Ultrasonic tips in periradicular surgery

ABSTRACT

Technological advances have increased the rate of success of dental procedures. In periradicular surgery, the use of ultrasonic tips ensures high-quality root-end cavity preparations, enables the performance of a 90-degree apicoectomy, and removes larger amounts of contaminated material. The authors reviewed in vitro and in vivo studies in the literature and evaluated root-end cavities prepared with burs or ultrasonic tips using scanning electron microscopy.
