ABSTRACT


Aim: The Study Was Designed To Compare The Anesthetic Efficacy Of 2% Mepivacaine With 1:100000 Epinephrine To That Of 4% Articaine With 1:100000 Epinephrine In Inferior Alveolar Nerve Block Injection For Mandibular Molars With Symptomatic Irreversible Pulpitis During Access Cavity Preparation And Root Canal Instrumentation. Methods: Sixty-six Patients With Symptomatic Irreversible Pulpitis In Their Mandibular Molars Were Randomly Allocated To Two Groups Receiving IANB Injection Of Either 2% Mepivacaine With 1:100 000 Epinephrine Or 4% Articaine With 1:100 000 Epinephrine. Root Canal Treatment Was Started At 15-minutes Post Injection In Presence Of Profound Lip Numbness And Completed In A Single Visit. Patients Were Asked To Rate Their Preoperative Pain, Pain During Access Cavity Preparation And Root Canal Instrumentation On A Numerical Rating Scale (NRS).

Results: Anesthetic Success Of The Mepivacaine Group Was (42.4%) While That Of Articaine Was (39.4%). The Difference Between The Two Groups Was Not Statistically Significant (p= 0.802). Conclusion: Anesthetic Efficacy Of 2% Mepivacaine Was Similar To That Of 4% Articaine In Inferior Alveolar Nerve Blocks For Anesthetizing Mandibular Molars With Symptomatic Irreversible Pulpitis.
