ABSTRACT:
An endodontic unit comprising an elongated ultrasonic oscillating body having a tubular conduit extending beyond one end and provided with a weighted head on the outer end and in which a socket is formed and disposed at an obtuse angle to the axis of the body by means of providing a bend in the conduit intermediately of the ends thereof subtending an obtuse angle of greater magnitude than the obtuse angle of the socket, the weight of the head being adequate to damp the vibrations imposed upon an endodontic file, when mounted in the socket, to a degree sufficient to minimize the breakage of files and also induce in the files desired vibratory and oscillating movement to effect efficient operation in endodontic performance.
