Novel Design, Control and Fabrication of Automated Paste Polishing System

Periodontal polishing is the act of smoothing the tooth surface and performed by hand-piece device and addition of prophylaxis paste onto the bristle brush by the dentist. Disadvantages of this technique include non-uniform cleaning of tooth surface and removal of dental deposits including dental plaque and long duration of head substitution due to paste running out and other factors. To solve this problem, a new machine was designed capable of adding the prophylaxis paste to the hand-piece apparatus head automatically. This setting injects the prophylaxy paste into the target point with pneumatic automatic control system. This paper deals with design and fabrication of pneumatically operated automatic paste machine. The pulse and pressure system control for pneumatic system were designed and implemented. The manually operated machine is converted into a pneumatically operated machine by applying proper ergonomically design procedure. Findings support the use of automatic pneumatic paste injection instrumentation over the traditional hand paste polishing.
