Coronal Polish Certification Practice Test

The correct response states that both a dentist and a dental hygienist are authorized to scale calculus from patients' teeth in a dental office, which is accurate within the scope of dental practice. A dentist, with their comprehensive training and licensing, is fully qualified to perform all procedures related to dental care, including scaling calculus.

Similarly, dental hygienists, who undergo specialized education and training, are specifically taught the skills necessary for performing scaling as part of their role in maintaining oral health. They are licensed professionals who focus on preventive care and the treatment of gum diseases, making them essential members of the dental healthcare team.

On the other hand, while dental assistants provide crucial support in the dental office, they typically do not have the authority or training to perform scaling procedures. Dental technicians, who work mainly in the fabrication of dental appliances and prosthetics, do not engage in direct patient treatment and therefore also lack the scope to scale teeth.

Thus, the inclusion of both the dentist and the dental hygienist in the correct answer captures the professional roles that are legally permitted to perform the procedure in a dental setting.
