Abstract OBJECTIVES: Malocclusion plays an important role in the overall oral health of an individual because it is associated with periodontal disease, temporomandibular disorders and may be complicated by an individual's disparity. Careful attention to malocclusion in children with special needs leads to a considerable improvement in the quality-of-life. The objective of the present study was to analyze the prevalence of malocclusion and its association with determinant factors in individuals with special needs in South India. MATERIALS AND METHODS: A cross-sectional study was carried out that included 844 individuals with special needs and their mothers at eleven institutions in South India. Data were collected based on the questionnaire given to the mothers and dental examination carried out on the children. The nutritive and non-nutritive oral habits were obtained from the reports of the mothers. Clinical examination recorded the following: Class I, Class II, Class III, anterior crowding, anterior spacing, deep bite, open bite, and anterior cross bite. Statistical analyses of data were performed using Chi-square test. RESULTS: Results at the end of the study revealed anterior crowding in 27.37\% of the total sample size, deep bite in 20.5\%, Class I in 14.34\%, anterior spacing in 12.9\%, Class II in 9.95\%, Class III in 5.33\%, anterior cross bite in 4.98\% and open bite in 4.62\%. CONCLUSION: The prevalence of malocclusion in individuals with special needs is associated with the type of disability and it is more in males than females. Mentally disabled individuals had higher frequencies of all types the malocclusion. Prevalence of anterior crowding was higher compared to other types of malocclusion followed by deep bite.
