Purpose: to evaluate the long-term clinical outcomes of endodontic microsurgery when MTA and Super EBA are used as the root-end filling material and to compare the clinical outcome of endodontic microsurgery at 1-year and 4-year follow-ups.
•260 Teeth were included in this randomized controlled trial and randomly assiegnd either MTA or Super EBA groups ( 130 teeth each group ) •Inclusion criteria : all root-filled cases with symptomatic or asymptomatic apical periodontitis were included.
•Exclusion criteria : teeth with a through-and-through lesion and/or a lesion of combined periodontal endodontic origin, class II mobility , horizontal and vertical root fractures, and perforations
•The patients were recalled periodically at 3, 6, and 12 months and every year after the treatment up to 4 years
•Radiographic healing was classified as complete healing, incomplete healing (scar tissue), uncertain healing, or unsatisfactory healing
Most highlighted Results:
-Among the 260 teeth included in this randomized controlled trial, 182 were examined at the 4-year follow-up
-In the MTA group, 83 of 130 cases were recalled, and the success rate was 91.6% (76/83 cases).
-In the Super EBA group, 99 of 130 cases were recalled, and the success rate was 89.9% (89/99 cases)
-Statistical analysis of the success rate at 4 years after endodontic microsurgery did not show any significant difference between the 2 materials (P = .8).
• There is no significant difference in the 4-year success rates of MTA and Super EBA as root-end filling materials in endodontic microsurgery
