What is the function of an ejector in dentistry?

1. A device used for suctioning debris and fluids

2. A method for performing teeth whitening

3. A tool for measuring gum depth

4. A type of dental x-ray

The correct answer is: A device used for suctioning debris and fluids

An ejector in dentistry primarily serves the function of suctioning debris and fluids from the oral cavity. This device, often referred to as a saliva ejector or aspirator, plays a crucial role in maintaining a clean and dry environment during dental procedures. By efficiently removing saliva, blood, and other fluids, the ejector helps the dental professional visualize the treatment area more clearly and reduces the risk of contamination during procedures. The other options involve different dental tools or procedures. Teeth whitening methods involve bleaching agents and specific techniques, measuring gum depth typically uses periodontal probes, and dental x-rays are imaging tools for diagnosing issues within the teeth and jaw. Each of these has distinct purposes that differ significantly from the suctioning function of an ejector.
