Can dental assistants legally scale calculus from teeth after completing the coronal polishing course?

Dental assistants are not permitted to scale calculus from teeth as this procedure typically falls outside the scope of practice for their role. Scaling involves the removal of plaque and calculus from teeth, which is a function reserved specifically for licensed dental hygienists and dentists. The training received in a coronal polishing course does not extend to scaling practices; instead, it focuses on polishing teeth and enhancing their aesthetic appearance, which does not involve invasive procedures.

Thus, the correct response reflects the legal limitations placed on dental assistants concerning the practice of scaling. Understanding these regulations is crucial for ensuring patient safety and adhering to professional standards in dental care.
