COMPARISON STUDIES BETWEEN CONVENTIONAL HYPERTHERMIA AND ND: YAG LASER HYPERTHERMIA

Abstract

To use laser hyperthermia (laserthermia) as a form of cancer therapy in the field of oral surgery, we have conducted several basic studies. Using normal tongue of rabbits, we recently investigated the differences between hyperthermia by laser light and by other means. More specifically, we experimentally compared the effects of the artifical sapphire probe commonly used for laserthermia and a new titanium probe of the same form which tansmits heat but not laser light.
Results:
1) Ultrasonography showed that laserthermia penetrated deeper into the tissue than conventional hyperthermia.
2) Histro-pathological examination revealed that laserthermia has greater invasiveness than conventional hyperthermia.
3) Biochemical examination revealed that laserthermia has greater change than conventional hyperthermia on lipid peroxide levels.
