The aim of the study was to determine the oral health status and investigate the association of oral health status with various socio-demographic (age, gender, parents education, income) and clinical variables (aetiology for mental disability and IQ level) among mentally disabled subjects. The study sample comprised 225 mentally retarded subjects aged 12-30 years attending a special school in Udaipur, India. Caries status, oral hygiene status and periodontal status were assessed by DMFT Index, Simplified Oral Hygiene Index (OHI-S) of Greene and Vermillion and Community Periodontal Index, respectively. Chi-square test, one way analysis of variance (ANOVA), multiple linear stepwise regression analysis, and multiple logistic regression analysis were employed for statistical analysis. There was a statistically significant difference (P = 0.001) between all the age groups in all the variables of Oral hygiene index and DMFT index. The oldest age group had the highest scores for all the indices measured. Having Downs syndrome, parents with lower educational status and low I.Q. were the most important predictors for poor oral health status. The present study highlighted that the oral health status of this mentally retarded population was poor and was influenced by aetiology of the disability, I.Q. level, and parents level of education.
