Final answer:
Infection control during dental treatment is an example of the principle of nonmaleficence, which aims to prevent harm to patients.
Step-by-step explanation:
Providing patients with infection control during dental treatment exemplifies the principle of nonmaleficence. This ethical principle dictates that healthcare providers should act in ways that do not cause harm to others. In dental practice, infection control is vital to ensure that patients are not exposed to unnecessary harm, such as the transmission of infectious diseases.
The principle of beneficence is related but distinct, as it involves taking actions that benefit patients, beyond simply avoiding harm. This might include procedures or interventions that are intended to improve the patient's condition, rather than just maintaining their current health status.
The correct answer to the student's question is: Nonmaleficence.
