The effectiveness of an actuator-driven pulsed water jet for the removal of artificial dental calculus: a preliminary study

摘要

Schematic diagram (a) and photograph (b) of the piezo ADPJ system. The ADPJ is generated by the movement of piston driven, the water is released through the chamber continuously. The three-dimensional water flow ejected from the nozzle can be adjusted with a manual switch, and the water volume and speed are easy to control. Dissected tissue and splashed and excess liquid are aspirated through the removable silicone suction tube connected to a conventional aspirating system in the operating theater. ADPJ: actuator-driven pulsed water jet, CP: stainless steel connecting pipe, Di: stainless steel diaphragm, PA: piezo electric actuator
