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.

The objective of this research was to register the prevalence of oral mucosal lesions in patients treated at the Department of Stomatology of the Central Military Hospital of Peru during the period 2001-2016, and to determine the relationship concerning sex, age group, location, and etiopathogenesis. The population consisted of 27,350 clinical records from the years 2001 to 2016, and a formula was used to calculate the sample, resulting in 380 cases. The data were recorded in an Excel 2013 database and processed using SPSS version 21. The results showed a prevalence of 10.5% of oral mucosal lesions. The most prevalent lesion was the melanotic macule at 25%, followed by the traumatic ulcer at 20%, and frictional hyperkeratosis at 15%. Lesions were more prevalent in males with a male-to-female ratio of 1.6:1, and were more frequent in elderly patients (56-65 years) with 15.6%. Regarding etiopathogenesis, reactive, traumatic, and morphogenetic disorder lesions were the most prevalent, accounting for 47.5%, 25%, and 12.5%, respectively. The most frequent location was the buccal mucosa with 40%, followed by the labial mucosa with 30% of the total.
