Buffered vs. Unbuffered Local Anesthesia in Mandibular Molars Diagnosed with Symptomatic Irreversible Pulpitis: A Controlled, Randomized Double-blind Study

Overview

The purpose of this study is to determine whether one type of anesthetic (numbing medicine) will work better at numbing the nerve in a tooth than using a different type of anesthetic. A second purpose is to see if the time needed to numb the nerve in a tooth is different between the two anesthetics. 
 
Potential research subjects will be pooled from patients scheduled to receive an endodontic evaluation and/or a nonsurgical root canal therapy (NSRCT) in the Graduate Endodontic clinic at Indiana University School of Dentistry.
