About saliva ejectors
A dental unit carries two evacuators attached to one vacuum source: a high-volume evacuator and a low-volume evacuator. The low-volume line is the one used to draw off blood, saliva and the coolant from the drill so that the working area stays clear. Low-volume evacuation is useful for removing pooling saliva and water, but it does not have the power to limit the spread of droplets generated during a procedure.
Backflow from low-volume saliva ejectors occurs when the pressure in the patient’s mouth is less than the pressure in the evacuator. The CDC reports that studies have found backflow in low-volume suction lines can occur, and microorganisms present in the lines be drawn back into the mouth when a seal forms around the ejector, for example when a patient closes the lips around the tip. How often it happens varies, because the quality of the seal formed varies between patients. Studies have also shown that gravity pulls fluid back toward the mouth whenever a length of the suction tubing holding the tip is positioned above the patient’s mouth, or while other high-volume evacuation equipment is in use at the same time.
No adverse health effects associated with the saliva ejector have been reported, and the CDC says practitioners should be aware that in certain situations backflow could occur when one is used. Its recommendation is not to advise patients to close their lips tightly around the tip of the saliva ejector to evacuate oral fluids. Saliva ejectors are commonly available in a disposable form, and the CDC says such items should be disposed of appropriately after each use.
What to look at when choosing a saliva ejector
Suction cannulas come in different diameters: one splatter study compared a 6 mm saliva ejector, an 11 mm suction cannula and three types of 16 mm suction cannula.
A single-use device is designed to be used on one patient and then discarded, not reprocessed for use on another, and single-use devices in dentistry are usually not heat-tolerant and cannot be reliably cleaned.
The handle it plugs into: the handles and dental unit attachments of saliva ejectors do not enter the mouth but are likely to become contaminated with oral fluids, so the CDC says they should be covered with impervious barriers that are changed after each use.
Bacteria and biofilms sit steadily in the pipeline connected to the evacuators, which gives them a surface to form, grow and multiply on and shed from.
Amalgam work: a national standard counts saliva ejectors used in dental procedures involving amalgam as amalgam waste.
