As an LDA, when can you remove calculus from a patient?

Removing calculus from a patient is generally accepted to be appropriate as long as it is above the gum line. This practice aligns with the guidelines for dental hygienists and other qualified professionals who are trained to address supragingival calculus—calculus that forms above the gum line and is often more accessible during routine cleanings and check-ups.

Supragingival calculus removal is a fundamental part of dental hygiene practice, as it helps to prevent further periodontal disease and oral health issues. The removal of calculus below the gum line, or subgingival calculus, is more complex and typically requires a dentist or a hygienist with advanced training and specific protocols for treatment.

In this context, the other options are not aligned with standard practices. For example, the option regarding removal only during emergencies does not reflect regular dental cleaning procedures where calculus can be addressed proactively. The reference to needing a dentist's instruction to remove calculus might imply that hygienists lack autonomy in performing their duties, which is not the case for above-gum-line calculus. Thus, the correct choice highlights the standard scope of practice for removing calculus while ensuring patient safety and effective care.
