Previous episode of infective endocarditis B. Patients that have had a coronary artery bypass graft (CABG) C. Patients with a pacemaker D. None of the above conditions are considered associated with the highest risk of adverse outcome from endocarditis and therefore antibiotic prophylaxis with dental procedures not needed 4.

Doxycycline 100 mg by mouth 30 - 60 minutes prior to dental procedure, if the patient is penicillin allergic. b. Amoxicillin 2 grams by mouth 30 – 60 minutes prior to dental procedure. c.

It is appropriate for the dentist to make the final judgment to use antibiotic prophylaxis for patients potentially at higher risk of experiencing prosthetic joint infection (independent of dental treatment) using the AUC as a guide, without consulting the orthopedic surgeon d. The AUC is supported by a strong base of scientific evidence 8. The clinical practice guideline recommendations in: The use of prophylactic antibiotics prior to dental procedures in patients with prosthetic joints: Evidence-based clinical practice guideline for dental practitioners.

The above statement is: a. True b. False 9. Please choose the correct statement: a. The benefits of using antibiotics ALWAYS outweighs the risks B. There is evidence that antibiotics taken before dental procedures PREVENT prosthetic joint infections C.
