摘要： The present invention is a dental evacuation tool for being placed in fluid communication with a dental vacuum. The tool comprises a suction head and an elongated tubular handle. The suction head includes a mirror surface, first and second upward-facing intake orifices adjacent the mirror surface, and an exit fluid pathway that is in fluid communication with the first and second upward-facing intake orifices. The elongated tubular handle includes a first end adapted to be in fluid communication with the vacuum and a second end in fluid communication with the exit fluid pathway. The first and second upward-facing intake orifices are positioned generally opposite each other about the mirror surface, are generally centered about a line that is generally perpendicular to the longitudinal axis of the handle, and open in generally the same direction faced by the mirror.
