OBJECTIVE: Randomized clinical prospective study to evaluate the application of MTA and IRM as retrograde sealers in surgical endodontics. STUDY DESIGN:One hundred single-rooted teeth were surgically treated. After randomization, MTA or IRM was used as a retrosealer. Radiographs were taken 1 week, 3 months, and 1 year postoperatively. Assessment was performed by 2 independent assessors 1 year after surgery. Both treatment groups were homogeneous in their composition, and clinical features and radiographic findings were classified according to Rud's classification. RESULTS:Complete healing was observed in 64% of the MTA-treated teeth vs 50% of the IRM-treated teeth. Incomplete healing was seen in 28% (MTA) vs 36% (IRM), and unsatisfactory in 6% (MTA) vs 14% (IRM). Only 1 failure was seen (MTA). No statistically significant differences were found between the 2 retrofilling materials. CONCLUSION: As root-end filling materials in this clinical prospective randomized design on single rooted teeth, MTA and IRM had the same clinical effectiveness.
