Objectives: The purpose of this study was to determine the prevalence of the dmft-DMFT indexes and the oral hygiene status of 136 individuals attending a special school for the disabled.Methods: Participants were grouped according to disability [Mental Retardation (MR), Cerebral Palsy (CP), Autistic Disorder (AD), Down Syndrome (DS), Other (OTH)] and age [2-6 years (n=24), 7-12 years (50 children) and 13+ years (62 children]. Caries examinations were carried out in accordance with WHO criteria and oral cleanliness was evaluated by visually assessing the presence of plaque on teeth.Results: The age range of patients was 2-26 years (mean age: 11.89±5.19 years). Mean dmft and DMFT scores by age group were as follows: 2-6 years: dmft=2.04±2.24; 7-12 years: dmft=2.24±2.60, DMFT=0.98±2.58; 13+years: DMFT=2.68±2.91. Overall, 15.4% of children had no caries or fillings. While dmft and DMFT levels (P>.05) did not vary significantly by type of disability, oral cleanliness did. Children with autism were observed to maintain the best oral hygiene and those with mental retardation (MR), the poorest.Conclusions: It is important for the dentist to concentrate on a preventive approach and provide proper dental education to parents of disabled individuals. Among the children with disabilities, more attention should be paid to the oral hygiene of MR group. (Eur J Dent 2010;4:361-366)
