Postoperative Pain and Bacterial Reduction in Oval Canals After Instrumentation With Different Noval Rotary Files Systems

Effect of Different Rotary Files Systems on Post-operative Pain and Bacterial Reduction in Lower Single Canal Posterior Teeth With Necrotic Pulp: Prospective Double Blinded Clinical Trial

• Status: Active Not Recruiting
• Phase: N/A
• Study type: Interventional
• Enrollment: 120 (estimated)

• Healthy volunteers: Accepted

Summary

Postoperative pain after endodontic treatment can affect a patient's quality of life. It is reported that debris extrusion after the instrumentation technique can influence postoperative pain. As a result, the aim of this clinical trial is to compare the recent rotary systems (TruNatomy, ProTaper Ultimate, Hyflex EDM and XP- rise rotary files systems) in terms of apical extrusion defined by post-operative pain and their role in reducing the bacterial count inside the canal

Detailed description

One hundred and twenty lower premolar teeth will be included in the study(n=120). Teeth will be randomly assigned to one of the 4 groups(n=30). Preoprative pain will be recorded before root canal treatment. Postoperative pain will be recorded using visual analogue scale (VAS) at 6 hours,12 hours, 1day, 2 days, 3 days, 4 dayse and five days after the root canal treatment. Bacterial count before and after instrumentation will be determined using culturing methods to determine the bacterial count reduction.
