Which of the following is a remediable task for a Dental Hygienist under general supervision?

The option regarding irrigating and evacuating debris is considered a remediable task under general supervision for a Dental Hygienist. General supervision allows dental hygienists to perform certain tasks without the direct supervision of a dentist, provided that the procedures are within the scope of their practice. Irrigating and evacuating debris typically falls within the hygienist's duties during a patient procedure, helping to maintain a clean working environment.

This task is also important in the context of dental hygiene because it helps facilitate other procedures, such as scaling or using ultrasonic instruments. The ability to perform this task without requiring direct oversight allows dental hygienists to operate efficiently while still adhering to safety and health regulations.

In contrast, obtaining endodontic cultures, placing temporary restorations with mechanical instruments, and conducting oral surgeries involve more complex procedures that go beyond the standard scope of practice for dental hygienists under general supervision. These tasks generally require direct supervision by a dentist due to their complexity and the potential risks involved.
