In mentally handicapped individuals, attention paid on their oral health is usually insufficient. This population is edentulous or partially edentulous, with high rate of dental caries and periodontal disease, and without adequate prosthetic constructions. Oral examination was done in 70 female residents of 'Centre for mentally handicapped women' in Višegrad (Bosnia and Herzegovina). Before the clinical examination, mini mental test (Mini Mental State Examination) was used for the quick orientation about degree of mental disorder. Finally, the plan of dental rehabilitation was made according to patient's health condition and mental diagnosis. All examined patients had severely damaged oral functions, including periodontal disease, decayed roots and a great number of missing teeth. Not a single patient had prosthetic constructions. Patients with lower degree of mental disorder showed satisfactory cooperation and it was estimated that dental treatment could be under- taken in these individuals. Mentally handicapped patients show high need for dental treatment. Prosthetic rehabilitation is possible in some of mentally handicapped patients.
