  • Apparatus for cleaning a root canal system
    Patent number: 8328552
    Abstract: An endodontic tool is provided to facilitate the removal of the smear layer and to enhance deep lateral cleaning of a root canal system. The tool is comprised of a sonic or ultrasonically driven activator which is made from a strong, flexible, non-metallic, and non-cutting material. The activator can be smooth. A snap-on coupler is adapted to attach the tool to a driver via a snap on action and without the use of tools. The driver will vibrate, sonically or ultrasonically, the flexible activator within a root canal of a tooth. The tool can be provided with fluid passages which allow for irrigating reagents to be delivered through the activator and into the root canal space during endodontic procedures.

  • Vibrational driver for endodontic activators
    Patent number: 7261561
    Abstract: A contra-angled driver receives an endodontic activator to induce vibrations and/or oscillations in the activator at sonic frequencies. The driver includes a quick connect/disconnect to allow for quick and simple mounting and dismounting of the activator.
