Comparison of Post-Operative Pain Occurrence After Single Visit Root Canal Treatment with Two NiTi Rotary Files - a Randomized Clinical Trial

Overview

The goal of this clinical trial is to compare the post-operative pain occurrence after single visit root canal treatment using Two NiTi Rotary Files. The main question it aims to answer is: • Does an instrument design and instrumentation technique could affect postoperative pain incidence and intensity? Researchers will use ProTaper Universal rotary system or M-Pro rotary system for root canal preparation and compared postoperative pain intensity. Participants will receive single visit endodontic treatment using either ProTaper or MPro systems for root canal preparation. Participants will record Pain intensity at 24 hours and 7 days post-operative. Analgesics will be prescribed for the patients in need.

Detailed description

The main cause of patient fear is expecting pain during root canal treatment. It is considered a major concern for dentists as well. During root canal preparation, periapical extrusion of pulpal tissue remnants, microorganisms or dentin chips may be one of the causes of postoperative pain. Depending on the fact that, instrument design and instrumentation techniques have an impact on the amount of extruded debris apically, many studies proved the ability of some rotary systems to reduce debris extrusion, permitting to achieve less pain sensation.

Therefore, the present clinical study aims to compare the postoperative pain intensity in molars with symptomatic irreversible pulpitis after single endodontic treatment visit using a full-sequence rotary Ni-Ti system either ProTaper or MPro systems Eighty patients with symptomatic irreversible pulpitis in mandibular first molars will be assigned into two groups. In group A (n=40): root canal preparation will be performed in single visit using ProTaper Universal system and in group B (n=40): root canal preparation will be performed in single visit using M-Pro rotary system. Pain intensity will be recorded by the patient using Numerical Rating Scale (NRS) at 24 hours and 7 days postoperative. Analgesics will be prescribed for the patients in case of need.

Interventions

  • Procedure single visit root canal treatment using ProTaper Universal rotary system
    single visit endodontic treatment will be performed using ProTaper Universal rotary system for root canal preparation.
  • Procedure single visit root canal treatment using M-Pro rotary system

Primary outcome measures

  • Record the intensity of postoperative pain after root canal treatment with ProTaper Universal and M-Pro endodontic rotary files. [Time frame: 7 days]

Eligibility criteria
