Abstract
This clinical study was conducted to compare between intra-ligamentary injection of 20 mg Piroxicam and 4% Articaine after inferior alveolar nerve block injection in patients with symptomatic irreversible pulpitis of mandibular molar teeth treated in a single-visit root canal treatment as regards to their ability to control pain during access cavity preparation, instrumentation and at 6, 12, 24, 48-hrs post-operatively using Numerical Rating Scale (NRS) The study design was a double blinded randomized clinical trial as study participants and assessor didn{u2019}t know which intervention has been received.Twenty patients complaining from symptomatic irreversible pulpitis in posterior mandibular teeth were included. After thoroughly careful clinical and radiographic examination, patients were randomly assigned into two equal groups (n=10) group P, where patients received intra-ligamentary 20 mg Piroxicam, or group A, where patients received intra-ligamentary 4% Articaine. Root canal treatment was performed in single-visit using RaCe Rotary NiTi files, then Obturation was then done using modified single cone technique with resin sealer. Pain was assessed pre-operatively, during access cavity preparation, instrumentation, at 6, 12, 24 and 48-hrs post-operatively, in addition the need of supplemental anesthesia and post-operative analgesic intake were recorded. All demographic data and NRS scores obtained from patients were analyzed. Results showed similarity between the two groups regarding age, gender distribution, tooth type and pre-operative pain
