Ultrasonics in Endodontics: A Review

The piezoelectric ultrasonic device has the potential to become routinely incorporated into almost every component of endodontic treatment, re-treatment, and apical microsurgery. It is already indispensable as a precise tool with which the most challenging clinical situations, such as finding hidden root canals and removing root canal obstructions, can be done with relative ease, predictability, and conservancy. It can be seen by the few innovative studies which take advantage of the energizing ability of ultrasound that a thorough understanding of how ultrasonic tips and files behave with irrigants and tooth structure can produce methods and conditions to truly enhance the beneficial effect of such energy in the confined root canal space
