Prevalence of Tooth Transposition, Third Molar Agenesis, and Maxillary Canine Impaction in Individuals with Down Syndrome

摘要: Abstract Alterations in the size, morphology and number of teeth are among many inherited disorders that have been reported individuals with Down syndrome. By contrast, third molar agenesis tooth transposition largely ignored prevalence canine impaction has not reported. The intention this study was to quantify occurrence these anomalies a group syndrome, using standardized records, which included clinical examination, dental casts, panoramic radiograph. results show notably high (74% older than 14 years), (15%), maxillary canine/first premolar compared published figures from random population samples. These should be seen as separate, independent entities, but associated phenomena. slow rate cell growth consequent reduced characterize syndrome may responsible for un...
