Abstract
A self cleaning dental mirror apparatus utilizing the fluid dynamic properties of water and air to siphon the water across the reflective surface by air pressure through nozzle flanges surrounding a portion of the rim of the mirror surface, thus allowing the dentist free and continuous use of the dental mirror apparatus without interference from debris, mist and sprays normally produced in everyday dental operations. The apparatus is adaptable to standard dental consoles with means to regulate, measure and control all fluids separately or simultaneously and to provide a regulating means to control the amount of surface tension reducer operating through the water system.
