ABSTRACT:
Apparatus for aspirating liquids and debris which collect near the working region of a dental dam. The apparatus includes a head adapted to extend removably and sealingly through a stretched aperture in such a dam, with the head having aspirating ports that open on opposite surfaces of the dam. These ports couple with an exhaust passage, which extends on the nonworking side of the dam, and which is adapted for coupling to a flexible suction conduit.
