Which statement best describes the range of conditions that require antibiotic prophylaxis for dental procedures?

• A. All of the following: prosthetic heart valves or valve repair material; history of infective endocarditis; certain congenital heart defects; heart transplant recipients with valvular disease
• B. Only prosthetic heart valves
• C. Only history of infective endocarditis
• D. Only certain congenital heart defects

Answer: (A)

Bacteria from the mouth can enter the bloodstream during dental procedures and cause infective endocarditis in people who have certain heart conditions. Because of this, antibiotic prophylaxis is recommended for a range of high‑risk cardiac scenarios, not just one specific condition. The statement that includes prosthetic heart valves or valve repair material, a history of infective endocarditis, certain congenital heart defects, and heart transplant recipients with valvular disease best captures who may need prophylaxis. Each of these situations represents an elevated risk due to prosthetic material, prior infection, abnormal heart blood flow, or complex valvular disease. The other options are narrower and miss other high‑risk groups.
