Randomized clinical trial of root‐end resection followed by root‐end filling with mineral trioxide aggregate or smoothing of the orthograde gutta‐percha root filling – 1‐year follow‐up

Abstract

The results from this RCT emphasize the importance of placing a root-end filling after root-end resection. Teeth treated with MTA had significantly better healing (96%) than teeth treated by smoothing of the orthograde GP root filling only (52%).
