HESI General Chairside Assisting Practice Exam 2025 – The All-in-One Guide to Achieve Exam Success!

The expanded-functions assistant is the type of assistant legally allowed to perform intraoral procedures. This role is specifically designed for those who have received additional training and certification to carry out a wider range of clinical tasks beyond those of a traditional chairside assistant. Expanded-functions assistants can perform duties such as coronal polishing, sealant application, and certain procedures that involve working directly within the patient's mouth, under the supervision of a licensed dentist.

Meanwhile, chairside assistants typically assist during procedures but do not perform invasive tasks themselves. Dental hygienists focus on preventive oral care, including cleanings and patient education, and while they do perform intraoral procedures, their role is distinct from that of dental assistants. Receptionists are administrative staff and do not perform clinical tasks related to patient care. Hence, the expanded-functions assistant stands out as the one legally empowered and trained to undertake intraoral procedures.
