What does the term "saliva ejector" refer to in dental equipment?

The term "saliva ejector" refers to a type of low-volume evacuator that is commonly used in dental procedures. This device is designed to remove saliva and other debris from the patient's mouth during dental treatments, helping to keep the area clean and dry. By doing so, it enhances visibility for the dentist and improves the patient's comfort throughout the procedure.

Unlike a high-volume evacuator, which is used for suctioning larger volumes of fluids and is typically utilized in more invasive procedures, the saliva ejector operates at a lower suction level. This makes it suitable for routine procedures such as cleanings and examinations, where the goal is to manage moisture without creating excessive suction.

The other options, while related to dental practice, do not accurately define a saliva ejector. For instance, devices for administering medication are distinct from suction devices and serve an entirely different purpose. Similarly, high-speed drilling tools are used for cutting through tooth structure, and tools for whitening teeth focus on cosmetic procedures, rather than managing saliva in the mouth.
