Title:

TREATMENT DEVICE AND TREATMENT METHOD

Document Type and Number:

WIPO Patent Application WO/2007/129424

Kind Code:

A1

Abstract:

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 (S1-SN), N number of first light collecting lenses (L1-LN), and N number of optical fibers (F1-FN). Optical fibers (Fn) are bundled on the output side of the irradiation section (10). A first light emitting element (Sn) is an element outputting a laser beam of a specific wavelength λ 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.
