[Endosonics: a new era of endodontic therapy?].

Biomechanical instrumentation of the pulp canal is considered as an essential step in endodontic therapy. Hand instrumentation is not able to clean all of the root canal system completely, therefore endosonics has been used for cleansing and shaping the root canal space. Endosonics provides a more efficient irrigation and a stress reduction procedure. However, endosonics should not be regarded as an alternative method of debridement at present. It can be used as an adjunct for more effective root canal preparation.
