TREATMENT DEVICE AND TREATMENT METHOD

摘要

A dental treatment device (1) has an irradiation section (10), a temperature detection section (20), and a control section (30). The irradiation section (10) is constructed by combining, in a one-to-one relationship, N number of first light emitting elements (S<SUB>1</SUB>-S<SUB>N</SUB>), N number of first light collecting lenses (L<SUB>1</SUB>-L<SUB>N</SUB>), and N number of optical fibers (F<SUB>1</SUB>-F<SUB>N</SUB>). Optical fibers (F<SUB>n</SUB>) are bundled on the output side of the irradiation section (10). A first light emitting element (S<SUB>n</SUB>) is an element outputting a laser beam of a specific wavelength ? in the range of 400 nm-420 nm. The temperature detection section (20) is made up of a contactless temperature sensor (22) and a wire (24). The contactless temperature sensor (22) detects the temperature of a portion irradiated with a laser beam outputted from an emission end.
