DENTAL OSCE QUESTIONS AND DETAILED
ANSWERS
Immunosuppresant drug used in Transplant Patients that causes Gingival
HyperplasiaANSWER>> Cyclosporine
How is Perio disease related to diabetes?ANSWER>> Glucose levels are increased.
Cause for cement failure?ANSWER>> increased SOLUBILITY of the cement
Before trimming teeth on a stone cast for an immediate denture, you must
first...ANSWER>> mark a line 3 mm above the free gingival margin.
** Which analgesic(s) is safe for a Patient with kidney disease?ANSWER>> Tylenol
(acetaminophen) ONLY.
NOT NSAIDS OR ASPIRIN
** For Patients on dialysis, where do you take their blood pressure?ANSWER>> On the

How do you prevent syncope?ANSWER>> Trendlenburg position.
(feet higher than head)
How do you treat syncope if breathing?
How do you treat syncope if not breathing?ANSWER>> Place the patient in the
trendlenburg position. (flat/feet higher than head)
If breathing? Use crushed ammonia under nose and pure oxygen.
,Not breathing? start BLS.
Treatment of a child with Fibrous Dysplasia?ANSWER>> for kids, prolong surgical
intervention as long as possible.
some lesions will stabilize & some lesions will grown. Only surgically remove if esthetics

tissue develops in place of normal bone. This can weaken the affected bone & cause
deformations or fractures.
*Radiographic appearance: orange peel if late stage.
** Treatment of barbiturate allergic reaction.ANSWER>> antihistamine (synergic
reaction to barbituate) ** look at this.
**Can you treat a patient who had Hepatitis A, one year ago?ANSWER>> yes. they can
be treated "1 week after having jaundice" -- the exam referred to it as jaundice.
At what intervals are intermediate dentures evaluated?ANSWER>> 24- hrs.

decreased swelling of the gingiva.

"a reverse exposure of x-ray film"
film that requires least amount of radiation?ANSWER>> e-speed.
