True or False: A dental assistant trainee is allowed to work independently after the training period.

The correct response to the question is based on the regulations surrounding the scope of practice for dental assistants in Iowa. A dental assistant trainee is not permitted to work independently after their training period has concluded; they must operate under the supervision of a licensed dentist or dental hygienist. This requirement ensures that the trainee continues to receive guidance and oversight, thereby protecting patient safety and maintaining professional standards within dental practices.

While there might be contexts or specific employer policies that outline different levels of responsibility, the fundamental rule across most jurisdictions, including Iowa, is that dental assistants, including trainees, must work under supervision to provide care and perform clinical tasks. This protects both the patients and the integrity of the dental profession. Therefore, the assertion that they can work independently following their training is inaccurate, affirming the reason why the selected answer is correct.
