thetic cardiac valves, including transcatheter-implanted prostheses and homografts
- prosthetic material used for cardiac valve repair, such as annuloplasty rings and
chords
- a history of infective endocarditis
- a cardiac transplanta with valve regurgitation due to a structurally abnormal valve
- the following congenital (present from birth) heart disease
--unrepaired cyanotic congenital heart disease, including palliative shunts and con-
duits
--any repaired congenital heart defect with residual shunts or valvular regurgitation
at the site of or adjacent to the site of a prosthetic patch or a prosthetic device

2. 41-yo woman, pregnant; prev rheumatic fever with heart murmur (no valvu- lar
abnormality); allergy to penicillin. Positive history of infective endocarditis. Does she
need to pre med?
- yes
- no: 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....
3. Pre-med options for pregnant woman w/hx of infective endocarditis and
penicillin allergy
- amoxicillin
- cephalexin
- clarithromycin
- ciproflaxacin: *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 con-
traindicated in pregnancy. article for reference https://www.parents.com/pregnan-
cy/my-body/is-it-safe/antibiotics-and-pregnancy/
4. What procedure can a dentist perform without consulting MD if a patient is
currently taking bisphosphonates?
- endo therapy
- prophy and scaling
- extraction
- occlusal restoration: *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 nega-
tively affect the periosteum of a bisphosphanate patient. ADA recommendations:

tions%20for%20Treatment%20of%20Patients%20on%20Bisphosphon.pdf
5. Pregnant person afraid of needles - stress management by putting patient in
what position when in your chair (BEFORE they even get to the point of passing
out)?
- supply oxygen
- place in Trendelenburg
- make patient sit up straight
- turn the patient, preferably to the left side: turn the patient, preferably to the left
side
- Best preventative treatment for supine hypotension is to turn the patient, preferably
to the left side, to displace the uterus away from the inferior vena cava. The patient
can also be placed in a sitting position with the knees flexed.
6. 6 months pregnant had bleeding gums and mobile teeth, how should they be
treated?
- immediate extractions
- do not treat until baby is born
- conservative debridement
- immediate endo: conservative debridement
.- pregnancy gingivitis: important to do ScRP (and stress good oral hygiene) to
, prevent plaque growth. The plaque can enter blood stream and stimulate patient's
immune system to produce prostaglandins, which can trigger uterine contraction
leading to early labor, premature birth, and a small baby.
7. Pregnant lady with a diastema in between #8 and #9 with deep probing depth and
class 1 mobility on 8 and 9. What is the reason for diastema?
- chronic periodontitis
- distal drift
- normal during pregnancy: chronic perio
- increased incidence of periodontal disease during pregnancy => must emphasize
good oral hygiene, and remove all their plaque so it doesn't lead to premature birth
/ low birth weight
8. Permanent staining as a result of tetracyline; did this happen?
- During development (as fetus)
- 0-5yrs
- 5-10 yrs
