Abstract
A double-sided mirror and irrigation instrument for intraoral application has an in-line finger operated valve for selectively controlling flow of air, water or a mixture of air and water through an annular supply passage for cleaning the mirror surfaces and objects in the oral cavity. An annular suction passage extends from the mirror assembly through an extension tube for draining liquids from the patient's mouth. The mirror assembly is illuminated by light transmitted through a quartz rod that is enclosed within a central supply conduit.
