Ethics in dentistry involves principles guiding professional conduct to ensure patient welfare respect and trust. Core principles include autonomy (respecting patient choices) beneficence (acting for patient's benefit) non-maleficence (avoiding harm) justice (fair treatment) and veracity (truthfulness). Dentists must maintain confidentiality obtain informed consent and provide competent evidence-based care. Ethical practice also involves honesty in professional relationships avoiding conflicts of interest and continuous learning. Upholding these values strengthens public trust and promotes high standards in dental care.
