Question 1
A patient with severe intellectual disability becomes highly
distressed during dental examinations. Previous attempts at
routine treatment have been unsuccessful. Which approach is
generally most appropriate as the initial management strategy?
A. Proceed immediately with general anesthesia
B. Use a patient-centered approach with gradual familiarization
and individualized behavioral support
C. Discontinue all dental care permanently
D. Use physical restraint for every appointment
Answer: B. Use a patient-centered approach with gradual
familiarization and individualized behavioral support
,Rationale: Patients with intellectual disability may require
additional time, communication adaptations, desensitization,
predictable routines, and environmental modification before
invasive treatment is considered. Gradual familiarization can
reduce anxiety and improve cooperation while preserving
dignity and autonomy. General anesthesia or restrictive
interventions may be appropriate in selected circumstances, but
they should not automatically replace less restrictive
approaches. Physical restraint should never be treated as a
routine first-line response.
Question 2
Which principle is most important when obtaining consent for
dental treatment from an adult patient who has a cognitive or
intellectual disability?
A. Assume the caregiver automatically has authority to consent
B. Exclude the patient from the discussion
C. Presume decision-making capacity is absent
D. Assess the individual's capacity for the specific decision and
support participation as much as possible
Answer: D. Assess the individual's capacity for the specific
decision and support participation as much as possible
,Rationale: Cognitive or intellectual disability does not by itself
establish lack of decision-making capacity. Capacity is generally
decision-specific and should be assessed according to applicable
law and professional requirements. Patients should receive
information in a form they can understand and be given
appropriate support to make their own decisions whenever
possible. A legally authorized representative may be involved
when the patient lacks the relevant capacity, but the patient's
preferences and participation remain important.
Question 3
A patient with Down syndrome presents for preventive dental
care. Which oral finding is particularly associated with Down
syndrome?
A. Markedly increased risk of amelogenesis imperfecta
B. Increased susceptibility to periodontal disease
C. Universal absence of permanent teeth
D. Complete absence of dental caries
Answer: B. Increased susceptibility to periodontal disease
Rationale: Individuals with Down syndrome have a well-
recognized increased susceptibility to periodontal disease.
Contributing factors can include altered immune response, oral
motor difficulties, plaque accumulation, anatomical
, characteristics, and challenges with maintaining effective oral
hygiene. Preventive periodontal care, individualized oral-
hygiene instruction, professional monitoring, and early
intervention are therefore especially important.
Question 4
A patient with cerebral palsy has significant involuntary
movements and difficulty maintaining a stable head position.
Which modification can improve safety during dental
treatment?
A. Ignore the movements and continue treatment normally
B. Use appropriate positioning and stabilization strategies
individualized to the patient
C. Increase the speed of treatment regardless of risk
D. Avoid all preventive treatment
Answer: B. Use appropriate positioning and stabilization
strategies individualized to the patient
Rationale: Positioning is particularly important for patients with
neuromuscular disorders. Appropriate support of the head,
trunk, and limbs can improve comfort, reduce uncontrolled
movement, facilitate airway protection, and improve access.
Positioning must be individualized and should not compromise
breathing or circulation. Preventive care remains essential even
