Brief Summary

Pain is a very important factor in Endodontic treatment, Both intra- and Post-operatively. In case of symptomatic Irreversible pulpitis, a build up of inflammatory mediators makes it very difficult for the operator to reach the desired level of anesthesia in order to deliver a pain free treatment as well as to eliminate or at least reduce post-operative pain incidence and severity. therefore, a number of pre- medications was suggested with variable success rates. Therefore this trial aims at the use of a new category of anti-inflammatory medications which would be less harmful than the standard NSAIDs or steroids.

Outcome Measures

Primary Outcomes (2)

  • Success of Anesthesia

    Success of Inferior alveolar Nerve block anesthesia will be measured by recording the patient's pain severity before and after anesthesia administration as well as during endodontic procedures. each patient will record his/her pain on a "Numerical Rating Scale" (NRS), the NRS is an eleven point scale anchored at both ends by zero representing no pain and 10 representing pain as bad as it could be.

    through study completion "an average of 1 year"

  • Post-operative pain

    postoperative pain as recorded by the patient after completion of treatment in on visit. patient will receive a pain diary to record their postoperative pain incidence and severity at 6, 12, 24, 72 hours and 7 days after endodontic treatment. Each patient will record his/her pain on a "Numerical Rating Scale" (NRS), the NRS is an eleven point scale anchored at both ends by zero representing no pain and 10 representing pain as bad as it could be.

    through study completion "an average of 1 year"
