ABSTRACT:
A laser cutting apparatus is disclosed which includes a laser emitter capable of outputting a laser beam in pulses, a laser beam irradiation member, and a dental-crown polishing and washing member. The dental-crown polishing and washing member has an injection member through which air, water and polishing material are output toward a laser-beam-irradiated surface. A control member is provided which is capable of controlling the operation of laser emitter and dental-crown polishing and washing member. The laser beam irradiation member and injection member are combined with each other by means of an adapter disposed therebetween, thereby enabling both of laser beam irradiation member and injection member to be held and operated by a single hand. By employing this laser cutting apparatus, a high-energy laser beam can be used in the medical and dental fields for removing soft dentin to form a cavity. This apparatus does not have problems due to irradiation of a high-energy laser beam, such as the production and residue of a carbonized layer in the dentin, formation of a fused layer in the dentin, occurrence of a cavity margin having an irregular configuration, and cracking and damaging of the dental pulp attributed to a temperature rise.
