There is provided a dental tool for use with a reciprocating drive means and a sleeve member operatively connected to the drive means for reciprocating motion and designed to retain a dental tool, the dental tool comprising a shank portion designed to be retained for reciprocating movement by the sleeve member of the handpiece, and a dental blade, preferably with an abrasive surface, secured to one end of the shank; in one embodiment, the dental tool is preferably hollow and further comprises an axially extending channel, preferably extending along the full length of the shank and a plenum extending within the dental blade, and outlet perforations from the plenum extending through the blade, and in a second embodiment there is further provided means secured to the shank portion for spplying pressure within the channel to force any fluid material within the channel and plenum out through the outlet perforations through the blade. Finally, there is provided means for dispensing fluid material, e.g., a cleaning paste, into the shank channel comprising syringe means having a reservoir section and pressure applying means for injecting fluid within the reservoir into the shank of the tool. Preferably, the tool further comprises rotation restraining means, such as an elastically deformable stop member, for providing limited resistance to rotation of the dental tool while it is being subjected to reciprocating motion and the application of axial force during dental therapy.
