About this study
Official title: Comparative Evaluation of Postoperative Pain After Root Canal Preparation With Rotary (Hyflex EDM) vs Reciprocating (Reciproc VDW) System in Molar Teeth: A Randomized Controlled Trial
To compare the postoperative pain in patients undergoing root canal instrumentation with two different file systems, Hyflex EDM and Reciproc VDW.
Read the detailed description
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.

| Study group | Role | What they receive |
|---|---|---|
| Hyflex Group | Active comparator | These patients underwent root canal treatment due to pain in their molar teeth. The file system used in this arm was Hyflex EDM (Coltene), a rotary file system that moves in a complete 360° rotation and prepares a root canal. Receives: Device: Hyflex EDM system |
| Recriproc Group | Active comparator | These patients underwent root canal treatment due to pain in their molar teeth. The file system used in this arm was Reciproc (VDW), a reciprocating file system that moves in 130° anticlockwise and 50° clockwise motion and prepares a root canal. Receives: Device: Reciproc VDW system |
What is being measured
The primary outcome is the main question the study is designed to answer.
Post Operative Pain
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. The scale is numbered from 1 - 10, with 1 indicating no pain and 10 indicating worst pain imaginable.
Measured: 6 hours - 72 hours
