Question

A typical task of a dental assistant is applying compressed air. Why is this done?

A) To clear saliva and debris or to dry a tooth surface.
B) To numb the gum and surrounding area.
C) To check an area for swelling or lesions.
D) To apply paste or cleaning solutions to teeth surfaces.

Answer 1

Applying compressed air in dental procedures is done to clear saliva and debris or to dry a tooth surface for treatment. Keeping the work area moisture-free is crucial for procedures requiring adhesion, such as fillings. The correct answer is A) To clear saliva and debris or to dry a tooth surface.

Step-by-step explanation:

The task of applying compressed air by a dental assistry ant is typically done for clearing saliva and debris or to dry a tooth surface before certain dental procedures. Saliva, which is secreted by the salivary glands, aids in digestion and dental health, but can interfere with dental treatments. It keeps teeth clean and contains antibodies that protect against infection but needs to be managed during dental work.

To create a clean and dry working area, which is essential for many treatments and the adhesion of materials like fillings or sealants, compressed air is a practical tool. Dry tooth surfaces are especially critical when applying restorative materials such as composites that require a moisture-free environment for proper bonding. Thus, the correct answer to the question is A) To clear saliva and debris or to da tooth surface.
