Public Law 88-164, enacted in 1963, has led to extensive deinstitutionalization of persons with mental retardation from a peak census of 194,650 in 1967 to 91,440 by 1988. This population now depends on the community-based health care system for medical and dental care. A survey conducted to determine the availability of dental care to the developmentally disabled residing in group homes located in north central Florida indicated that 40% of caretakers experienced difficulty in locating dentists willing to provide comprehensive dental services for residents. According to the caretakers, although 75% of the residents were cooperative dental patients, dentists were reluctant to provide services for a variety of reasons, including financial disincentives, inadequate knowledge and preparation, and a lack of proper equipment necessary to treat this group of special patients.
