DSE-OSCE STUDY GUIDE ACTUAL EXAM EXAM
Q&A 2026 100% CORRECT.
⫸ 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.

,⫸ 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:

⫸ 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
- tell them to suck it up buttercup. Answer: place her in Trendelburg
position.
- supine hypotension in 3rd trimester usually occurs (bc compression
Inf vena cava) => must prevent this in dental chair bc it can cause
patient to pass out.
,- 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 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. Answer: 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.
⫸ 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. Answer: 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
, ⫸ Permanent staining as a result of tetracyline; did this happen?
- During development (as fetus)
- 0-5yrs
- 5-10 yrs
- 10-15 yrs. Answer: age 0-5 years
- remember that PERMANENT dentition does not begin calcification
until birth
⫸ Pentobarbital (Nembutal) and Secobarbital (Seconal) are what
type of drugs?
- benzodiazepines
- NSAIDS
- barbituates
- atypical antipsychotic. Answer: barbituates
- used primarily evening BEFORE appointment
⫸ A patient has an allergic reaction to a barbiturate, how do you
treat?
- epinephrine
- diphenhydramine
- send to ER. Answer: benadryl (diphenhydramine)
- And discontinuation of the drug. Obviously if there are concerns
with airway, treatment may differ... but this was not indicated in the
question stem. However, I did not have answer choices that reflected
this scenario nor was it addressed in the question stem
