NBDHE Management of Special Needs Patients 3

Question 1

A patient with chronic kidney disease (CKD) on hemodialysis should receive dental hygiene treatment on which day relative to dialysis?

Accepted Answer

The day after dialysis (not on dialysis day)

Answer

Dental treatment is best scheduled the day after dialysis: the patient has had toxins removed, heparin anticoagulation has worn off (24-hour half-life), and the patient is not fatigued from the procedure.

Question 2

Patients taking phenytoin (Dilantin) for seizure control may develop which notable oral side effect?

Accepted Answer

Drug-influenced gingival enlargement (gingival overgrowth)

Answer

Phenytoin (Dilantin) is the classic cause of drug-influenced gingival enlargement, affecting up to 50% of patients; excellent oral hygiene minimizes its severity.

Question 3

An elderly patient with Alzheimer's disease presents with increased plaque accumulation and root caries. The MOST effective oral hygiene strategy involves:

Accepted Answer

Training and involving the caregiver in daily oral hygiene, using fluoride varnish applications, and simplified hygiene tools

Answer

As cognitive decline progresses, caregivers become essential partners; using high-fluoride applications, simplified tools (electric toothbrush), and caregiver training provides the most practical and effective oral care.

Question 4

A patient with a history of head and neck radiation therapy (≥60 Gy) presents for a hygiene appointment 2 years post-treatment. Which complication requires the most careful monitoring?

Accepted Answer

Osteoradionecrosis risk, severe xerostomia, radiation caries, and trismus

Answer

High-dose radiation to the head and neck causes permanent damage to salivary glands (xerostomia), vascular supply of bone (osteoradionecrosis risk), and masticatory muscles (trismus), with a lifelong risk of radiation caries.

Question 5

Which of the following best describes the American Heart Association's current recommendation regarding antibiotic prophylaxis before dental procedures for patients with prosthetic heart valves?

Accepted Answer

Prophylaxis is recommended before all dental procedures that involve manipulation of gingival tissue or the periapical region of teeth, or perforation of the oral mucosa

Answer

The 2007 AHA guidelines recommend antibiotic prophylaxis for high-risk cardiac conditions (prosthetic valves, previous endocarditis, congenital heart defects, cardiac transplant with valvulopathy) before gingival/periapical manipulation or mucosal perforation.
