Objectives
Narrative objectives1
This multicenter randomized clinical trial (RCT) was conducted to examine the early postoperative complications in mandibular horizontal third molars and to compare the effects of the two flap designs. Achieving this goal will most likely suggest the usefulness of mEF with resultant reduced postoperative complications for patients and enhanced quality of life.
