Abstract: An instrument is provided to enables a dental professional to subject a surgical site simultaneously to (1) mechanical cutting, scraping and grinding, and (2) laser trimming and cauterization. As a result, simultaneous removal of diseased tissue and destruction of residual bacteria is enabled. The instrument comprises a hollow shank having, a rearward fitting, and a forward contact head. Within shank extends a fiber optic bundle. As shown, laser energy is delivered from a laser through the fitting and the laser bundle to the contact head. In the contact head are a surgical blade and an exit window for the laser energy.

Abstract: Optical methods and devices are provided for the reduction of the lipid content of adipocytes without significant heat or intolerable adverse effect on the cells and their surrounding tissues. The optical method and device can be used to irradiate adipose tissue through the skin with non-thermal and non-destructive effects by application of near infrared (NIR) irradiation at selected wave bands in selected ranges to affect modulation of innate enzymatic processes involved in lipolysis, lipogenesis, leptin secretion, adiponectin secretion, and/or glucose absorption.

Abstract: A system and process for thermolytic eradication of bacteria and biofilm in the root canal of a human tooth involve an elongated and flexible optical probe and a laser oscillator that provides the probe with low infrared energy. The optical probe is sufficiently long for insertion into substantially the entire length of the root canal of the tooth. The optical probe causes lateral dispersion of the radiation from the probe throughout the root canal. The radiation is provided at an energy density and for a period of time that are necessary to selectively target bacteria and live biofilm in the dentinal tubules of an entire root canal system, at once, thereby (1) inhibiting creation of a blackbody “hot tip”, and (2) inducing laser interstitial thermotherapy (LITT) within the root-canal space.

Abstract: Dual wavelength laser energy in the low infrared electromagnetic spectrum destroys bacteria via photo-damage optical interactions through direct selective absorption of optical energy by intracellular bacterial chromophores. The dual wave length laser system includes an optical assembly including two distinct diode laser ranges (870 nm diode array and 930 nm diode array) that can be emitted to achieve maximal bacterial elimination.

Abstract: A dual wavelength laser in the low infrared electromagnetic spectrum is disclosed for destruction of bacteria via photo-damage optical interactions through direct selective absorption of optical energy by intracellular bacterial chromophores. The dual wavelength (NIMELS) laser includes an optical assembly and all associated components necessary for the housing of two distinct diode laser arrays (870 nm diode array and 930 nm diode array) that can be emitted through an output connector and wavelength multiplexer as necessary. With this preferred design, the dual wavelengths (870 nm and 930 nm) can be emitted singly, or multiplexed together to be conducted along a common optical pathway, or multiple optical pathways, to achieve maximal bacterial elimination.
