Abstract

Abstract: Aim: In the present study, we investigated the characteristics and sequelae of erupted supernumerary teeth (ST) in a sample of Sri Lankan children. Methods: Data were recorded from patients' clinical records, radiographs, models, and extracted teeth. Results: The sample consisted of 239 ST from 218 patients. The mean age of the sample was 9.08 ± 2.47 years. The male‐to‐female ratio was 2.8:1. The majority (42.66%) of patients with ST were in aged 8‐10 years. Many (94.94%) of the ST were located in the premaxilla (incisor), followed by the canine (4.22%), premolar (0.42%), and molar (0.42%) regions. The most common shape of ST teeth was conical. Malocclusion (59.83%) was the major problem associated with ST, and the clinical impact was highest on the 8‐10‐year age group. A strong association was observed between patients' age and clinical impact to the dentition (χ 2 =42.09, P =.000). Conclusion: Because the majority of ST can lead to malocclusion, especially in mixed dentition, awareness, early detection, and timely clinical intervention of ST are recommended.
