health in Indonesia. Dental and oral health in children is an important factor that must be considered as early as possible.

Down Syndromeis a chromosomal disorder thatresults in mental retardation. Mental retardationis a worldwide problem with major implications, especially for developing countries. It is estimated that the incidence of severe mental retardationisabout 0.3% ofthe total population, andnearly 3% havean IQ below 70%. As human resources, ofcourse they cannot be utilized, because 0.1% of these children need care, guidanceandsupervisionthroughouttheirliving.Objective: To review the frequency of malocclusion in DownSyndromechildren. Methods: Scientific evidence and clinical cases were drawn from the literature to support this review and information on the frequency of malocclusion in childrenwith Down Syndromewascollected.Result/Discussion: There are several types of malocclusion that often occur in children with DownSyndrome. Some of them are associated with class III Anglemalocclusion, crowding, and anterior open bite. Conclusion:Down Syndrome is one of the most studied genetic syndromes because of its frequency in our population and its medical significance. Malocclusion was observed in 92% of subjects with Downsyndrome. The incidence of malocclusion is higher in children/adolescents with Down Syndrome than in individuals without the syndrome. Class III malocclusion is most frequently observed.
