the variation of malocclusion. Results: Out of 1207 subjects, 933 (77.3%) subjects were presented with Angle’s Class I malocclusion and 252 (20.88%) subjects were with Angle’s Class II malocclusion, whereas Angle’s Class III malocclusion was seen only in 22 (1.82%) subjects. Conclusion: Angle’s Class I malocclusion was the most predominant type of malocclusion in this population and Angle’s Class III being the least prevalent.
