Objectives: The aim was to assess and compare the prevalence of orthodontic treatment need among various special health care needs (SHCN) schoolchildren and adolescents in Dharwad, India. Materials and Methods: This cross-sectional study was carried out among 492 subjects in age group of 12-19 years (mean age 14.02 ± 1.84 standard deviation [SD]) who were examined for occlusal anomalies using dental aesthetic index (DAI). They were classified into five groups as: Visual impairment, speech and hearing disability (SH), physical disability, mentally subnormal and multiple disabilities (MD). Chi-square test was used to compare the orthodontic treatment need among various SHCN groups. One-way ANOVA and ANCOVA were performed to test any significant differences in mean DAI scores among the SHCN groups. Results: None of the children were undergoing or had undergone orthodontic treatment for malocclusion. Mean DAI score was 28.81 ± 11.64 (SD). Orthodontic treatment was indicated in 50.2% of study population who had DAI scores of 26 and above. Mandatory orthodontic treatment (DAI >=36) was required in as high as 29% of MD individuals when compared to only 10% of SH individuals. Significant differences in DAI scores were found between the SHCN groups. Conclusions: The need for orthodontic treatment among SHCN individuals was found to be high. Yet, absence of any orthodontic treatment for any child points out to the fact that the dental services are highly needed in these individuals.
