Question: 1 / 180

Which orthodontic function can be performed under direct supervision by an LDA and hygienist?

Fit orthodontic retainers

Remove fixed ortho bands and brackets

The function that an LDA (Licensed Dental Assistant) and a hygienist can perform under direct supervision is to remove fixed orthodontic bands and brackets. This task falls within the scope of practice allowed for LDAs and hygienists when working under the direct supervision of a dentist. Direct supervision means that the dentist must be physically present in the office while the procedure is performed, providing guidance and oversight.

Removing fixed orthodontic bands and brackets is a task that requires training and skills related to dental materials, patient comfort, and ensuring that the removal process does not cause harm to the surrounding tissues. Given that this function is a routine procedure in orthodontic care, it aligns well with the responsibilities typically delegated to LDAs and hygienists.

In contrast, tasks like fitting orthodontic retainers and placing orthodontic bands may require more specific training or might fall outside of what is generally delegated to dental assistants under direct supervision, depending on state regulations. Performing tooth extractions is generally beyond the scope of practice for both LDAs and hygienists, as it involves significant surgical procedures that must be carried out by a licensed dentist or oral surgeon.
