A vibratory endodontic device is described for mechanical preparation of dental radicular canals, i.e., root canals, prior to their obturation. The device includes a housing, a vibratory drive means supported within the housing to minimize the transfer of vibration to the housing, an endodontic file connected to the drive means for vibratory movement and stop means operatively connected to the housing and substantially isolated from the mechanical vibrations created by the vibratory drive means. Additionally, fluid transport means are provided for maintaining a controllable or a continuous flow of irrigation fluid along the endodontic file. Various assemblies for retaining the endodontic files and the stop means at the operative end of the vibrating device are also described. |
