Who can perform a dental prophylaxis?

Dentist and dental hygienist
Only a dentist
Dental assistant
Periodontist

The correct answer is: Dentist and dental hygienist

A dental prophylaxis is a routine dental procedure that involves cleaning the teeth and gums to prevent tooth decay and gum disease. This procedure can be performed by both a dentist and a dental hygienist. Dentists and dental hygienists have the necessary education and training to properly perform this procedure. B, C, and D are incorrect options because a dental assistant does not typically have the education or training to perform a dental prophylaxis, and a periodontist specializes in the treatment of periodontal disease and may not perform routine cleanings.
