ABSTRACT:
A method of cutting physiologic tissue in the mouth of a patient, comprising: providing a tunable laser which is tunable to produce laser radiation at any one of at least two different wavelengths, including a first wavelength which is effective for cutting physiologic tissue of a first type and a second wavelength for cutting physiologic tissue of a second type; tuning the laser to produce radiation at one first and second wavelengths; emitting the radiation being produced by the laser and directing the emitted radiation at physiologic tissue of the type corresponding to the radiation wavelength which the laser is tuned to produce; and at least when the laser is tuned to produce radiation at a selected wavelength, directing a cooling liquid at the physiologic tissue at which the emitted radiation is being directed simultaneously with performance of the directing step.
