The aim of the study is to evaluate the effect of preoperative administration of acetaminophen- codeine -caffeine combination on the success of the inferior alveolar nerve block versus bacetaminophen alone or placebo in patients with symptomatic irreversible pulpitis.
Full Title of Study: “Effect of Preoperative Acetaminophen-Codeine-Caffeine Combination on Inferior Alveolar Nerve Block Success in Patients With Symptomatic Irreversible Pulpitis: Randomized Double-blind Controlled Trial”
- Study Type: Interventional
- Study Design
- Allocation: Randomized
- Intervention Model: Parallel Assignment
- Primary Purpose: Prevention
- Masking: Double (Participant, Investigator)
- Study Primary Completion Date: May 2021
After ensuring eligibility, patients will be given premedication 1hr before treatment,which will be done in single visit. After 1 hour, Pretreatment pain "pain after administration of analgesic or placebo" will be recorded using 0-10 numerical rating scale (NRS) . Local anesthesia will, then, be done through inferior alveolar nerve block using 1.8 ml Mepivacaine. The teeth will be isolated using rubber dam and access cavity will be prepared using #2 high-speed round bur. The patients will be asked to rate their pain on the NRS. The degree of pain during access preparation and/or instrumentation will be recorded. Success will be defined as no pain or mild pain during endodontic access preparation and/or instrumentation. Any pain more than no pain or mild pain will considered a failure. The patients will be instructed to return after 2 days to complete the treatment procedures.
- Drug: Acetaminophen and codeine and caffeine
- The patient will receive pretreatment oral single dose of Combination of 1000mg acetaminophen- 16mg codeine- 60mg caffeine 1 hour before treatment.
- Drug: Acetaminophen
- The patient will receive pretreatment oral single dose of 1000mg acetaminophen alone 1 hour before treatment.
- Drug: Placebo
- The patient will receive placebo (starch) 1hour before treatment.
Arms, Groups and Cohorts

Clinical Trial Outcome Measures
- Success of mandibular inferior alveolar nerve block anesthesia during access and instrumentation.
- Time Frame: During the treatment
- Will be recorded by 11 point NRS consisting of numbers from 0 through 10. 0: reading represents “no pain” 1-3 : readings represent “mild pain” 4-6 : readings represent “moderate pain” 7-10 : readings represent “severe pain” 0: reading represents “no pain” 1-3 : readings represent “mild pain” 4-6 : readings represent “moderate pain” 7-10 : readings represent “severe pain”
