ABSTRACT:
A method of preventing a back flow of oral contaminants in a low volume suction line of a dental saliva ejector is described. This method consists of the single step of placing a vacuum release aperture through a tubular sidewall of a saliva ejector tip. The aperture is spaced from a mouthpiece of the saliva ejector tip such that when the mouthpiece is inserted into a patient's mouth, the patient's mouth will not block the aperture.
