Abstract
A dental implement is disclosed that uses a conventional tank of pressurized medical grade nitrogen, a flow control box downstream from it that receives input from a standard dentist's handpiece airflow control, a mixing chamber that holds the abrasive and includes a secondary nitrogen flow line that will 'fluff up' the abrasive when sufficient gas flow is allowed to pass through it, thus entraining the abrasive within the nitrogen flow, and a handpiece that has a directing nozzle for application of the flow on a specific worksite with a fiber optic bundle having a replaceable, resilient light transmissive tip to direct light on the worksite.
