Comparison of Preoperative Analgesics on the Efficacy of Inferior Alveolar Nerve Block.

The purpose of this study is to see how preoperative oral diclofenac sodium, piroxicam, and tramadol affects inferior alveolar nerve block efficacy during root canal treatment of mandibular molars with symptomatic irreversible pulpitis. The proposed hypothesis is that the tested drug groups will improve the efficacy of inferior alveolar nerve block in comparison to the control group.
