Descripción de las características histopatológicas de lesiones perirradiculares en la clínica de la FOC-USTA Bogotá durante un periodo de 6 meses

Abstract

Periapical cysts and granulomas are among the most prevalent lesions. However, there are circumstances in which the clinical and radiographic patterns meet and, consequently, the need to carry out a histopathological analysis for a good diagnosis. Objective: To determine the radiographic and histopathological characteristics of the persistent periapical lesions of patients undergoing perirradicular surgeries performed in the Endodontics graduate program of the Santo Tomas University, Bogotá, during a period of 6 months. Method: Case report type study, by means of convenience sampling, patients attended by residents of the endodontics postgraduate course of the Bogotá campus, who were within the observation window, samples taken from perirradicular surgeries performed during the study, were accepted. Each of the patients was told the need to remove the lesion by means of surgery, and additionally the extracted tissue would undergo a histological analysis. Once the patient confirmed that he/she understood the procedure, the informed consent was signed. Results: The sample consisted of 10 patients, with a gender distribution of 3 men and 7 women, with ages between 27 and 67 years and a mean age of 46.7 years. There were a total of 10 periapical lesions. For each patient, clinical and radiographic evaluation and a presumptive diagnosis were made. Once the surgery was performed, the samples were sent to the laboratory for analysis, the finding of four granulomas and six cysts was reported. Conclusions: To avoid the appearance of this type of injury, it is necessary to carry out a very good endodontic treatment following the specific guidelines for each case treated.
