Ultrasonics in Endodontics
Spartan EIE Ultrasonics

Recent advances in ultrasonics have improved the efficiency of several areas of Endodontics. Through the use of specially designed ultrasonic tips, calcified orifices and small canals can be explored and excavated. Post removal is facilitated by not only being able to "trough" around the post but also by ultrasonic vibration applied to the post itself.
Most significantly, ultrasonic root end preparation has dramatically reduced the need to heavily bevel root ends during periapical surgery. Research has recently showed that increased angle of bevel is associated with higher level of leakage as well as greater possibility of missing canals during resection.
A newer Ultrasonic unit has become available from Satelec. It appears to be more efficient and better suited to use with ultrasonic tips. Clinician reviews have been very favorable and it works well, especially with the new Carr Troughing Tips. (available at Endotips.com). I had a chance to try one at the ROOTS Summit II in San Diego 2002. It is a very powerful unit.
UPDATE Dec. 04
I purchased a Satelec P5 and have been impressed with its power and range. I would recommend this as a first choice.
