Patient-to-patient cross-contamination can occur when a patient closes his or her lips around which of the following?

Rinn x-ray holder
saliva ejector
air/water syringe
high-velocity evacuator tip


saliva ejector

Rationale: saliva ejector – Through a process called "suck back," the patient can loosen biofilm from the inside of the saliva ejector hosing and into their mouth via the suction that is created when they release their lips from the saliva ejector straw. Patients don't normally put their lips around the HVE or three-way syringe.
