What is a special delegated duty that a dental assistant may perform?

The application of pit and fissure sealants under specific conditions is a special delegated duty that a dental assistant may perform because it falls within the scope of practice that many states allow for dental assistants, provided they have received proper training and the supervising dentist has established the appropriate protocols. This task is considered preventive care that helps protect teeth from decay and is typically within the dental assistant's duties when performed under the guidelines set forth by dental boards or regulations.

In contrast, making intraoral occlusal adjustments, administering local anesthesia, and performing root planing procedures typically require more extensive training and are generally reserved for licensed dental professionals such as dentists or hygienists. These procedures involve a higher level of skill and knowledge regarding oral health and anatomy, which are beyond the standard training provided to dental assistants. Therefore, these duties are not considered special delegated duties that dental assistants can perform.
