Study Details

Brief summary:

This is a pilot study evaluating the ability of the Temporo-masseteric Nerve Block local anesthetic injection (this was called the Twin Block earlier) to reduce pain experienced by individuals undergoing removal of lower third molar(s) under intravenous sedation. Study participants will be queried for pain experience and pain medications taken during the first post-operative week and will present for a follow-up visit on Day 8.

Interventions and Outcome Measures

Arms

experimental: Temporo-masseteric Nerve Block (TMNB) Injection with Local Anesthetic

Following lower third molar extraction under intravenous sedation, the patient will receive the TMNB local anesthetic nerve block using the standard dental local anesthetic, i.e,. 2% lidocaine with 1:100,000 epinephrine, on the side/s of lower wisdom molar extraction/s
