Abstract

Introduction: Present study focuses in an insight into the prevalence and severity of different malocclusions in differentially abled children and adolescents and assessment of treatment needs using IOTN index.

Methodology: The mean age of the evaluated students (n=171) was 15.2+/- 1.6 years, with 79.3% ranging from 12 to 17 years old. Randomly selected sample consisted of mental retardation, locomotor disabled, speech disabled, vision disabled, hearing disabled and syndromic. Prevalance and treatment requirement was determined using six malocclusion parameters. Statistical analyses were carried out by using SPSS (Version 11.5, SPSS, Chicago USA). Chi-square test was used to determine if there were significant differences in the distribution of orthodontic problems according to age and sex of students.
Results: Chi Square value (p < 0.05) for six disabilities does not show a significant difference between male and female patients. No significant difference was observed between male and female patients in relation to prevalence of Class I, II & III malocclusion among loco-motor disability, vision disability, hearing disability and syndrome disability groups. Contrary to this, statistically significant difference was observed between male and female patients with respect to presence of Class I, II & III malocclusion among mentally retarded and speech disabled group. Chi square values (p < 0.05) for distribution of Altered Eruption, Impaction, and Cleft among six groups of disabilities do not show a significant difference between male and female patients. Treatment need score of six group of disabilities ranged from 3 (borderline need) to 5 (definite need) irrespective of age and sex.
Conclusion: Differentially abled children definitely have special orthodontic need in comparison to their normal counterparts and require similar attention and treatment without prejudice and discrimination.
