A device, method and composition of matter for use in mobilizing a medicament into the dentinal wall of a tooth comprising depositing a charged substance within a cavity of a tooth and subjecting the substance to an electric charge.

Method and apparatus for disinfecting and / or sterilizing a root canal system by targeting the water content of disease and debris in the canals. The laser technique of employs a frequency of the wavelength emissions between about 930 to about 1065 nanometers with an optimum of 980 nm. This range of wavelengths targets the water content of tissue cells and pathogens as well as any residual organic debris in water within the root canal system after its preparation while being poorly absorbed by the surrounding dentin. The selection of the optimum wavelength produces significant effects generating and advancing treatment to the targeted aqueous environments. This is due to the rapid energy absorption by the water and the subsequent creation of gas bubbles, liberation of heat and subsequent propulsion of waves of heat and gas that impact along the canal walls and ramifications resulting in an enhanced bacterial kill and cleaning of the canal walls and ramifications. No dyes or other additives are necessary to enhance the effectiveness of the laser kill of bacteria, etc.

A dental implant includes a spiral thread for threaded engagement with a passageway formed in bone or tooth to mechanically secure the implant. A hollow stem extends upwardly to provide a passageway to a plurality of outlets at the lower end to fill a mold from the bottom up to develop an abutment ultimately supporting a crown, bridgework, or other prosthetic. The stem includes an end for engagement by a conventional dental hand piece to rotatably insert the implant. The base of the stem may include a hexagonal nut or a double disc for engagement by a dental ratchet for final seating of the implant. The post of the implant may include one or more longitudinally aligned tips that can be cut off to conform the length of the post with the depth of bone or tooth into which it will become inserted. The stem may include one or more longitudinally aligned segments that may be severed to conform the length of the stem with the height of the crown, bridgework or prosthetic. In a variant implant, the post includes a further passageway extending from the passageway in the stem to permit injection of bonding material into the further passageway for discharge through outlets of the further passageway into annular grooves formed in the one about the cavity into which the post is inserted.

An apparatus agitates fluid in a root canal of a living patient during cleaning of the root canal. The apparatus includes a tapered tip member having a proximate end and a distal end for insertion into said root canal. The tip member is vibrated or rotated by a driving device for the tapered tip member, which is connected at a proximate end for connection to the driving device. The tip member is made of an elastomeric, non-cutting material having a smooth surface or a textured surface of non-cutting elastomeric material. Optionally, the tip member may include abrasive particles impregnated therein, or coated thereon.

An endodontic probe is used to perform disinfection procedures on target tissues within root canal passages and tubules. The endodontic probe can include an electromagnetic radiation emitting fiber optic tip having a distal end and a radiation emitting region disposed proximally of the distal end. According to one aspect, the endodontic probe can include a porous structure that encompasses a region of the fiber optic tip excluding the radiation emitting region and that is loaded with biologically-active particles, cleaning particles, biologically-active agents, or cleaning agents for delivery from the porous structure onto the target tissues. Another aspect can include provision of the endodontic probe with an adjustable channel-depth indicator, which encompasses a region of the fiber optic tip besides the radiation emitting region and which is movable in proximal and distal directions along a surface of the fiber optic tip to facilitate the provision of depth-of-insertion information to users of the endodontic probe.
