[Statistical studies on caries in handicapped children].

The prevalence of caries in 108 mentally and physically handicapped children between the ages of 6 and 16 was determined in a clinical study. The prevalence of caries in residual teeth was extremely high, 100% higher than in the healthy control group. Caries-free dentition was not observed. The oral hygiene was totally inadequate in 94% of the children examined. The state of dental care for these patients was unsatisfactory. It was shown that directed prophylaxis is a necessity with handicapped children.
