2026年7月29日 更新者：Ameena Khaled Omar Bagunaid、Cairo University
Effect of Diclofenac Potassium Premedication Dose on Anesthetic Success and Post-operative Pain in Mandibular Molars With Symptomatic Irreversible Pulpitis: A Randomized Controlled Trial
The aim of this study is to assess the effect of different doses of diclofenac potassium premedication (100mg vs 50mg) on anesthetic success of 4% articaine buccal infiltration and post-operative pain as compared to placebo in mandibular molars with symptomatic irreversible pulpitis.

详细说明
Patients with moderate-to-severe preoperative pain are selected.
Patients receive either a single-dose of diclofenac potassium (100mg), diclofenac potassium (50mg) alone or a placebo tablet as a control.
All patients will receive the assigned premedication one hour before single-visit root canal treatment.
Anesthetic success of articaine buccal infiltration will be assessed during access and instrumentation.
Postoperative endodontic pain is measured at the following time points: 6,12,24,48,72h and 7 days after treatment.
