Introduction: In oral cavity there are many findings that are only detected in routine radiographic examination, among the frequent ones are dentigerous cyst, keratocyst and ameloblastoma. Objective: To carry out a comparative imaging analysis of the radiographic findings of odontogenic lesions including ameloblastoma, dentigerous cyst and keratocyst. Method: A retrospective study between 2018 and 2023 was conducted with a sample of 146 diagnostic aids of patients between the ages of 13 and 66 years attending private consultation in the city of Medellin-Colombia, divided into sociodemographic, pathological and anatomical variables. Results:The study included 98 males and 48 females, with an average age of 36 ± 5. 46% of the diagnosed cases were of dentigerous cyst confirmed by histopathology study, most of them were in the posterior mandibular region with 50% and 58% of the cases were related to third molars. Conclusions: Although the imaging characteristics are widely described in the literature, it is relevant to have clarity regarding the most predominant in the population, without neglecting the clinical and histopathological characteristics necessary to determine the definitive management.

Background: Odontogenic cysts are asymptomatic. They are diagnosed radiographically (80%) or through sporadic symptomatology (20%). There is scarce epidemiological data regarding this pathology in Colombia. Purpose: To describe the frequency of odontogenic cysts, based on the 2017 WHO classification, among patients of the National University of Colombia dental school. Methods: A cross-sectional study was carried out using clinical records of patients with diagnosis of odontogenic cysts (confirmed through histopathological analysis), whose age, sex, and cyst location (affected area) data were correctly completed. Fisher's test was used to evaluate independence between variables (p=0.05). Results: The most frequent odontogenic cysts were: dentigerous cyst (66.6%), radicular cyst (22.2%), and odontogenic keratocyst (11.2%). 77.7% were observed in men. 38.9% were diagnosed between the first and second decades of life (p=0.041) and the posterior mandibular area was the most affected (44.4%) (p=0.017). Conclusions: Dentigerous cyst were found most frequently during the second decade of life, affecting men and the posterior mandibular area. Radicular cysts did not show preference for one gender, occurred during and after the fourth decade of life and affected the anterior maxilla. Odontogenic keratocyst showed no predilection for sex or affected area and was mainly present in two different decades of life. [ABSTRACT FROM AUTHOR]
