VERSION
Which of the following factors would contribute to the likelihood of a patient having OSA?
A. Reduced ventilatory response during an apneic arousal (low loop gain)
B. Increased upper airway dilator muscle responsiveness
C. Increased arousal threshold
D. Increased upper airway surface tension - answer>>>D. Increased upper airway surface
tension
The underlying pathophysiology of OSA is multifactorial and varies considerably between
individuals. Which of the following would be a reasonable targeted therapy?
A. Sedatives for individuals with low arousal thresholds
B. Supplemental oxygen for individuals with low loop gain
C. Sedatives for individuals with high arousal thresholds
D. Supplemental oxygen for individuals with stable ventilatory control - answer>>>A.
Sedatives for individuals with low arousal thresholds
A new patient presents with a class III anterior bite that she believes was caused by use of
an oral appliance for her moderately severe OSA. She explains that she is CPAP intolerant.
You should immediately:
A. Refer the patient to an orthodontist
B. Advise the patient to discontinue her use of OAT
C. Ask the name of her treating DSM provider so you can make a complaint to the state
dental association
, -
D. Gather subjective and objective data until you have enough information to consider an
assessment and plan - answer>>>D. Gather subjective and objective data until you have
enough information to consider an assessment and plan
A patient that you are treating for OSA with OAT presents to your office complaining that
her upper and lower back teeth no longer touch when she tries to bite them together. She
reports that she can only feel her front teeth touching. After examination, you conclude
that this is related to contracture of her lateral pterygoid muscles bilaterally with
resultant forward posturing of the mandible. Which of the following will best determine
how successful you'll be in helping her re-establishment of her original occlusion?
A. Degree of original overbite
B. Length of time her muscles have been in contracture
C. Degree of original overjet
D. Class of dental occlusion at the start of treatment - answer>>>B. Length of time her
muscles have been in contracture
In response to the Epworth Sleepiness Scale, your patient reports they have a very high
chance of dozing when laying down to rest in the afternoon when circumstances permit,
but no other circumstance when they would doze. Out of a possible 24, your patient's
score would be:
A. 1
B. 2
C. 3
D. 4 - answer>>>C. 3
During a clinical examination, you note that your patient has missing 3rd molars and short
clinical crowns #18, #19, #30, and #31. These teeth are conically shaped and present a
,retention concern. When you consider the propulsion mechanism of your device, you may
want to AVOID selecting:
A. Attached: Bilateral Compression
B: Attached: Anterior Traction
C: Attached: Bilateral Traction
D: Unattached: Bilateral Interlocking - answer>>>C: Attached: Bilateral Traction
Accreditation of a facility represents that the DSM services provided exemplify all of the
following except:
A. Proficiency
D. Productivity
C. Professionalism
D. Proper protocol - answer>>>D. Productivity
Which of the following is NOT part of AADSM standard protocol for long term OAT care:
A. Evaluation for dental side effects
B. Recording vitals
C. Assessment of subjective symptoms
D. Assessment with objective home sleep testing - answer>>>D. Assessment with
objective home sleep testing
Common dental side effects with long term use of an oral appliance include:
A. Change in occlusal contacts
B. Mesial tipping of maxillary and mandibular molars
C. Increase in overbite and overjet
D. Generalized tooth mobility - answer>>>A. Change in occlusal contacts
Regarding long term compliance to OAT (5 years), Marklund found that:
, -
A. Overbite decreases continually but overjet changes wane
B. 90% of patients showed compliance at 5 years
C. Overjet decreases continually but overbite changes wane
D. Only 15% of patients abandoned OAT - answer>>>C. Overjet decreases continually but
overbite changes wane
The relationship between mandibular advancement and the forces created by the MAD as
described by Cohen-Levy is:
A. Linearly related
B. Geometrically related
C. Inversely related
D. Arithmetically related - answer>>>A. Linearly related
Which of the following cephalometric predictors is most likely to correlate to MAS
success:
A. High mandibular plane angle
B. Reduced distance to hyoid bone and mandibular inferior border
C. Longer soft palate
D. Shorter anterior face height - answer>>>B. Reduced distance to hyoid bone and
mandibular inferior border
(Retrognathic mandible)
The dental explanation for occlusal contact changes while wearing an oral appliance for
SRBD includes all of the following except:
