ULTRASONIC ENDODONTIC TIP HAVING A LOW-MODULUS OF ELASTICITY

摘要

An ultrasonic endodontic tip is provided having an elastic modulus of less than 8 Msi. The low-modulus of the material provides the ultrasonic endodontic tip the ability to navigate a curved tooth canal during a root canal procedure and controllably remove the dentine around canal without excessively enlarging the canal. The tip can include an abrasive on at least a portion of the working surface of the tip.
