Abstract: A dental appliance has an elongated hollow tube within the interior of which is mounted for rotation an elongated drive shaft. One end of the tube is coupled to a handle as is the drive shaft which is driven from the handle in rotation. A head joined to the other end of the tube defines an interior cavity within which a hub is mounted for rotation about an axis disposed at an angle with respect to the drive shaft. Motion is translated from the drive shaft to the hub. An opening in the head enables the hub to be accessed through the opening. Included in the hub is a barrel section for securing a variety of dental attachments thereto. A seal is created between the opening from the cavity and the hub in order to prevent fluid flow therethrough. Lubricant is introduced within the tube and the drive shaft actuates an augar or the equivalent for propelling the lubricant into the motion translator.
