For orthopaedic prosthesis patients undergoing dental procedures, is antibiotic prophylaxis recommended?

• A. No prophylaxis is required
• B. Yes, 2 g amoxicillin 60 minutes before dental appointment
• C. Use topical antiseptic rinse only
• D. Give azithromycin 500 mg instead

Answer: (B)

Bacteremia from dental procedures can seed a prosthetic joint, and infections of an artificial joint can be serious and hard to treat. To reduce this risk in patients with orthopedic prostheses, preventive antibiotics are given before procedures that involve manipulation of the gums, periapical region, or oral mucosa. The strongest, most widely used regimen is amoxicillin 2 g taken orally about 60 minutes before the dental appointment, ensuring adequate drug levels at the time of potential bacteremia. If penicillin cannot be used, alternative options include clindamycin 600 mg or azithromycin/clarithromycin 500 mg. Using a topical antiseptic rinse alone does not prevent bacteremia, and opting for no prophylaxis would miss the preventive protection these guidelines aim to provide.
