This study aims to evaluate the prevalence and patterns of supernumerary teeth in a Peruvian nonsyndromic population. This retrospective study used 2500 panoramic radiographs from the archives of a radiology center from Tacna-Peru. Radiographs were taken in 2019 and corresponded to subjects with ages between 8 to 22 years. The patterns of the supernumerary teeth were recorded in a checklist. Descriptive statistics was used for the distribution of supernumerary teeth. The Chi-square test was used to compare the distribution between the patterns. A confidence level of 5 % was used. The prevalence of supernumerary teeth was 5.32 % (n=133), with a male: female ratio of 1.56:1. The most affected arch was the maxilla (79.7 %), single presentation was the most common (87.22 %), and no differences were observed by gender ( p > 0.05). Mesiodens was the most frequent (53.38 %), followed by parapremolar (34.59 %) in both genders (p > 0.05). According to the morphology, conical presentation was presented in 46.62 % of the cases, and impacted status were seen in 69.92 %. There were significance differences when the distribution of morphology was compared by the affected arch (p < 0.05). Conical form was most common in the maxilla (53.77 %), meanwhile in the mandible was the euromorphic type (40.74 %). A prevalence of supernumerary teeth of 5.32 % was estimated. The most frequent affected arch was the maxilla. Mesiodens, conical type and impacted were the most frequent patterns.
