Written consent is usually required for which type of procedure?

• A. For routine cleaning
• B. For brief examinations
• C. For invasive or complex procedures
• D. For consent to use personal data

Answer: (C)

Written consent is usually required for invasive or complex procedures because these carry higher risk, more potential for complications, and longer-term or irreversible consequences. Documenting that the patient has been fully informed about what will be done, the alternatives, the possible risks and benefits, and the expected outcomes helps ensure the patient truly understands and agrees to the treatment. It also provides a clear legal record that protects both the patient’s autonomy and the clinician.

For routine cleaning or brief examinations, consent is often verbal or implied through the patient’s cooperation, since these are low-risk and straightforward. Consent to use personal data relates to privacy and data protection, not to the clinical procedure itself.
