A cancer treatment with improved effectiveness may feature emission of radiant energy from a laser source based upon measured parameters, particularly melanin content, in a patient's surrounding tissues. Multiple wavelengths of radiant energy, pulse durations, and intensities may be utilized in the radiant energy emission based upon the patient's tissue parameters. One embodiment of a laser source features multiple laser modules () which may be independently operated and adjusted for intensity and active duration.

Non-invasive multi-wavelength laser cancer treatment

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.

Laser endodontic procedures utilizing alcohol based indocyanine green solutions

A method of accurately and precisely measuring the volatile solvent content of tooth whitening compounds incorporates taking a representative sample of the compound at a given stage of manufacture and measuring its weight before and after a heating process to eliminate substantially all the volatile solvents contained within the sample. By comparing initial and finished weights, the percentage of volatile solvents may be obtained. The process may then be repeated throughout the manufacturing process until any desired solvent concentration is reached.

Materials and methods of determining the amount of volatile solvents in teeth whitening compositions

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.

A light source includes a socket connection, a base connected to the socket connection, an LED unit, a mount and a heat conductive material. The socket connection is capable of connecting to a source of electricity. The mount is disposed into the base, and has a top surface on which the LED unit are disposed and a side surface devoid of the LED unit. The heat conductive material directly contacts the LED unit and the side surface of the mount. The heat conductive material enters into a space flanked by the mount and the base and is substantially translucent or transparent such that light emitted from the LED unit is able to pass through the heat conductive material.

A dental bleaching device may include a backing material made of a polymeric wax mixture, and a dental composition in contact with the backing material. The dental composition may include a thickening agent and a peroxide bleaching agent. The dental composition may be a gelatinous compound having physical deformation properties that allow the dental composition to bend and conform to a shape of a container into which the dental composition is placed, but the dental composition will not merge into a second piece of the dental composition when placed in contact with the second piece.

Example embodiments of the present invention include various compositions that include a pH modifier composition and/or a buffering capacity modifier composition. In some examples, the pH modifier compositions include a dose of pH modifier to raise the pH in a patient's mouth from about 1 to about 2 pH levels. The compositions are then incorporated into various confections for oral ingestion or application that allow a patient to easily use the composition with the pH and/or buffering capacity modifiers. For example, compositions with the pH and/or buffering capacity modifiers can be incorporated within chewing gum, tablets, lozenges, breath strips, hard candy, oral sprays, and other confections. Another embodiment of the invention includes a testing device to test the pH and buffering capacity within a patient's mouth.

Oral pH and buffering capacity modifiers

A dental bleaching device may include a flexible backing material, and a dental composition in contact with the flexible backing material. The dental composition may include a thickening agent and a peroxide bleaching agent. The dental composition may be a gelatinous compound having physical deformation properties that allow the dental composition to bend and conform to a shape of a container into which the dental composition is placed, but the dental composition will not merge into a second piece of the dental composition when placed in contact with the second piece. The dental composition will not crack or break when the dental bleaching device is flexed.

Embodiments of the present invention include methods, devices, and systems that light and magnify a treatment site within the oral cavity without interfering with a dental treatment procedure. In particular, example embodiments of the present invention provide a virtual operatory system that includes an image capture subsystem connected to an image display subsystem. For example, the image capture subsystem can capture and communicate a live image of a treatment site to the image display subsystem for the dental professional to view while performing a dental treatment procedure. In at least one example embodiment, the virtual operatory system can also include an image rendering subsystem that can render the live image of the treatment site in one or more ways to provide an improved visual to the dental professional of the treatment site.

Virtual dental operatory

A method of removing a dental adhesive may comprise locating the position of the dental adhesive, directing radiant energy into the dental adhesive causing the dental adhesive to weaken a bond formed with the dental adhesive, and breaking the bond by applying a suitable force to overcome the weakened bond. A dental adhesive may comprise a polymer and a dye or pigment, The dental adhesive may be formulated to cure to form a bond that is weakened in response to the dye or pigment absorbing radiant energy subsequent to curing.

Reversible dental adhesive

A delivery tip for flowable materials with bristles or fibers extending therefrom. The tip is a cannula with a tapered outlet and features a bristle or fiber bundle with a binding restriction member that interfaces with the cannula at some point within the cannula but has a smaller cross-sectional area for flow passage than the cannula at that point. The bristle or fiber bundle extends out of the tapered outlet. The delivery tip may connect to a material reservoir with flowable material. When positive pressure is applied to the reservoir, material then will flow through the cannula, around the restriction member, into the bristles or fibers and out the outlet for distribution to a desired surface.
