Abstract

Introduction: Hyperdontia or Supernumerary teeth might be associated with disorders in teeth, occlusion and esthetics. This study was undertaken to investigate the Prevalence andposition of Supernumerary teeth in different types of Malocclusion amongorthodontic patients. Materials& Methods: In this retrospective descriptive study, 102 patients (males and females) withhyperdontia who were referred to a private clinic for conventional dentalexamination, counseling or performing orthodontic treatment from 2008 to 2016, were identified. The Supernumerary teeth were recorded in terms of presence, number, shape and location (maxilla or mandible) using panoramic radiographs. Malocclusion type of the patients was also classified into types I, II and III andrecorded. Data were analyzed with SPSS 20, using chi-squared test (α = 0. 05). Results: The Prevalence of Supernumerary teeth in males was significantly higher than that infemales (p value = 0. 036). Maxilla had a higher incidence of Supernumerary teeththan mandible (p value < 0. 001). The Prevalence of Supernumerary teeth was notsignificantly different between different classes of Malocclusion (I, II and III). Crowding (22. 5%), impaction (21. 6%) and malposition adjacent to supernumeraryteeth (5. 9%) were the most frequent abnormalities associated with Supernumerary teeth. Conclusion: The results of the present study are generally consistent with those reported in theliterature. However, there are a few differences that might be due to racial andenvironmental differences. The Prevalence of Supernumerary teeth in our patientswas low, and it was more prevalent in males and in the mandible. In addition, it wasnot related to the type of occlusion of the patients.
