DIFFERENT TYPES OF MALOCCLUSIONS AND TREATMENT NEEDS AMONG ORTHODONTIC PATIENT: AN INSTITUTION BASED STUDY

The aim of this study was to analyze the different types of malocclusions among patients who visited Department of Orthodontics and Dentofacial Orthopedics of Narsinhbhai Patel Dental College and Hospital, Visnagar, Gujarat as a baseline data for proper treatment planning, teaching and further research. Materials and methods: This study was conducted on 154 patients who attended the Department of Orthodontic and Dentofacial Orthopedics from June 2012 to August 2015. Information regarding age, sex, type of malocclusion, dentofacial patterns and dentofacial characteristics was obtained from patient records. Orthodontic treatment need was assessed using DHC component of IOTN. Results: The results of the study showed that the patients age ranged from 9 to 35 years with mean age of 18 years 7 months. There were 86 (55.8%) males and 68 (44.1%) females. Chief complaints of majority of patients were ‘irregular teeth’ and ‘upper front teeth forward’. The commonest type of malocclusion was Angle’s class II which was seen in 79 (51.3%) of patients. There was an increased overjet in 78% of subjects. Statistically significant association was found between skeletal and Angle’s classes (p < 0.0001). Assessment of need for orthodontic treatment using the DHC component of IOTN showed that 41 (26.6%) were in moderate need of treatment, 56 (36.3%) had severe need of orthodontic treatment, and 31 (20.1%) had extreme need of treatment. Conclusion: The results gave a detailed pattern of malocclusion in orthodontic patients and the commonest type of malocclusion was Angle’s class II div1 and this may provide a baseline data for research and planning orthodontic services.
