New ultrasonic tool may reduce pain and swelling after wisdom tooth surgery

This study tested whether using an ultrasonic surgical device (piezosurgery) instead of a traditional rotary drill can reduce pain, swelling, and jaw stiffness after removing impacted wisdom teeth. Twenty-two healthy adults each had one wisdom tooth removed with the ultrasonic tool and the other with the standard drill. The researchers also measured a protein in saliva called hsCRP to track inflammation. The goal was to see if the ultrasonic method leads to a smoother recovery.
