Regarding dental prophylaxis for patients with a knee or hip replacement, which statement is supported by the material?

• A. Antibiotics are required for all dental procedures at all times.
• B. Antibiotics are recommended only for high-risk patients before dental procedures.
• C. There are no recommendations for antibiotic prophylaxis 6 months after surgery.
• D. Antibiotics should be given routinely every year before dental procedures.

Answer: (C)

Prophylactic antibiotics before dental work in patients with knee or hip replacements are not routinely indicated. The risk of a dental procedure causing infection in a prosthetic joint is low, so guidelines no longer support giving antibiotics for every procedure. The statement about having no recommendations for antibiotic prophylaxis six months after surgery reflects that, once the early postoperative period has passed, there isn’t a standing rule to provide antibiotics just because dental work is planned. In practice, antibiotics may be considered only for very high‑risk individuals on a case-by-case basis, not as a blanket yearly or universal protocol.
