Study Summary

This trial is testing whether using a twin block injection to numb the 'jaw-clencher' muscles can reduce pain and the need for opioids following wisdom tooth removal.

Who is the study for?

This trial is for healthy adults over 18 needing at least one lower wisdom tooth removed, who can use a smart device with internet. They shouldn't have jaw pain or limited motion history, be pregnant, prisoners, children, or intellectually disabled. Allergies to local anesthetics or common pain relievers like Tylenol and Advil are disqualifiers.Check my eligibility

What is being tested?

The study tests the Twin Block dental anesthetic injection versus a placebo in managing post-wisdom tooth removal pain. It aims to see if this technique reduces both the intensity of jaw-clencher muscle pain and the need for opioid medication after surgery.See study design

What are the potential side effects?

While not explicitly stated in the provided information, typical side effects from dental anesthesia may include temporary numbness or tingling sensations, minor bruising where injected, slight bleeding around injection sites and rarely allergic reactions.

Active Control

Placebo Group

Group I: Twin Block with Local AnestheticActive Control1 Intervention

Following lower third molar extraction under intravenous sedation, the patient randomized to this arm with receive the Twin block local anesthetic nerve block using the standard dental local anesthetic, i.e,. 2% lidocaine with 1:100,000 epinephrine, on the day after extraction, if the patient has pain greater than or equal to 5 on 10 in their jaw-closer muscles (Numerical Pain rating scale).

Group II: Twin Block with sterile normal salinePlacebo Group1 Intervention

Following lower third molar extraction under intravenous sedation, the patient randomized to this arm with receive the Twin block using sterile normal saline, on the day after extraction, if the patient has pain greater than or equal to 5 on 10 in their jaw-closer muscles (Numerical Pain rating scale).
