⩥ 41-yo woman, pregnant; prev rheumatic fever with heart murmur (no
valvular abnormality); allergy to penicillin. Positive history of infective
endocarditis. Does she need to pre med?
- yes
- no. Answer: yes
- REVIEW HEALTH HISTORY - on my exam, this patient had a
previous history of infective endocarditis. Pre-med IS indicated
- many of the OSCE quizlets say no....
⩥ Pre-med options for pregnant woman w/hx of infective endocarditis
and penicillin allergy
- amoxicillin
- cephalexin
- clarithromycin
- ciproflaxacin. Answer: *clarithromycin*
I may not be correct, the correct option may be cephalexin. however I
chose clarithromycin due to penicillin allergy, cross reaction with
cephalosporins, and since clindamycin/erythromycin/azthromycin were
,not options. Ciproflaxacin is contraindicated in pregnancy. article for

⩥ What procedure can a dentist perform without consulting MD if a
patient is currently taking bisphosphonates?
- endo therapy
- prophy and scaling
- extraction
- occlusal restoration. Answer: *occlusal restoration*
although the main HELL NO is extraction, completing endo therapy
increases risk if the apex is compromised/damaged during therapy. I
teetered on prophy and scaling, but since it did not specify
supragingival, decided that the risk of scaling can negatively affect the
periosteum of a bisphosphanate patient. ADA recommendations:
