Efforts to improve the quality of life of handicapped people are on the increase world wide, their oral health inclusive. Relevant data is required for adequate planning for this purpose.

A survey of 579 handicapped children was carried out in Lagos to assess the various dental abnormalities among them. Over 34% of them had various dental abnormalities, the most commonly encountered being enamel hypoplasia which constituted 12.3%, and more than half of which was chronologic (58.9%). This was predominant among the mentally handicapped (13.5%) and the blind (12.5%). Tetracyline staining was also a common finding particularly among the blind subjects (15.6%).

Spacing and crowding of the teeth were common in Angle's Class I malocclusion in all the handicap groups.

It was found that most of these abnormalities were linked to the cause of the handicaps or as a result of the handicaps.
