The interaction mechanisms of Q switch ruby laser pulse with stomatology prosthetic materials (wisil, wironit, amalgham, helia progress, 'bridge" and palador) is analyzed. Certain samples were exposed to X and gamma rays and electron beams beforelaser irradiation. Very short coherent pulsed laser beams in series of experiments were applied . induced damaged and surface changes were analyzed by light and electron microscopy methods and computer imagine processing. Possible laser applications wereestimated in the function of beam energy and wavelength range.
