Publication number: 20230372074Abstract: An oral suction device provides an oral suction screen over the oral cavity of a patient by providing upper and lower suction wings attached to a manifold. The wings are inserted between the upper and lower lips and arches of a patient, respectively, and serve to capture aerosols which would otherwise be ejected from the oral cavity. A tongue/cheek retractor, also in pneumatic communication with the manifold, serves to extract saliva and other products from the oral cavity while also preventing the tongue and cheeks from ingress of the workspace for the dental procedure.Type: ApplicationFiled: July 31, 2023Publication date: November 23, 2023Applicant: CAO Group, Inc.Inventors: Densen B.

Publication number: 20230346655Abstract: 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.Type: ApplicationFiled: July 7, 2023Publication date: November 2, 2023Applicant: CAO Group, Inc.Inventors: Steven D.

Patent number: 11622835Abstract: 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.Type: GrantFiled: May 31, 2022Date of Patent: April 11, 2023Assignee: CAO Group, Inc.Inventor: Steven D.
