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

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

Key information

About this study

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.

Primary outcomes

  1. Postoperative pain

    Time frame: at 6hours,12 hours, 24 hours, 2 days, 3 days, 4 days and five days after the root canal treatment

    Postoperative pain will be recorded using Visual Analogue Scale (VAS) at 6hours,12 hours, 24 hours, 2 days, 3 days, 4 days and five days after the root canal treatment Visual Analogue Scale (VAS) ranges from 0-10, the lower number the better outcome.

    0= no pain 1-3= mild pain 4-6= moderate pain 7-10= sever pain

  2. Bacterial count reduction

    Time frame: Sample will be collected before and directly after canal prepeartion

    Bacterial count sample will be collected before and after canal prepeartion
