Abstract
Cross-Sectional Data Analysis of the Outcome after Root Tip Resection with or without Previous Root Canal Revision or Retrograde Root Filling
Highlights
Irreversible pulpitides or infected pulpanecroses are the most common indication for endodontic treatment in conservative dentistry
Group 1 had a revision before root tip resection, and Group 2 had primary root tip resection (1a/2a with retrograde filling, 1b/2b without retrograde filling)
Apical inflammations recur in many cases, which is mostly caused by the persistence of microorganisms or their ramifications, especially in the apical third of the root [1]
Summary
Irreversible pulpitides or infected pulpanecroses are the most common indication for endodontic treatment in conservative dentistry. The goal of a revision remains unchanged, which is to completely disinfect the entire root canal system to prevent reinfections [6,7]. If this treatment remains a failure and apical inflammation persists, surgical intervention is indicated. Through surgical access via the vestibular bone lamella, the root apex in the last apical third of the root and the granulation tissue are removed. The choice of the appropriate therapy procedure varies between endodontists and surgeons, and the current data situation can shed light on this controversy
