Prevalência e distribuição de dentes supranumerários numa população pediátrica – Um estudo radiográfico

Abstract

Aim The purpose of this study was to assess the prevalence and sex, arch and location distribution of hyperdontia through analysis of panoramic radiographs from a Faculty of Dentistry of University of Porto's pediatric population. Methods Panoramic radiographs of 1438 Faculty of Dentistry of University of Porto's patients (714 boys and 724 girls between the ages of 6 and 15 years old) were evaluated to determine the occurrence and distribution of supernumerary teeth. Chi-square and Fisher's Exact Tests were performed. The level of significance was set at 5%. Results The prevalence of hyperdontia was 2,8%. Most of the supernumerary teeth were found in the maxilla (82,5%) and mesiodens was the most detected supernumerary teeth (60%). There were no statistically significant differences between sexes. Conclusions The results are consistent with those previously described in different populations. By early identification of these anomalies, appropriate intervention may be planned, minimizing the complications associated with them.
