In which procedure can a dental hygienist directly place and remove matrix bands?

A dental hygienist can directly place and remove matrix bands under direct supervision of a dentist. This level of supervision means that the dentist is physically present in the office and is available to provide guidance and immediate assistance if necessary. The procedure of placing and removing matrix bands is a technical task that requires the hygienist to follow specific protocols to ensure patient safety and the success of the dental procedure.

Direct supervision is crucial in this context because matrix bands are often used during restorative procedures to aid in the shaping of a filling material, which necessitates the expertise and oversight of the dentist. The dentist's presence ensures that the hygienist can perform the task effectively while still having access to the dentist’s professional judgment in real time.

While indirect supervision could allow for certain tasks to be completed by the hygienist, placement and removal of matrix bands typically requires the direct oversight of the dentist due to its more complex nature. Procedures without supervision are generally restricted to tasks that are less invasive or do not require a high level of skill that must be monitored. The statement about assisting with orthodontics refers specifically to a narrower scope of practice and does not encompass the broader role of matrix band usage, which applies primarily to restorative dentistry.
