Endodontic treatment of large periapical lesions: An alternative to surgery

Introduction: Non-surgical treatment with calcium hydroxide offers a high success rate in the healing of large periapical lesions. Case Series: We present the healing of large periapical lesions with conservative, non-surgical treatment in three young patients presenting large periapical lesions and diagnosed with chronic periapical periodontitis. Non-surgical endodontic treatment was carried out involving canal preparation, irrigation with 2.5% sodium hypochlorite, filling of the canal with 75% calcium hydroxide and 25% Kri-1 iodoform paste mixed with sterile saline solution, and sealing of the cavity with composite. The filling was replaced several times, after which endodontic treatment was finally carried out. Complete apical healing was observed in all cases. Conclusion: Non-surgical treatment as a first option allows us to avoid the trauma of surgery in young individuals.
