Mohit Chaturvedi, Neha Chaturvedi

Background: Malocclusion is a problem since old times. It is more severe in developing countries like India which causes problems to the oral health and leads  to social and the psychological problems. The purpose of the study was to determine the prevalence of malocclusion in permanent dentition among adolescents. Material and methods: This cross-sectional study was conducted over the period of 1 year in a sample size of 140 adolescents’ age 13-16 years. Before the beginning of study, a written informed consent was obtained from the participant’s parents. Adolescents undergoing orthodontic treatment or with a history of previous orthodontic treatment, previous history of permanent teeth extraction, and craniofacial deformities or syndrome were not included in the study. The occlusal parameters recorded by examiners include molar and canine relationship, overbite, overjet, anterior open bite, spacing, crowding, anterior crossbite, scissors bite, and posterior crossbite. Statistical analysis was done by using SPSS, version 22 (SPSS, Inc., Chicago, IL) and p<0.05 was considered statistically significant. Results: In our study a sample of 140 participants of age 13- 16 years were selected in which 74 were males whereas 66 were females. A symmetric Class I molar relationship was found in 57.14% of the participants; Class II was found in 9.28% and Class III in 14.28%. The most common canine relationship was symmetric Class I followed by symmetric Class II and Class III, which were observed in 51.42%, 15%, and 13.57% of the sample, respectively. The study showed that 69.28% had overjet between 1-3 mm, 90% had overbite with 1-3 mm overlap, Open bite was present in 4.28% participants between 1 and 3 mm, Anterior cross bite was present in 8.57% while the unilateral and bilateral posterior cross bite were found in 9.28% and 1.42%, respectively. Scissors bite was not present in any participant. 17.85% and 15.71% of the participants had crowding in the anterior segments of the maxilla and the mandible, respectively, crowding was present in the posterior segments with 4.28% of the participant in the maxilla and 3.57% in the mandible, 17.85% of the participants had spacing in the anterior segment of the maxilla and 9.28% in the anterior segment of the mandible. Conclusion: In our study, class I molar and canine relationship are more prevalent with normal overjet, and normal overbite. Crowding is more prevalent than spacing followed by increased overjet, and increased overbite, posterior crossbite, anterior open bite, and anterior crossbite.
