Abstract
The primary purpose of this study is to present the differences of the dental caries incidences among types of the mentally retarded. The secondary purpose is to investigate the important influencing factors and a possible correlation between the oral conditions and these factors.
Dental examinations and caries activity tests, by glucose clearance rate and Resazurin disc, were performed on 267 mentally retarded children and 120 normal children ranging in age from 10 to 13. Additionally, a survey was taken by questionnaire in 212 handicapped children and 118 normal children. The following observations were made.
1. Comparing with the control group, the degree of dental caries incidence was higher in the simple mental retardation group(p<0.01) and lower in cerebral palsy group(p<0.01). Significant differences were not found between the other groups (p)0. 05) .
2. All the handicapped groups showed higher plaque indices than the normal group (p<0.01). Significant (p<0.01) correlations (r)0.2) were observed between the plaque indices and caries experiences.
3. All the handicapped groups showed longer glucose clearance time and higher R. D. scores than the normal group. However no significant relationship was observed between the caries prevalence and both the glucose cearance rate and the R.D. test.
4. The institutionalized children had lower incidence of caries than the non-institutionalized children.
5. Among several environmental factors, diet habit was the most significant factor.
