Laser apparatus for treating hard tissues and method for using the apparatus

摘要

A semiconductor laser apparatus combined with a chromophore and a method for using them in treating hard tissues, such as for example dental tissue, in which elements ( 3 ) for applying a chromophore in the area of the tissue to be treated are coupled to a semiconductor laser ( 4 ), elements for conveying ( 5, 6 ) the laser light and for focusing ( 7 ) the laser light on the tissue to be treated also being coupled to the laser; the chromophores can be chosen among different chromophorous agents and must have a high coefficient of absorption at the wavelength of the laser chosen for the type of treatment and/or tissue to be treated.
