What prophylaxis is required for a patient with a history of deep vein thrombosis?
Show answer and explanation
Correct answer: B. None — DVT is not an indication for antibiotic prophylaxis
- A. The dentist does not initiate anticoagulation; the physician manages any perioperative bridging.
- B. Correct. DVT carries no endocarditis risk and requires no antibiotic prophylaxis. The relevant dental concern is bleeding risk from the patient's anticoagulant therapy, not infection.
- C. Antibiotic prophylaxis is reserved for the specific AHA cardiac categories — DVT is not among them.
- D. Same reasoning — no antibiotic indication exists.
