Abstract: An operatory light may comprise a bulb that includes a light emitting diode (LED) module positioned such that when the bulb is installed into a socket of the operatory light and powered, none of the light emitted from the LED is directed directly toward a lens of the operatory light, and only reflected light passes through the lens of the operatory light.

Abstract: 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.

Abstract: 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.
