ABSTRACT:
A saliva ejector including a hollow tube operably associated with a tongue protector. The tube includes first and second ends and a hollow cavity extending therebetween. The tongue protector is permanently secured to the tube by a solder having a minimum composition of 55% silver. The tongue protector is removed from the hollow cavity of the tube. The first end of the tube is adapted to be inserted into a patient's mouth and the second end is adapted to be operably associated with a vacuum system. The tube includes at least one aperture extending transversely therethrough and communicating with the hollow cavity thereby defining a passageway for saliva and the like to pass through. The tube has substantially constant inner and outer diameters.
