Dental Anomalies in Individuals with Treacher Collins Syndrome – Tomographic Analysis - Abstract
The Treacher Collins syndrome is a genetic disorder with prevalence of 1:50,000 livebirths, characterized by multiple craniofacial deformities, requiring high-complex and multidisciplinary treatment. This study analyzed the occurrence of dental anomalies in individuals with Treacher Collins syndrome, by analysis of computed tomographies obtained before orthodontic or surgical treatment, to analyze the dental findings associated with the syndrome. The study was conducted on computed tomographies of 42 individuals, among which 20 were excluded according to the study criteria, 4 had no alterations, and 18 individuals presented dental anomalies. There was high prevalence of anomalies of number and position, especially hypodontia (23.8%) and rotations (23.8%).
