Abstract
OBJECTIVES: To investigate the prevalence and gender distributions of dental anomalies in French orthodontic patients. MATERIAL AND METHODS: A retrospective review of the dental files of orthodontic patients was conducted to investigate the frequencies of dental anomalies. Pretreatment intraoral photographs and panoramic radiographs were analyzed. The occurrence rates of various dental anomalies (as determined by the numbers, shapes, structures, exfoliations, and eruptions of teeth) were calculated as percentages and differences in gender distribution using Chi2 and Fisher tests. RESULTS: Five hundred fifty-one patients receiving orthodontic treatment between 2003 and 2013 at a French hospital were included in the study: 45.74% of the patients (n=252) presented at least one dental anomaly. Taurodontism was the most common (15.06%), followed by ectopic eruption (11.43%). Odontoma, macrodontia, fusion, gemination, talon cusp, dentinogenesis imperfecta, regional odontodysplasia, premature tooth eruption, and premature exfoliation were not found. No statistically significant correlations were found between gender and the occurrence of dental anomalies. CONCLUSION: French orthodontic patients exhibit a high rate of dental anomalies, indicating that dental anomalies should be carefully considered in the orodental management of French patients.
