Objective: Supernumerary teeth result from disruptions in dental lamina development during odontogenesis. This study aimed to investigate their prevalence, demographics, and clinical features (number, location, morphology, eruption, position) in children aged 5-12 years via panoramic radiograph analysis.
Methods: This retrospective cross-sectional study analyzed 7,085 anonymized panoramic radiographs (2019-2020) from Gaziantep University. Data included age, sex, supernumerary tooth number, location, morphology, eruption status, and position. Odontoma cases were excluded. SPSS 22.0 was used for descriptive statistics, Pearson’s chi-square tests, and reliability analyses (p<0.05).
Results: Prevalence was 1.73% (123 patients) among 7,085 children. Mean patient age was 9.31±1.73 years (5-12 years), with a male-to-female ratio of 1.86:1. Most patients (82.11%) had one supernumerary tooth, 16.26% had two, and 0.81% had three or four. Teeth were mainly located in the premaxilla (89.18%). Morphologically, 66.21% were conical, 20.27% supplemental, and 13.51% tuberculate. Most were impacted (70.27%) and vertically oriented (67.56%).
Conclusion: These findings highlight the critical need for early diagnosis and personalized treatment to prevent complications and reduce future complex interventions.
