,SECTION 1: ORAL APPLIANCE THERAPY PROTOCOLS AND FOLLOW-UP
1. Standard AADSMP protocol for post-delivery follow-up of the oral appliance involves:
1) A phone call within two weeks of delivery to the patient
2) An office visit within two weeks of delivery
3) An office visit within one month of delivery
4) A HSAT or pulse oximetry recording acquired within 90 days
Correct Answer: 3
Rationale: The American Academy of Dental Sleep Medicine Protocol (AADSMP) mandates an in-office
follow-up visit within one month of appliance delivery to assess fit, comfort, side effects, and initial
efficacy. This timeline allows for early adjustments before complications escalate, ensuring patient
compliance and safety. While phone calls and HSAT are important later, the one-month visit is the
standard for direct clinical evaluation.
2. A patient with OSA on OAT reports progressive difficulty opening his mouth fully in the morning. This
symptom typically resolves within:
1) Minutes to hours
2) 1-2 days
3) 1-2 weeks
4) It is permanent
Correct Answer: 1
Rationale: Morning temporomandibular joint (TMJ) stiffness or muscle trismus is a common transient
side effect of oral appliance therapy. This occurs due to prolonged mandibular protrusion during sleep,
leading to muscle fatigue. The symptom is typically benign and resolves within minutes to a few hours
after waking as the masticatory muscles relax and return to resting position.
3. Which of the following is the most appropriate management for a patient with OSA who develops
significant dental mobility while using an OAT?
1) Reduce advancement
2) Add a periodontal splint
[2]
,3) Discontinue OAT and consider alternative therapy
4) Increase vertical dimension to reduce forces
Correct Answer: 3
Rationale: Significant dental mobility indicates advanced periodontal compromise or excessive occlusal
forces that threaten tooth viability. Reducing advancement or adding splints may mask the problem but
does not address the root cause. Discontinuation is the safest option to prevent tooth loss, and
alternative therapies like CPAP or positional therapy should be considered.
4. Which of the following is the most common complication of long-term CPAP use?
1) Aerophagia
2) Central apnea
3) Pneumothorax
4) Chronic rhinitis
Correct Answer: 1
Rationale: Aerophagia, or the swallowing of air, is the most common long-term complication of CPAP
therapy, affecting up to 50% of users. It results from positive airway pressure forcing air into the
esophagus and stomach, leading to bloating, belching, and abdominal discomfort. While chronic rhinitis
and mask leaks are frequent, aerophagia is the most prevalent persistent issue.
5. Which of the following is the most common cause of OAT failure in the first year of use?
1) Ineffective reduction of AHI
2) Side effects such as TMJ pain or tooth discomfort
3) Cost of the device
4) Lack of improvement in sleepiness
Correct Answer: 2
Rationale: Side effects, particularly TMJ pain, dental discomfort, and excessive salivation, are the leading
causes of oral appliance therapy discontinuation within the first year. Even when appliances are
clinically effective in reducing AHI, patient intolerance due to discomfort frequently leads to
abandonment of therapy.
6. Which of the following is the most appropriate next step when a patient with OSA on OAT has a
repeat sleep study showing an AHI of 18 (baseline 25)?
[3]
, 1) Accept the result as clinically successful
2) Advance the mandible further and repeat testing
3) Add CPAP combination therapy
4) Switch to a different OAT device
Correct Answer: 2
Rationale: An AHI of 18 represents a partial response (approximately 30% reduction from baseline) but
does not meet the standard success criteria of AHI <5 or <10 with symptom improvement. Further
mandibular advancement is the logical next step to increase airway patency, followed by repeat testing
to confirm efficacy before considering combination therapy.
7. Which of the following is the most important factor when deciding between CPAP and OAT for a
patient with mild-to-moderate OSA?
1) Patient preference and adherence likelihood
2) Baseline AHI
3) Oxygen nadir
4) Severity of snoring
Correct Answer: 1
Rationale: In mild-to-moderate OSA, both CPAP and OAT are viable options with comparable efficacy.
Patient preference is the dominant factor because adherence is the primary determinant of long-term
success. A patient who prefers and is motivated to use a specific device will have better outcomes than
one forced into a therapy they dislike.
8. Which of the following is the most appropriate treatment for a patient with OSA and poorly
controlled asthma?
1) OAT alone
2) CPAP with heated humidification
3) Leukotriene receptor antagonist alone
4) Nasal surgery
Correct Answer: 2
Rationale: CPAP with heated humidification is the preferred treatment because it addresses both OSA
and the asthmatic airway. Heated humidification prevents airway drying and irritation, reducing asthma
exacerbations triggered by cold or dry air. OAT does not address the lower airway, and surgery alone is
insufficient for OSA management in this context.
