Dental treatments and methods, including treating gum disease, using peroxide gel and a viscous antibacterial agent including tetracycline to chemically debride and curettage a treatment area. Treatments and methods include non-surgically scaling and root plaining the treatment area with dental tools such as periodontal scalers and/or curettes during the active period of the chemical debridement. The working surfaces of dental tools can be sharpened for optimal root and tooth surfacing during treatment. Treatment can include instructions for co-therapy by or on behalf of treatment subjects between visits and for maintenance care.

A root canal length measuring device includes a display for displaying a control mode figure indicating an execution control mode executed among a plurality of control modes and a control unit for controlling the display to display the figure. A plurality of elements for displaying the control mode figure include a shaft portion extending in an arc shape or a fan shape and a clockwise head portion and a counterclockwise head portion indicating a first direction and a second direction as rotation directions of a cutting tool, respectively. The control unit controls the display according to the execution control mode in a root canal treatment device so that, among the plurality of elements, an entirety or a part of the shaft portion and the clockwise head portion and/or the counterclockwise head portion are displayed on the display.

An endodontic file, for manual or motor driven use by an endodontist, includes a color-coded handle, a shank, and a serrated cutting edge. The cutting edge of the endodontic file is side-cutting with pyramidal teeth and ends in a pointed tip. The endodontic file is used manually inside the root canal in an “up and down” axially aligned motion and these pyramidal teeth will provide a ripping action. A second type of endodontic file has a curved cross section and a sharpened tip. with pyramidal teeth lining the edges of curved blade section. A third type of endodontic file has a flat debriding side which tapers to a point; with a series of adjacent 3-D pyramids emerging from this surface for removing loose material or in urging already loosened material from a root canal.

A laser emitting orthodontic assembly includes a plurality of reamers that is each insertable into a root canal in a tooth. A plurality of files is provided and each of the files is insertable into a root canal in the tooth. Each of the files has a diameter that is greater than the largest diameter of the plurality of reamers thereby facilitating the files to increase the diameter of the root canal. A laser generator is provided that emits laser light outwardly therefrom. A fiber optic cable is attachable to the output of the laser generator to communicate the laser light. The fiber optic cable is insertable into the root canal to communicate the laser light onto an abscess for eliminating the abscess without conventional surgical intervention.
