First seen Feb 13, 2026 · Last updated Jun 19, 2026 · Updated 19 times
Summary
This study tests whether applying cold (cryotherapy) to the gums right after a numbing shot can make root canal treatment less painful. About 100 adults with an infected lower premolar tooth will be randomly assigned to receive standard numbing methods with or without the cold treatment. The goal is to see if the cold helps the numbing work better and reduces pain during the procedure.
