Abstract
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.
