The Effect of Buccal Infiltration Administration of Clonidine on the Success Rate of Inferior Alveolar Nerve Block

Articaine/epinephrine and lidocaine/epinephrine are the most common routine local anesthetic agents currently used in dentistry. However, their anesthetic efficacy and pain control in patients with symptomatic irreversible pulpitis via inferior alveolar nerve block is very low. The aim of this study is to investigate the efficacy of clonidine versus articaine/epinpephrine as a local anesthetic agent for a buccal infiltration after IANB administration with lidocaine for (1) successful IANB, (2) hemodynamic stability, and (3) reducing dental anxiety for endodontic treatment in mandibular molars diagnosed with symptomatic irreversible pulpitis.
