The objective of this study was to determine the prevalence of dental anomalies in number in patients attending the Orthodontics Service of the Police National of Peru Dental Clinic in Angamos, Lima, from 2010 to 2016. The study was descriptive and retrospective. The sample consisted of 154 conventional and digital panoramic radiographs, clinical records, and orthodontic files, with ages ranging from 6 to 25 years. A data collection form was designed specifically for the objectives of the study. The results were analyzed using descriptive statistics with frequency analysis. The study concluded that the prevalence of dental anomalies in number was 38 cases (24.7%), with hypodontia found in 32 patients (20.8%) and hyperdontia in 6 (3.9%). The upper jaw was the most affected (47.37%), followed by the lower jaw (13.16%) and both jaws (13.16%). The most affected teeth by agenesis were the lower third molars (34.5%), followed by the upper third molars (30.9%). Canines were also among the most affected teeth by agenesis. Regarding hyperdontia, 7 supernumerary teeth were found, with 3 in the parapremolar region, 2 in the molar region, and 2 in the premaxilla (mesiodens and lateral). No cases of distomolar were found. Finally, regarding sex, it was concluded that males were more affected by dental anomalies in number with 22 cases (28.2%) and were the only ones with hyperdontia. No statistically significant differences were found. It is recommended that general dentists include this valuable auxiliary examination as part of a protocol, as it plays an important role in diagnosis and treatment.
