Evaluation of post-obturation pain after using different obturation techniques in patients undergoing root canal treatment - a randomized controlled trial

One of the important aspects of root canal therapy is to control pain after treatment. Postoperative pain is an unwanted yet unfortunately common sensation after endodontic treatment. The incidence of postoperative pain was reported to range from 3% to 58%.There is no single factor affecting pain after root canal treatment and it may be due to mechanical, chemical and/or microbial injury to the pulp or periradicular tissues. Mechanical factors, including over instrumentation or extrusion of root-filling materials, have been associated to the presence of postoperative pain.
