A method treating a root canal in a tooth by introducing into the pulp chamber of a tooth and pulsing a laser light into the fluid reservoir so as to disintegrate pulp within the root canal without generation of any significant heat in said liquid fluid so as to avoid elevating the temperature of any of the dentin, tooth, or other adjacent tissue more than about 5° C.

Dental and medical treatments and methods, including treating gum disease, using peroxide gel and a viscous antimicrobial including a topical antibacterial agent, a topical antiviral agent, a topical antibiotic, a topical antifungal agent, a topical antiseptic agent, or a topical anti-intermicrobial agent 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 and medical 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.

The disclosed invention relates to a system and method for treatment of root canals, e.g., to clean, decontaminate and remove the smear layer. The system can include a laser source; a hand piece; and a device for directing radiation emitted by the laser source to a liquid creating pressure that result in irrigation. In some cases, the handpiece can include an optical element adapted to modulate a laser beam such that it is dispersive or focused.

The present invention describes an endodontic high-performance polymer micro-capillary cannula for use with a dental tool having an ultrasonic/sonic energy generator, and providing concomitantly irrigation, activation of the irrigation liquid and evacuation of the root canal content. The micro-capillary cannula provides continuous delivery of an irrigant from the ultrasonic or sonic handpiece while vibrating inside canal, allowing the activation of the irrigant. Energy generated by an ultrasonic or sonic generator is translated into movement of the cannula to provide optimum cleaning to the root canal. Simultaneously, negative pressure is formed at the tip end of the cannula by a tubing connection at the proximal end of the cannula, which is connected to the suction dental unit. The evacuation at the end of the cannula helps irrigant movement from the coronal part of the canal to the apical part, while avoids apical extrusion of the irrigant.

This invention is about a root canal activator and the activation method. It belongs to technical field of root canal treatment equipment. The eccentric wheel is connected with a oscillatory needle, which is composed of a needle head, a spherical joint and a connecting rod. The connecting rod is connected through a spherical joint to the ball-shaped slot of the eccentric wheel and therefore, a spherical pair is formulated to allow for a degree of freedom. There is a head cover made of soft rubber mounted at the top end of the outer shell. The oscillatory needle is mounted inside the soft rubber cover through a cylindrical joint, which has formulated a cylindrical pair and allows for five degrees of freedom in total.

A method of endodontic therapy with improved disinfection and ablation characteristics may feature the use of an alcohol or polyol-based indocyanine green (ICG) solution with a laser system that emits a wavelength within the maximal absorption range of ICG. By matching the dye and laser output, radiant energy use is maximized for efficient ablation and disinfection of treated tissues. Also, the use of an alcohol or polyol as a solvent for the ICG solution increases the inherent disinfection qualities of the solution itself. In one embodiment, the prepared canal is flooded with the ICG solution and the laser activates with the laser fiber inserted into the solution. In an alternate embodiment, the solution is mostly removed prior to activation of the laser, but only after necrotic tissue has been stained.
