<P>PROBLEM TO BE SOLVED: To provide a dental scaling/disinfecting device in consideration of high-temperature sterilization treatment by an autoclave or the like, and having excellent workability. <P>SOLUTION: This dental scaling/disinfecting device transmits ultrasonic vibration generated by an ultrasonic vibrator 12 to a tip part of a probe 20 to smash tartar, supplies a disinfecting solution supplied by a liquid supply means from the probe tip part to a tooth part, guides and irradiates light from a light source device 11 to the supplied disinfecting solution by a light guide 20 to generate hydroxyl radical for disinfection. The light source device 11 has: a semiconductor light source 111 emitting light of a predetermined wavelength region; a condenser lens 112 condensing the light emitted from the semiconductor light source; and a cylindrical member. The cylindrical member has a large diameter part 113 and a small diameter part 114 holding the condenser lens and the semiconductor light source in predetermined positional relation, and the large diameter part 113 is positioned outside a holder 10 holding the probe. <P>COPYRIGHT: (C)2013,JPO&INPIT |
