Introduction: In this paper we describe the endodontic treatment of teeth with extensive periapical lesions through case reports. Objective: Analyze the effectiveness of change the intracanal medication with calcium hydroxide, reducing or eliminating the surgical procedures and still observe, by follow up, the periapical repair. Results: After clinical and radiographic examination and found the need for endodontic treatment, was performed the coronal opening, irrigation with sodium hypochlorite 1% and biomechanical preparation with manual endodontic files. The EDTA 17% was used for 3 minutes with manual shaking before application of the medication in all the sessions as well as all sessions before the final filling. Thus, the medication with calcium hydroxide and propylene glycol was inserted in the root canal and replaced whenever the medication had been partly resorbed. After the beginning of periapical repair, the filling of the root canals was performed by the technique of horizontal and vertical condensation and radiographic controls were performed according to the availability of the patients. Conclusion: In these case reports, the renovation of calcium hydroxide as root canal dressing showed efficient in the treatment of extensive chronic periapical lesions, repairing the bone and periodontal tissues and eliminated the need for surgical intervention.
