What do the ethical principles of nonmaleficence and beneficence signify?

The correct choice accurately reflects the definitions of the ethical principles of nonmaleficence and beneficence. Nonmaleficence, which translates to "do no harm," is a fundamental principle in healthcare ethics that emphasizes the importance of avoiding any actions that could cause harm to patients. This principle obligates dental hygienists and other healthcare professionals to refrain from treatments that may pose unnecessary risks to patients’ health or well-being.

Beneficence, on the other hand, refers to the obligation to promote good and to act in the best interests of the patient. This principle encourages dental professionals to provide care that benefits patients, supporting their health and well-being through appropriate treatments and interventions.

Together, these principles are foundational in guiding ethical decision-making in dental hygiene practice, ensuring that patient safety and welfare are prioritized. Understanding these concepts is critical for RDHs as they strive to deliver quality dental care and uphold professional ethics in their practice.
