Occurrence of hypodontia, supernumerary teeth and dental anomalies in Brazilian individuals with Down syndrome

Abstract Aim and objectives: Oral manifestations of Down syndrome include large and fissured tongue, arched palate, micrognathia, open bite, angular cheilitis, malocclusion, bruxism, low incidence of caries, spacing of teeth, delayed eruption, periodontal disease and dental anomalies. Design: This study evaluated the occurrence of hypodontia, supernumerary teeth and dental anomalies in 96 Brazilian individuals with Down syndrome by using clinical and radiographic examinations. Results: Hypodontia was the most prevalent condition (35.4%), followed by microdontia (9.4%) and conical teeth (7.3%). Taurodontic teeth and tooth transpositions were observed in 3.1% of the patients, while invagination, hypomineralisation of enamel, and tooth fusion occurred in 1.1% of the cases. Among the individuals presenting dental anomalies of size, shape or position, the majority of them (23.9%) exhibited only one affected tooth. Conclusions: The occurrence of hypodontia, supernumerary teeth and dental anomalies in individuals with Down syndrome is high, and early detection of these conditions allows for dental treatment to be adequately planned. Also, a comprehensive radiographic examination should be indicated for all children with Down syndrome.


Key words: Down syndrome, dental anomalies, supernumerary teeth, hypodontia, taurodontic teeth
