Randomized Controlled Trial Comparative StudyBuffered lidocaine for incision and drainage: a prospective, randomized double-blind study.
Buffered local anesthetics have not been studied for incision and drainage procedures in dentistry. The purpose of this prospective, randomized, double-blind study was to compare the pain of infiltration and pain of an incision and drainage procedure by using a buffered versus a nonbuffered 2% lidocaine with 1:100,000 epinephrine solution in symptomatic patients with a diagnosis of pulpal necrosis and associated acute swelling. ⋯ The addition of a sodium bicarbonate buffer to 2% lidocaine with 1:100,000 epinephrine did not result in significantly decreased pain of infiltrations or significantly decreased pain of the incision and drainage procedure when compared with 2% lidocaine with 1:100,000 epinephrine in symptomatic patients with a diagnosis of pulpal necrosis and associated acute swelling.

Randomized Controlled Trial Comparative StudyA new method of topical anesthesia by using anesthetic solution in a patch.
We investigated the effects of topical anesthesia of the oral mucosa by using an adhesive patch instilled with 2% lidocaine hydrochloride solution. ⋯ Topical mucosal anesthesia with an adhesive patch containing 2% lidocaine hydrochloride solution is simple and may be more effective than conventional methods.
