Aim: The present cross-sectional study was conducted to determine the decayed, missing, filled primary and permanent teeth (dmft-DMFT) indices and its association with the type of disability in 856 disabled individuals attending special schools in twin cities of Hyderabad and Secunderabad, Andhra Pradesh State, India. Materials and Methods: Participants were grouped according to their disability such as: Mild, moderate, severe mental retardation, hearing and speech defect and others (39) (including Down's syndrome [20], autism [9], hyperactive [4], microcephaly [2], border line cases [4]). Examination was carried out at their schools, with participants seated in ordinary chairs and examined under natural light with mouth mirror and probe. Subjects were of different age groups ranging from 1 to 55 years. Statistical Analysis Used: Analysis of variance with post-hoc Games-Howell test was used for statistical analysis. Results: Mean dmft; DMFT scores were as follows: 2-6 years: 1.58 ± 1.9; 2.18 ± 2.94, 7-12 years: 1.1 ± 2.4; 1.9 ± 2.13, 13-30 years: 2.38 ± 2.5, 30+ years: 2.13 ± 3.2. Overall only 23% of subjects were caries free. "dmft" was statistically higher among moderate mentally retarded group while DMFT was statistically higher in mild and moderate mentally retarded groups. Conclusions: These findings emphasize the need of educating parents and caregivers of disabled individuals in preventive dental procedures, especially those of the mild and moderate mentally challenged group.
