Abstract
A saliva ejector tip system, which prevents the problem of backflow when a patient closes his lips around an ejector tip, includes seal-interfering structural features on the outer surface of an ejector tip. A tip holder carried by a saliva elector hand tool couples with the proximal end of the tip in vacuum-tight engagement.
