ABSTRACT:
An apparatus is provided for processing combined liquid and solid dental waste from a patient's mouth such that the solid waste is separated from the liquid waste. The solid and liquid dental waste are removed from the patient's mouth and transmitted to a separation chamber. The liquid waste is substantially eliminated from the separation chamber to leave a solid waste residue therein. The solid waste residue is then collected from the separation chamber.
