Background: Clinical epidemiological studies do not allow us to know the status of pulp and periapical disease of endodontic origin, information that can be obtained analyzing panoramic radiographs, so as to provide prevention and counseling services in oral health. Objective: To determine the frequency and characteristics of endodontic findings in digital panoramic radiographs. Methods: We analyzed 1,500 digital panoramic radiographs of patients over 18. The following information was recorded: number of teeth in the mouth, number of teeth with endodontic treatment and condition, periapical radiolucent area, fracture, resorption, broken instruments, perforations, pulp stones and hypercementosis. Results: 48% of the radiographs showed at least one endodontic finding. 39.5% were endodontic treatments in a total of 1,594 teeth, of which 52.7% were underfilled, 44.9% were in good condition and 2.5% were overfilled. 69% of the filled teeth were in the upper jaw. 275 (18.3%) radiographs presented a periapical radiolucent area. 4.4% of the radiographs showed at least one tooth with resorption. No differences between men and women were detected for any of the findings. Endodontic treatment and the presence of a periapical radiolucent area increase significantly with age. Conclusion: Pulp and periapical disease has a high prevalence in the population studied and requires better prevention mechanisms. Inadequate filling of the canals is a variable to consider to avoid apical lesions, and to improve the prognosis of the tooth.
