Ultrasonic instruments have a delicate tip that vibrates at high frequencies and provides copious irrigation.  Ultrasonics are essential in calcified teeth, retreatment cases, post removal, and in performing precision microsurgery.

Ultrasonics in endodontics has enhanced the quality of treatment and represents an important adjunct in the treatment of difficult cases. Sonic activation devices are designed to vigorously energize intracanal antimicrobial irrigants.  They are also a significant advancement in disinfection and improve debridement and the disruption of the smear layer and biofilm.  One can expect increased post-treatment comfort and more predictable outcomes.
