What is a requirement for dental practices under GDPR?

The requirement for dental practices under GDPR emphasizes the importance of data protection and the ethical handling of personal information. The correct response focuses on the responsibility of dental practices to dispose of personal information properly. This means that practices must ensure that any patient data that is no longer necessary for the purpose for which it was collected is securely destroyed or anonymized. This protective measure helps maintain patient confidentiality and aligns with data minimization principles, which are key tenets of GDPR legislation.

In contrast to this, the other options promote actions that directly conflict with the regulations established by GDPR. Publicly disclosing all patient information would violate privacy rights and confidentiality agreements. Collecting excessive data without a purpose contravenes the principle of data minimization that GDPR enforces, essentially indicating that data should only be collected when necessary. Lastly, using personal data for marketing without consent undermines the crucial requirement of obtaining explicit permission from individuals before processing their personal information for marketing purposes. This underscores the necessity of consent in maintaining trust and compliance with GDPR standards.
