Comparison of Postoperative Pain After Root Canal Treatment With Rotary vs Reciprocating Systems

Overview

To compare the postoperative pain in patients undergoing root canal instrumentation with two different file systems, Hyflex EDM and Reciproc VDW.

Endodontic postoperative pain is experienced after the procedure of the root canal. It is defined as an unpleasant sensation, of varying degrees, experienced by the patients. Depending upon the individual and other variable, the range of postoperative pain lies between 3% to 58%. Endodontic postoperative pain could occur due to various factors that can be microbial, injured pulp, chemical, or mechanical. Factors that influence pain following a root canal include the presence of preoperative pain, apical debris extrusion, intracanal interappointment dressing extrusion, presence of periapical pathosis, hyper occlusion, and irrigant extrusion. Although apically extruded debris can be reduced through various means, it cannot be completely avoided. Thus, increasing the incidence of postoperative pain in patients. The debris produced during apical extrusion contains necrotic tissue, dental chips, microbes, pulp tissue, and canal irrigants. The infected debris may disturb the balance between the microbes and the immune system, leading to acute exacerbation. Manual steel K files tend to produce more debris, causing a high risk of postoperative discomfort. Nickel-titanium rotary instruments powered by the engine have various advantages including; time-saving, preservation of root canal anatomy, and homogeneous preparation of the root canal shape. The debris produced by these instruments is potentially lesser than the manual files. Mainly because they have rotary action and excavate the debris with the help of their flutes. Repeated irrigation along with the action of an engine-driven instrument, has the potential to decrease postoperative pain. Reciproc VDW reciprocating file instruments have potential advantages including reduced fatigue, resistance to fracture, less debris extrusion, good shaping ability, no cross-contamination (single use), and reduced cost. No previous study has established a relationship between debris extrusion and postoperative care. This study aims to compare the use of the Hyflex EDM and Reciproc VDW systems for preparing permanent human teeth during root canal procedures and their effect on postoperative pain.
