ClinConnect Summary

This clinical trial is studying a new device called the EZ-BLOCK® that helps dentists deliver anesthesia for tooth extractions more effectively than the traditional method, known as freehand administration. The goal is to see if using this guiding device can improve the success of numbing the area around the lower jaw, especially for patients having their wisdom teeth removed. Current methods can vary in how well they work, and the EZ-BLOCK® aims to provide a more reliable and personalized approach based on each patient's unique anatomy.

To participate in the trial, you need to be at least 18 years old and have recent dental images showing your wisdom teeth. Additionally, both of your lower wisdom teeth should have similar characteristics to be eligible. If you're pregnant, allergic to anesthesia, or have certain health conditions, you may not be able to join. If you take part, you'll receive either the EZ-BLOCK® technique or the traditional method and will be monitored throughout the process, helping researchers determine which method is more effective for numbing the area before tooth removal.
