Buffered vs. Unbuffered Local Anesthesia in Mandibular Molars Diagnosed With Symptomatic Irreversible Pulpitis

Summary

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.
