  • Publication number: 20070298369
    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.

  • Publication number: 20070190482
    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.

  • Publication number: 20070042315
    Abstract: An electromagnetic energy output device in the form of laser handpiece and a trunk assembly is disclosed. The electromagnetic energy output device includes a digital camera and electromagnetic energy waveguides for emitting illumination or excitation light energy to enhance user viewability of a target surface and signal analysis and to receive electromagnetic energy such as return excitation light.

  • Publication number: 20070014322
    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: 20060241574
    Abstract: Output optical energy pulses including relatively high energy magnitudes and steep slope 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 steep 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 50-70 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 about 50 microhenries and a capacitor which has a capacitance of about 50 microfarads. The output optical energy pulses cut target surfaces by interacting with fluid that is located above, on and/or in the target surface. Methods are disclosed for therapeutically treating tissue with pulses of electromagnetic energy.
