DPll ISOLATOR SYSTEM is a low cost, easy to learn system that provides retraction of the tongue,provides suction,and with the use of the mouth prop can isolate the lower areas of the mouth for most dental procedures. This is the second generation of the original DentaPop. The biggest difference is the elimination of several individual parts of the DentaPop. The tongue retractor and aspirator are now one unit which can be autoclaved and used over and over. The mouth prop is the only disposable part and can be used without the tongue retractor when needed. The grey universal tubing can be used with your HVE or LVE with the use of a small clear removable connector coupling shown in the picture below. The tubing is extremely light weight and when not using the DPll, a regualr low vac saliva ejector can be attached for dental hygiene procedures. The small pinch clamp slides along the tubing and can be used to control amount of suction. All of the parts of the DPll SYSTEM can be purchased separately. Since the one piece tongue retractor/aspirator are autoclavable only a few are needed to get started.
