Who is allowed to place and remove rubber dams or other isolation devices?

The correct answer is that all of the options listed are allowed to place and remove rubber dams or other isolation devices. In California, the Dental Practice Act clearly defines the roles and permitted functions of dental auxiliary personnel, including dental assistants, registered dental assistants, and registered dental assistants with extended functions.

A dental assistant can assist with basic procedures, which often includes the use of rubber dams or similar isolation devices under the supervision of a licensed dentist. A registered dental assistant possesses additional training and qualifications, allowing them to perform more advanced tasks, including placing and removing these devices in a clinical setting.

The registered dental assistant with extended functions has even further qualifications, enabling them to perform a wider array of dental procedures, but their ability to place and remove isolation devices aligns with the general permissions granted to dental professionals at various levels. Thus, all these roles are legally permitted to handle and utilize rubber dams and other isolation materials in their practice. This reflects not only the structured hierarchy in dental practice but also ensures patient safety and adherence to legislative standards.
