Step-by-step explanation:
The statement is True: Responsibilities of the dental assistant in the restorative process can include performing expanded function and maintaining patient control. Dental assistants are trained to perform a variety of tasks to support dentists during the restorative process. The specific responsibilities may vary by region and local regulations, but often include preparing the work area and tools, assisting during procedures, follow-up care instructions to patients, and maintaining a sterile environment. In some cases, dental assistants with additional training are permitted to perform expanded functions such as placing and finishing dental fillings under the direct supervision of a dentist. Maintaining patient control involves ensuring that the patient is comfortable, managing behavior during the procedure, and monitoring the patient's condition throughout the treatment.
