A dentist fully and honestly explains a treatment error to the patient. This action most directly upholds which ethical principle?

Veracity is the duty to be truthful and not deceive. Honestly disclosing information, including mistakes, to the patient reflects veracity.Other options: Justice = fairness in the distribution of care; beneficence = acting for the patient's good; autonomy = respecting the patient's right to self-determination (informed consent supports autonomy, but the honesty itself is veracity).Key exam takeaway: Veracity = truth-telling; it underlies honest disclosure and informed consent.
