  • Dental laser apparatus and method for ablating non-metallic dental material from a tooth
    Patent number: 5554029
    Abstract: A method of ablating non-metallic dental material from a tooth comprises the steps of generating radiation pulses having a predetermined wavelength, energy level, pulse repetition rate, and duration, and applying the radiation pulses to the non-metallic dental material in a tooth, whereby the non-metallic dental material is ablated from the tooth. The radiation may be generated by a frequency tripled Nd:YAG, an Er:YAG laser or an Er:YsGG laser and may have a wavelength of about 355 nanometers, 2.94 micrometers, and 2.79 micrometers respectively, for example.

  • Dental laser apparatus and method for treating tooth decay
    Patent number: 5281141
    Abstract: A dental laser apparatus and method is disclosed for removing tooth decay. A substance which selectively attaches to tooth decay is applied to the tooth. This substance has a predetermined absorption band. A laser having an output wavelength which corresponds to the absorption band is supplied and is absorbed primarily by the decayed portions of the tooth. The use of Acid Red 52 dye as the substance and a frequency doubled Nd:YAG laser as the source is disclosed as one embodiment.
