Each year, over 3.5 million, mostly, healthy young adults, have their third molar teeth ('wisdom teeth') removed under sedation and are often given opioid prescriptions for managing their pain. Wisdom molar removal is one of the most common reasons for opioid prescriptions to be given to adolescents. There is a national thrust to reduce both the dose and the duration of such opioid prescriptions because even short-term opioid exposures increase risk for narcotic addiction and misuse. Non-opioid options to manage pain will still allow for sufficient pain control without risking addiction, and hence, a fundamental component of our response to combat the current national opioid crisis.~The investigators are going to study a promising option- the Temporo-masseteric Nerve Block (TMNB) dental anesthetic injection (This was called the Twin Block earlier). The TMNB involves injecting the standard dental numbing medication in a way that 'numbs' the 'jaw-clencher' muscles on the side of the face. The investigators found that the TMNB relieved jaw pain stemming from these muscles, in a quick and sustained manner, even in patients whose pain following wisdom tooth removal primarily came from 'taut' and tender jaw-clencher muscles.~In this pilot study, the investigators will deliver the Temporo-masseteric Nerve Block (TMNB) injection to 20 individuals (study participants) who undergo extraction of at least 1 lower wisdom molar dental extraction under intravenous sedation, on the side/s of lower molar removal at the end of the procedure. The participant's pain experience, medications taken for pain, as well as any adverse effects from either pain medications or the TMNB injection will be queried for a period of 1 week following the procedure (remotely). On Day 8 (one week after the procedure), the participants will return for a follow-up visit. The participants' pain experience will be compared with historical controls. This study can support a simple, safe and inexpensive means to reduce pain after a common procedure and will provide proof-of-concept for the potential non-opioid analgesic role of TMNB injection following wisdom molar removal.~The participant will be advised to take a combination of ibuprofen and acetaminophen (600 mg ibuprofen and 325 mg acetaminophen) every 4-6 hours for pain, unless it is mild, for which OTC strength analgesics would prove adequate (ibuprofen or acetaminophen). 5/300 mg hydrocodone with acetaminophen will be utilized for pain management if the patient's pain does not respond to 600 mg ibuprofen and 325 mg acetaminophen, even an hour after medication.~The key outcomes collected will include peak-pain by 4 hours post-procedure (measured using numerical pain rating scale score NRS, from 0-10, with 0 corresponding to no pain, 1-3 corresponding to mild, 4-6 to moderate and 7-10 to severe pain), passive mouth opening, masticatory muscle pain to palpation (masseter and temporalis muscles), total dosage of pain medication/s consumed. Adverse effects to pain medication consumption (nausea/ drowsiness/ gastritis etc) or to the TMNB injection will also be recorded. Daily pain experience will be recorded each of the 7 days post-operatively either as a survey emailed to the participant or queried over the phone by research personnel.~A week after the procedure, the participant will present for a post-operative evaluation. The extraction/s site/s will be evaluated for any infection/delayed healing.
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.
