Mandatory reporting of child abuse by a dentist falls under which ethical principle?

Mandatory reporting of child abuse by a dentist is an act of beneficence — acting in the best interest of the vulnerable child by taking positive action to protect them from harm. Beneficence requires not just avoiding harm but actively promoting the welfare of patients. Reporting suspected abuse ensures the child receives protection and appropriate intervention. Justice is also relevant (treating all patients fairly and protecting vulnerable populations), but the primary ethical driver is beneficence. Non-maleficence covers 'do no harm' (passive avoidance of harm). Mandatory reporting is a proactive, positive obligation — the hallmark of beneficence.
