Question 3

When applying fluoride varnish in a clinical setting, the clinician should instruct the patient to:

Accepted Answer

Avoid eating hard foods, hot beverages, and brushing for at least 4–6 hours after application

Answer

After fluoride varnish application, patients should avoid hard/crunchy foods, hot drinks, and brushing for 4–6 hours to maximize fluoride uptake into enamel while the varnish remains on tooth surfaces.

Question 4

Which type of stroke is used during the assessment phase of ultrasonic debridement to detect calculus?

Accepted Answer

Light, overlapping exploratory strokes with the tip parallel to the tooth surface

Answer

Ultrasonic assessment uses light, overlapping strokes with the side/tip of the instrument kept nearly parallel to the tooth to detect calculus by tactile feedback without excessive thermal/mechanical trauma.

Question 5

A patient with xerostomia secondary to Sjögren's syndrome should receive which dental hygiene intervention to prevent root caries?

Accepted Answer

Prescription-strength 1.1% sodium fluoride (5,000 ppm) toothpaste applied daily and fluoride varnish every 3 months

Answer

Sjögren's syndrome causes severe xerostomia with dramatically elevated caries risk; prescription 5,000 ppm fluoride toothpaste (daily) combined with quarterly in-office fluoride varnish provides maximum caries protection.
