Minnesota Dental Jurisprudence Practice Exam

Which of the following functions can a licensed dental assistant perform when the dentist is out of the office?

1. Dry root canals with paper points

2. Pre-select orthodontic bands

3. Take radiographs

4. Remove temporary restorations

The correct answer is: Take radiographs

A licensed dental assistant has specific responsibilities and tasks they are allowed to perform under Minnesota state law, particularly when a dentist is not present in the office. Taking radiographs, or dental X-rays, is within the scope of practice for a licensed dental assistant. This task requires appropriate training and certification, ensuring that the assistant is qualified to produce diagnostic radiographs while adhering to safety protocols. The role of the dental assistant is essential in supporting dental procedures and patient care. In Minnesota, they are granted the authority to perform specific duties to facilitate the workflow in a dental practice, even in the absence of the dentist. Other tasks, like drying root canals or removing temporary restorations, typically require direct supervision or the presence of a licensed dentist, as they involve more complex procedures necessitating professional judgment and expertise. Pre-selecting orthodontic bands might also fall under the area of indirect patient care that is best performed under the dentist's direction. Therefore, taking radiographs aligns with the responsibilities designated for a licensed dental assistant, making it the correct answer.
