Study summary

Objective: The aim of this study is to evaluate premedication with ketorolac infiltration on post endodontic pain in patients with symptomatic irreversible pulpitis.

Design: Randomized double blind clinical trial

Setting and conduct: Sixty adult volunteers with including criteria will be divided into two groups (n=30) based on random table. All patients will receive standard inferior alveolar nerve block of 2% lidocaine with 1:800000 epinephrine and supplemental buccal infiltration of 0.9 mL 2% lidocaine with 1:800000 epinephrine. After five minutes one group will receive supplemental buccal infiltration of 30 mg/mL of Ketorolac Tromethamine and the control group will receive buccal infiltration of normal saline. Endodontic access preparation will initiate after 15 minutes of initial IANB with two negative responses to the electric pulp test. The pain level will be recorded immediately and at the 2,4,6 and 24 hours following the treatment using Heft- Parker Visual Analog Scale (HP- VAS). Data will be evaluated using Repeated measured test (if possible) and otherwise non-parametric tests such as rival Friedman and X2 test. Participants including major eligibility criteria: all patients age ranged 18-65 with symptomatic irreversible pulpitis (HP VAS ≥54) and without pain on percussion on a mandibular molar tooth who need root canal treatment and are without systemic diseases; nonsmoking; non pregnant, non breast feeding without any medicine consumption or analgesic and sedation

Intervention: Ketorolac infiltration

Main outcome measures: Pain level at immediately after the treatment, 2, 4, 6 and 24 hours following the root canal treatment using HP VAS.

Endodontic access preparation will initiate after 15 minutes of initial IANB with two negative responses to the electric pulp test. Endodontic treatment of all the patients will be performed in a single visit, using crown down method and with rotary instrumentation till master apical file size# 30.06. The pain level will be recorded immediately and at the 2,4,6 and 24 hours following the treatment using Heft- Parker Visual Analog Scale (HP- VAS).

Study arms

  • Active comparator
    Buccal infiltration of Ketorolac

    All patients will receive standard inferior alveolar nerve block of 2% lidocaine with 1:800000 epinephrine and supplemental buccal infiltration of 0.9 mL 2% lidocaine with 1:800000 epinephrine. After five minutes, case group will receive a supplemental buccal infiltration of 30 mg/mL of Ketorolac tromethamine (Alborz-Darou Co. Qazvin, Iran).

    Drug: Ketorolac Tromethamine

  • Placebo comparator
    Buccal infiltration of Normal saline

    All patients will receive standard inferior alveolar nerve block of 2% lidocaine with 1:800000 epinephrine and supplemental buccal infiltration of 0.9 mL 2% lidocaine with 1:800000 epinephrine. After five minutes, the control group will receive normal saline as placebo.

    Drug: Placebo
