Which of the following is NOT true about a dental hygienist with a temporary endorsement?

A dental hygienist with a temporary endorsement is typically limited in the scope of practice when compared to a fully licensed hygienist. While they can perform certain functions such as administering local anesthetic injections or nitrous oxide/oxygen analgesia under specific circumstances, they do not have the same level of authority when it comes to more invasive procedures.

Placing restorations in cavities involves a higher level of clinical skill and is generally restricted to dentists or fully licensed dental hygienists who have completed special training and have full credentials. Therefore, stating that a dental hygienist with a temporary endorsement can place restorations is not true.

In contrast, performing injections of local anesthetic and administering nitrous oxide/oxygen analgesia are often within the capabilities allowed during the temporary period, as long as they have received the necessary training and comply with specific guidelines. Additionally, soft tissue curettage may also be permitted, reflecting a more limited clinical responsibility.
