An aspiration unit that can be readily connected to an ultrasonic scaler of conventional design which includes a novel suction means for automatically carrying away from the work site cooling water and debris generated during the performance of the scaling procedure. The unit includes a transparent, tip-encompassing shroud that uniquely functions as a suction scoop for automatically capturing aerosols in the operative field including aerosols containing saliva, blood, tissue, calculus and like adherent deposits which are generated during the scaling procedure. The aspiration unit includes novel connectors that enable the unit to be removably connected to a conventional scaler so that the assemblage can be operated by the dentist using one hand without the aid of a dental assistant thereby decreasing the number of people exposed to any pathogens encountered during the scaling procedure.
