Which of the following is NOT considered a remediable task without additional training?

Conducting diagnosis is the task that is not considered a remediable task without additional training. In the context of dental hygiene practice, diagnosis requires a deep understanding of dental pathology, patient assessment skills, and the ability to interpret clinical findings, which typically necessitates more extensive education and training than that provided in basic dental hygiene programs.

In contrast, the other tasks listed, such as providing fluoride rinse programs, instructing patients in oral hygiene care, and even removing calculus deposits under specific circumstances, can often be classified as remediable. These tasks can be performed by dental hygienists after completing initial training and may also be enhanced through additional training or continuing education, which allows practitioners to expand their skills without needing a complete re-education. Therefore, these tasks are considered within the realm of dental hygiene practice when proper training has been provided or when updates are applied within existing competencies.
