After the dentist explains the diagnosis and all treatment options, and the patient understands and verbally agrees, the next step / type of consent is:

Correct answer: B. Informed consent

• A. Incorrect – informed consent should be documented.
• B. Correct – disclosure of diagnosis, options, risks, benefits and alternatives, with the patient's understanding and agreement, constitutes informed consent (document/sign).
• C. Incorrect. Coerced consent is not valid consent; once the informed patient voluntarily agrees, valid informed consent is obtained.
• D. Incorrect – implied consent is inferred from actions (e.g., sitting in the chair), without a full discussion.
