Abstract
Background/Objectives: The aim of this retrospective study was to investigate the supernumerary teeth located in the anterior region of the maxilla of non-syndromic Greek children and adolescents, as well as their possible correlation with demographic characteristics and radiographic findings. Methods: The study sample comprised cone-beam computed tomography (CBCT) scans from 224 children and adolescents aged up to 18 years. The following parameters were studied: location of supernumerary teeth in the anterior maxillary area, their morphology, their relationship to adjacent anatomical structures and adjacent teeth, and potential implications. Results: Out of the 224 cases 26 (11.6%) presented supernumerary teeth. There was higher prevalence in males than females (61.5% versus 38.5%, respectively). Among the 26 participants diagnosed with supernumerary teeth, one supernumerary tooth was found in 80.8% of children/adolescents, while 19.2% had two supernumerary teeth. The vast majority of supernumerary teeth were impacted (92.3%), and their morphology in 57.7% of cases was conical. A total of 38.5% of cases had normal orientation, 26.9% inverted orientation, 19.2% horizontal orientation, and 15.4% other. The localization was palatal in 84.6%, and the area of localization for 50% of cases was the midline. Conclusions: The prevalence of supernumerary teeth in the studied sample of Greek children and adolescents was 11.6% and tended to appear as single, impacted, conical, and with normal orientation. However, these results should be interpreted with caution, due to the limitations in the sampling strategy and the restricted generalizability of this study. The need for further research to enhance broader applicability for different populations is highlighted. These findings are instrumental for a more comprehensive understanding of the prevalence of supernumerary teeth, contributing to more accurate and individualized dental treatment planning in children and adolescents. This will help to avoid future issues in the patient's dentition.
