Abstract

BACKGROUND: The prevalence of supernumerary teeth in different countries of America, Europe and Asia ranges between 0.3 and 3.8%. It is unknown about the prevalence of supernumerary teeth in Ecuador, therefore, the references in South America are taken from Brazilian populations. OBJECTIVE: To determine the prevalence and possible etiological factors of supernumerary teeth in the pediatric section. MATERIALS AND METHODS: It is an observational, analytical and descriptive, cross-sectional study. The sample consisted of 1205 medical records from 2015 and 2016 obtained from two pediatric dental areas. RESULTS: 31 patients with supernumerary teeth were found of which, 61% were male and 39% female. The upper jaw represented 87% of the cases and the mesiodent 94%, as well as the conoid morphology represented the 84% and its high relation with the central ones gave a 77% in relation to the cases. Regarding the pathological antecedents, 58% of the patients have relatives of first degree with history of supernumerary teeth CONCLUSION: this study demonstrated that the prevalence of supernumerary teeth in an Ecuadorian pediatric population is among the international averages and that: the male sex, the mesiodent, the conoid morphology, the upper jaw and the central ones occur more frequently.
