ObjectiveThe objective of this study was to investigate the prevalence of dental anomalies in individuals with Richieri-Costa-Pereira syndrome.Study DesignA total of 13 individuals with Richieri-Costa-Pereira syndrome who were older than 8 years with at least 1 available panoramic radiograph were assessed. Dental anomalies were evaluated clinically and radiographically and classified as hyperplastic, hypoplastic, or heterotopic and as alterations of shape, number, position, and structure. Enamel alterations were classified by the DDE index.ResultsAll individuals exhibited anomalies, with predominance of hypoplastic disorders, mainly agenesis of mandibular incisors and second premolars and demarcated creamy-white enamel opacities primarily affecting the maxillary premolars.ConclusionsIndividuals with Richieri-Costa Pereira syndrome exhibit high prevalence of tooth agenesis, especially mandibular incisors and premolars, as well as high frequency of enamel opacities. These findings are compatible with the mandibular cleft observed in all individuals and also reflect the hypoplastic characteristic of the syndrome.Copyright © 2012 Mosby, Inc. All rights reserved.
