ABSTRACT:
A dental suction mirror has a stainless reflecting plate with a slant depression and an oblong groove 13. Three holes having different paths in the inner center and on both sides of the plate connect the groove to the depression. A stainless connection tube having an expanding portion in the form portion thereof and a projecting tube in the rear portion thereof; and a handle tube having an insertion groove along the upper part thereof are connected to the plate. An optical fiber is in the insertion groove, stickers being applied to the groove so as to prevent the optical fiber from leaving the groove. A plastic clip over a narrow portion of the stainless tube curves the optical fiber upwardly over a polished specular surface, and the stainless reflecting plate, the stainless connection tube and the handle tube are coated with nickel-chrome and additionally SiO.sub.2.
