Under what circumstances can a hygienist replace a periodontal dressing?

A hygienist can replace a periodontal dressing when the dentist of record cannot pre-examine the patient. This provision allows hygienists to perform specific functions that are necessary for patient care, especially in situations where access to the dentist is not feasible. The regulation acknowledges the hygienist's training and responsibility to provide care in the interest of patient continuity and wellbeing.

This situation is particularly relevant in busy clinical environments where the dentist may be attending to other patients or unforeseen circumstances that prevent them from performing a pre-examination. The hygienist’s ability to proceed with the dressing change helps ensure that the patient's treatment is not delayed, facilitating better outcomes in periodontal care.

In contrast, replacing the dressing solely based on the patient's request does not align with the professional and regulatory standards guiding dental practice. Similarly, requiring a pre-examination by the dentist for every dressing change could unnecessarily impede timely treatment. The option suggesting that hygienists cannot replace the dressing at all disregards their competencies and the relevant legal framework that allows them to perform certain duties when specific criteria are met.
