  • Device and process for curing a photocurable plastic filler
    Patent number: 6065965
    Abstract: A deice for curing a photocurable plastic filler (6) disposed in a dental cavity (2) of a hard tooth substance (4) includes a laser light source (10) and a light conductor (11) leading from the laser light source (10) to an applicator (14). The applicator (14) is utilized to apply drops of the plastic filler (6) upon the dental cavity alternating with an intermittent operation of the laser light source (10).

  • Device for removing carious tooth material by laser light and use of a laser light source
    Patent number: 5501599
    Abstract: A method of removing carious tooth material is effected by creating a laser light beam from a pulsed laser light source, and utilize a flexible light guide to direct the laser light beam as a light spot on carious tooth material of a tooth. The light source has a wavelength in the range from substantially 320 to 520 nm and the energy density per pulse in the light spot is substantially 0.14 to about 7.0 J/cm.sup.2.
