Question 1
A patient receiving intensive chemotherapy is scheduled for a
comprehensive dental evaluation. Which factor is most
important when determining the timing of invasive dental
treatment?
A. The patient's age
B. The patient's preferred appointment time
C. The patient's current blood counts and anticipated
chemotherapy schedule
D. Whether the patient has dental insurance
Answer: C. The patient's current blood counts and anticipated
chemotherapy schedule
,Rationale: Chemotherapy can produce neutropenia and
thrombocytopenia, substantially changing the patient's risk of
infection and bleeding. Dental treatment should therefore be
coordinated with the oncology team and timed according to the
patient's hematologic status and treatment cycle. Planning
before chemotherapy begins is often preferable because existing
oral disease can be stabilized before the period of greatest
immunosuppression. Age, appointment preference, and
insurance status do not determine the biological safety of
invasive treatment.
Question 2
Which oral complication is particularly associated with head-
and-neck radiation therapy?
A. Increased salivary flow
B. Xerostomia and increased risk of dental caries
C. Permanent reduction in oral bacteria
D. Decreased risk of periodontal disease
Answer: B. Xerostomia and increased risk of dental caries
Rationale: Radiation involving the salivary glands can
substantially reduce salivary function. Saliva normally lubricates
tissues, buffers acids, supports remineralization, and helps
control microorganisms. Reduced salivary flow therefore
,increases the risk of xerostomia, difficulty swallowing, mucosal
discomfort, and rapidly progressing dental caries. Radiation can
also produce long-term changes in oral tissues and bone. It does
not increase salivary flow or protect against oral disease.
Question 3
A patient with severe neutropenia develops fever and a painful
oral ulcer. What is the most appropriate dental management?
A. Perform elective periodontal surgery immediately
B. Delay communication with the medical team until the next
dental visit
C. Promptly communicate with the patient's medical/oncology
team because infection may become serious rapidly
D. Treat the lesion only with an abrasive oral rinse
Answer: C. Promptly communicate with the patient's
medical/oncology team because infection may become
serious rapidly
Rationale: Neutropenia reduces the body's ability to contain
bacterial and fungal infections. A mucosal ulcer can become a
portal of entry for microorganisms, and infection in a severely
immunocompromised patient may progress rapidly to systemic
infection. Fever in a significantly neutropenic patient is a
medical concern rather than a routine dental problem. Elective
, invasive treatment should not be undertaken without
appropriate medical coordination.
Question 4
Which oral finding is strongly associated with
immunosuppression in patients with HIV infection?
A. Physiologic gingival pigmentation
B. Geographic tongue alone
C. Oral candidiasis
D. Enamel hypoplasia caused by childhood illness
Answer: C. Oral candidiasis
Rationale: Oral candidiasis is a common opportunistic infection
associated with impaired immune function, including HIV
infection. It may present as removable white plaques,
erythematous lesions, or other patterns depending on the
clinical form. Its presence can provide useful information about
immune status and should prompt appropriate clinical
assessment. The other findings are not characteristic markers of
HIV-associated immunosuppression.
