Can a dental assistant legally perform a simple prophylaxis for a child?

In Nevada, the practice of dentistry is strictly regulated, and certain procedures are reserved for licensed dentists. A dental assistant, while trained to assist with various tasks in the dental office, is not authorized to perform simple prophylaxis, which is a preventive procedure that involves cleaning teeth and removing plaque and tartar. This is considered a dental procedure that requires the clinical judgment and expertise of a licensed dentist.

Prophylaxis involves the assessment of dental health, identification of potential issues, and the application of specific techniques and instruments that should only be carried out by a professional who holds the appropriate dental license. Therefore, without being a licensed dentist, a dental assistant cannot legally undertake this task, aligning with Nevada's regulations on the scope of practice for dental assistants.

The other options present scenarios influenced by varying regulations or conditions, but in the case of Nevada law, a dental assistant’s inability to legally conduct a simple prophylaxis stands firm.
