Which procedure is a dental assistant NOT allowed to perform?

A dental assistant is not permitted to remove calculus, accretions, or stains because such actions typically fall under the scope of practice reserved for licensed dental hygienists or dentists. The removal of calculus and similar substances involves the diagnosis and treatment of periodontal disease, which requires a higher level of training and clinical judgment that dental assistants do not possess.

On the other hand, placing dental sealants, taking dental impressions, and assisting in patient examinations are commonly recognized tasks that dental assistants are allowed to perform under the supervision of a licensed dentist. These activities support the dentist and enhance patient care but do not involve complex clinical decision-making or treatment planning like the removal of calculus does. As such, understanding the scope of practice for dental assistants is crucial to ensure compliance with Florida laws and regulations governing dental practices.
