  • Publication number: 20240131211
    Abstract: An UV disinfection system (200) may feature a chamber (207) with internal spherical reflective surfaces (208) to evenly reflect UV radiation from all angles to direct the UV radiation to all surface area of the object inside the chamber to disinfect object utilizing UV radiation under controlled time. An object (215) to be disinfected may reside within the chamber (207) on a UV transparent rack or shelf (214). The spherical reflective surfaces may be fashioned by placing such surfaces on a polyhedral internal structure or making the internal chamber spherical in and of itself (208). Multiple UV sources (209a), (209b) may also be utilized.

  • Publication number: 20240065761
    Abstract: A laser system for hard and soft biological tissues utilizes a laser (206), dye spray applicator (205), and a rinse spray applicator (212) in concert within a single handpiece (200) to create a computer programmable system that delivers a precise means of controlled ablation. The handpiece (200) is first used to apply dye (209) to a targeted treatment surface (210). Then it is used to apply a laser beam to the dyed treatment surface. This is followed by applying a rinse agent (215) through the same handpiece (200) to remove debris and combustion by-products. The steps are then repeated until the operation is complete.

  • Publication number: 20240000543
    Abstract: An improved method of endodontic therapy utilizes two strategies to create long lasting and effective dental restoration. After a root canal is prepared by conventional means, a dye is flooded into the canal to stain residual infected tissue. The dye is selected to enhance the absorption of radiant energy by dyed tissue by matching at least one ?max of the dye to the output of a laser. The radiant energy (24) from the laser is then used to obliterate all infected root tissues (16) remaining within the prepared root canal (14). Laser treatment extends from the root apex (12) to the tooth corona (18). Second, cements utilizing an anti-microbial agent such as zinc pyrithione are used to restore the tooth, giving the restoration inherent anti-microbial properties. While ideally used together, each strategy may also be utilized on its own for improvement over the prior art.

  • Publication number: 20230404871
    Abstract: The present invention is a formable dental treatment tray utilizing poly(2-ethyl-2-oxazoline) and a gelatinous active. Blending of the active is accomplished by mixing the Poly(2-ethyl-2-oxazoline) with an active ingredient, such as a peroxide like hydrogen peroxide, carbamide peroxide, sodium perborate, or sodium percarbonate, usually also with water or an appropriate organic solvent. Peroxide concentrations in these new gels can reach a 30% concentration of hydrogen peroxide while maintaining a shelf life of six months at room temperature without developing peroxide decomposition. The gels are applied to an appropriate backing and dried to a gelatinous state. In use, the active is hydrated and regains adhesiveness. Then the tray is pressed and formed around a user's dental arch to form the customizable tray. Multiple active ingredients may be used, with or without peroxide, for accomplishing desired treatment regimens.

  • Publication number: 20230380932
    Abstract: 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.
