  • Patent number: 7424199
    Abstract: A fiber tip fluid output device is provided for holding a fiber tip in an electromagnetic energy cutting apparatus and for directing water particles over a radiation delivery end of the fiber tip. The fiber tip fluid output device includes a generally cylindrical body having an outer surface, a proximal end, a distal end, and a lumen extending between the proximal end and the distal end. The lumen is sized and shaped to accommodate a fiber tip therethrough so that the fiber tip extends through the lumen from the proximal end to the distal end of the generally cylindrical body. The fiber tip fluid output device further includes a plurality of apertures extending around the generally cylindrical body, with each of the apertures of the plurality of apertures fluidly connecting the outer surface to the lumen. Fluid is mixed around the cylindrical body, before entering the lumen through the plurality of apertures for additional mixing.

  • Patent number: 7415050
    Abstract: Output optical energy pulses including relatively high energy magnitudes at the beginning of each pulse are disclosed. As a result of the relatively high energy magnitudes which lead each pulse, the leading edge of each pulse includes a relatively large slope. This slope is preferably greater than or equal to 5. Additionally, the full-width half-max value of the output optical energy distributions are between 0.025 and 250 microseconds and, more preferably, are about 70 microseconds. A flashlamp is used to drive the laser system, and a current is used to drive the flashlamp. A flashlamp current generating circuit includes a solid core inductor which has an inductance of 50 microhenries and a capacitor which has a capacitance of 50 microfarads.

  • Publication number: 20080138764
    Abstract: A fluid conditioning system is adapted to condition the fluid used in medical and dental cutting, irrigating, evacuating, cleaning, and drilling operations. The fluid may be conditioned by adding flavors, antiseptics and/or tooth whitening agents such as peroxide, medications, and pigments. In addition to the direct benefits obtained from introduction of these agents, the laser cutting properties may be varied from the selective introduction of the various agents.

  • Patent number: 7261558
    Abstract: A cleaning and whitening system for teeth having an electromagnetic radiation emitting toothbrush and a dentifrice with a photosensitive agent is disclosed. The toothbrush has a cleaning surface, such as bristles. The toothbrush is also adapted to direct electromagnetic radiation toward the cleaning surface. The electromagnetic radiation may be monochromatic or polychromatic. Further, the electromagnetic radiation may be substantially free of ultraviolet radiation. Additionally, the electromagnetic radiation may consist essentially of wavelengths within a range of 300 to 750 nanometers. The photosensitive agent is dispersed throughout the dentifrice. The dentifrice transmits the electromagnetic radiation through a varying thickness disposed over a target surface during use of the system. As a result, a significant portion of the photosensitive agent reacts, resulting in whitening stains, removing and/or disclosing undesired substances, and/or foaming.

  • Patent number: 7144249
    Abstract: A dental device for exposing teeth to electromagnetic radiation includes a carrier and at least one source of electromagnetic radiation attached to the carrier and oriented so that the electromagnetic radiation is emitted from the source to a surface of a tooth. The dental device may also include a power source internally or externally disposed with respect to the carrier, and may include a circuit for controlling radiation emitted from the source. The dental device may be used for whitening teeth, and dental hygiene in general. Related methods are also disclosed.
