Final answer:
Dental assisting trainees can perform certain procedures under the supervision of a dentist, but there are limitations based on state regulations and their level of training.
Step-by-step explanation:
The statement is false. Dental assisting trainees have specific duties and responsibilities that are determined by state regulations and the dentist they work under. While they can perform some procedures under the supervision of a dentist, there are limitations to what they can do without direct supervision. The level of supervision required depends on the trainee's level of training and the specific state laws.
For example, dental assistants may be allowed to take dental impressions or apply sealants without constant supervision, but they may not be able to perform complex procedures like dental fillings or extractions without the dentist present. It is important for dental assisting trainees to understand their scope of practice and work within the limits set by their state regulations.
