Fluid controllable laser endodontic cleaning and disinfecting system
View Patent ↗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.

9. The endodontic probe as set forth in claim 8 , wherein the treating of a surface by the diode laser comprises heating or ablating the surface by the diode laser.
10. The endodontic probe as set forth in claim 1 , wherein the endodontic probe comprises a capability for outputting, from the radiation emitting region, one or more of a first radiation and a second radiation.

15. The endodontic probe as set forth in claim 1 , the endodontic probe being constructed to emit a first radiation that is highly absorbed by a biologically compatible liquid within a canal and, simultaneously or substantially simultaneously, to emit a second radiation that is not highly absorbed by the liquid.
