Included in a handbook are discussions on general information for dental health for the institutionalized retarded, their need for dental care, the attendant's role in providing care, dental information for the attendant, how and when to use a toothbrush, care of toothbrushes and equipment, and indications of abnormal mouth conditions. Information is also presented on the development of programs of dental care according to cottages or wards of residents who can brush on their own, who can partially brush, or who are incapable of brushing. Recommendations for a successful dental program are outlined; photographs and charts are used throughout. (JM)
