Abstract: A new type of implant for replacement of bone or bony tissue has been developed. The implant is formed of a hydrophilic polymer having a random distribution of single size pores throughout. This hydrophilic polymer is implanted in an uncalcified, or partially calcified, state and is allowed to calcify in place, throughout its entire body, through the random pores. The hydrophilic material can be made from materials such as hydrophilic acrylates and hydrophilic methacrylates.

Abstract: Disclosed is new type of implantable material for replacement of cartilaginous or fibrous tissue. The material has controlled porosity and is biocompatible. A method for making this material is also disclosed.

Abstract: A device and procedures for endodontic therapy. An elongated flexible tubular member having a plurality of axially directed orifices formed in the distal end thereof has the proximal end thereof adapted to be connected to a source of supply of liquid. The liquid may be chemically active against necrotic tissue such as a solution of sodium hypochlorite. The distal end of the device is inserted into a root-pulp channel during a root canal procedure and liquid is delivered laterally against the walls of the channel thereby performing a mechanical scrubbing action and providing chemical action. The distal tip of the tubular member is closed off so as to prevent any liquid being expressed directly upon the root apex.

Abstract: An improved syringe is provided for root canal applications comprising a generally cylindrical or polygonal hollow barrel threaded internally at its distal end and at its proximal end, and a plunger which is substantially coextensive in length with and is adapted to slide through the cylinder. The plunger is closed face at its distal end and is externally threaded at its proximal end for threaded engagement with the internal threads at the proximal end of the cylinder. The plunger is integrally capped at its proximal end and the cap is provided with a handle for turning the plunger in order to insert it in or retract it from the cylinder. A needle is integrally attached to a hub which is provided with a central externally threaded tubular member adapted to threadedly engage with the internal threads of the distal end of the cylinder.

Abstract: A spoon excavator for administering a solution of N-monochloroglycine or other N-haloamine or like solution for effecting and facilitating dissolution of dental caries. The spoon excavator has a tubular shaft connected to a source of solution and a tip portion flattened and shaped to provide a generally spoon-like configuration for facilitating caries removal.
