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).

•Clinical significance:   

• There is no  significant difference in the 4-year success rates of MTA and Super EBA as root-end filling materials in endodontic microsurgery
