Mineral Trioxide Aggregate (MTA) vs Gutta-Percha for Non-Surgical Endodontic Retreatment in Teeth With Apical Lesions
Sponsor: University of Santiago de Compostela
Summary
The main objective of this study is to compare the healing rate of periapical lesions after non-surgical endodontic retreatment in teeth obturated with gutta-percha versus those obturated with mineral trioxide aggregate (MTA), with a 12-month follow-up. Secondary objectives include evaluating differences between groups in healing time, postoperative pain, and tooth discoloration.

Interventions
Mineral trioxide aggregate (MTA) group
Root canal obturation performed using mineral trioxide aggregate (MTA) following non-surgical endodontic retreatment. After removal of the previous root canal filling, chemomechanical preparation and irrigation of the root canal system are performed. Calcium hydroxide is used as intracanal medication between visits prior to final obturation with MTA
Gutta-percha group
Root canal obturation performed using gutta-percha and a resin-based sealer following non-surgical endodontic retreatment. After removal of the previous root canal filling, chemomechanical preparation and irrigation of the root canal system are performed. Calcium hydroxide is used as intracanal medication between visits prior to final obturation with gutta-percha using the continuous wave technique.
