Which of the following represents a key ethical principle for dental hygienists?

The principle of confidentiality of patient information is fundamental to the dental hygienist's ethical practice. This concept is rooted in the importance of trust in the patient-provider relationship. Patients must feel secure that their personal health information is protected and will not be disclosed without their consent. This protection aligns with both legal obligations, such as HIPAA regulations, and ethical standards that prioritize respecting patients' rights and dignity.

Maintaining confidentiality fosters an environment where patients are more likely to share sensitive information, allowing for more accurate assessments and better overall care. Ethical practice also entails being vigilant in safeguarding patient records and discussing sensitive information only in appropriate settings. Therefore, upholding confidentiality is not just a legal requirement, but also a cornerstone of ethical practice in healthcare, including dental hygiene.
