Which is the fourth principle of the GDC?

• A. Have a clear complaints procedure
• B. Maintain and protect patient information
• C. Maintain, develop and work within your competence
• D. Put patients' interests first

Answer: (B)

Protecting patient information is a fundamental duty in dental care. This principle recognises that trust hinges on privacy: patients must feel confident that their personal details, treatment records, notes, and imaging are handled discreetly and kept secure. In practice, this means keeping accurate records, storing them securely (whether digital or paper), and ensuring access is limited to those involved in care or who have a legitimate, consented reason to see them. It also means sharing information only with proper consent or when there is a clear legal or professional justification, and handling data in a way that complies with data protection laws and guidance.

Understanding this standard helps explain its central role: without maintaining confidentiality, patients may withhold information or avoid treatment, which undermines care quality and safety. While having a clear complaints procedure or staying within one’s competence are important aspects of professional practice, the duty to protect patient information specifically underpins the integrity of the patient–clinician relationship and the ethical and legal framework governing care.
