    Abstract:
    Oral health disparities between individuals with disabilities and the general population are widely reported in the literature, and malocclusion is no exception. As the number of people living with disabilities grows, so does the need to explore their oral health status. This review examines the reported prevalence of malocclusion in individuals with Down syndrome (DS), cerebral palsy (CP), cleft disorders, mental disabilities, and physical disabilities from 1976 to 2004. Malocclusion was assessed according to Angle's classifications, the Dental Aesthetic Index (DAI), and selected occlusion characteristics. The prevalence of malocclusion was higher in individuals with disabilities than in controls without disabilities. Malocclusion was more frequent when the handicap was mental rather than physical in origin. Class II and Class III malocclusions were common in individuals with CP and DS, respectively. Crowding, anterior diastema, and >1/2 cusp antero-posterior molar relations were frequent among people with disabilities. Findings varied according to disability, but were attributed to musculoskeletal abnormalities, altered cranial-base relationships, premature tooth eruption, corrective surgery, and lip incompetence. Only a deep bite was more frequent in controls compared to the individuals with disabilities.
