What are the ADA recommendations for when pre-med is required
- prosthetic 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 conduits
--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

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
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
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 reference https://www.parents.com/pregnancy/my-body/is-it-
safe/antibiotics-and-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
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:

%20Treatment%20of%20Patients%20on%20Bisphosphon.pdf
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
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
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
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
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
barbituates
- used primarily evening BEFORE appointment
A patient has an allergic reaction to a barbiturate, how do you treat?
- epinephrine
- diphenhydramine
- send to ER
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
A patient is on a steroidal medication. What information do you need to obtain
before treating them?
- dose and pharmacy that filled the RX
- duration of prescription
- both dose and duration
dose and duration
- "The rule of twos": Ask whether the patient is currently on steroids or has been on
corticosteroids for 2 weeks or longer within the past 2 years. You must go back 2 years
in the history because it can take 2 weeks to 2 years for the adrenal glands to bounce
back to normal function.
What is the most important factor when calculation medication dosage for a child
- age
- weight
- gender
- height
weight
A patient is confirmed to have trisomy 21. What are you initially concerned
about?
- congenital heart defect
- Cushings
- cerebrovascular accident
congenital heart defects; however, early onset periodontal disease is a significant oral
health issue, but this was not an answer for those who have had this question. Consider
cardiac status and posibility of pre-medication
- atrioventricular septal defect, patent ductus arteriosus, Tetralogy of Fallot
A patient has recently had a stroke. What is your first concern?
- when was their last cleaning
- are they on anticoagulants
- current blood pressure
Are they on anticoagulants
- Stroke patients could be on blood thinners, such as aspirin, dipyradamole (Persan-
tine), clopidogrol (Plavix), or Coumadin, postrecovery. Prior to major surgery, always
consult with the patient's physician to determine whether and when the blood thinners
