Brief Summary

To compare the postoperative pain in patients undergoing root canal instrumentation with two different file systems, WaveOne and ProTaper systems.

Detailed Description

Endodontic postoperative pain is experienced after the procedure of root canal. It is defined as an unpleasant sensation, of varying degree, 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 shape of the root canal. The debris produced by these instruments is potentially lesser than the manual files. Mainly because they have rotary action and they 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. WaveOne 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.

Relation between debris extrusion and postoperative care has not been established in any previous study. This study is aimed at comparing the use of ProTaper Universal and WaveOne system, for preparation of permanent human teeth during root canal procedure and their effect on postoperative pain.

Study & Design

• Study Type: INTERVENTIONAL

Primary Outcome Measures

Name	Time	Method
Post operative pain	6 hours - 72 hours	Document and compare post-operative pain after root canal treatment, after using two different motorized file systems with different mechanisms. The Visual Analog scale (VAS) would be used to assess the pain. The patients would be guided in detail about the VAS scoring system and mark pain according to the readings on VAS.
