1. Under Florida law, which of the following tasks is considered a remediable task
for a dental assistant with expanded functions training?
,A. Final vertical dimension for a denture
B. Placing and removing rubber dams
C. Performing a pulpotomy
D. Adjusting permanent crowns intraorally
🟢 B. Placing and removing rubber dams
🔴 RATIONALE: Florida Statutes define remediable tasks as those which are
reversible and do not create unalterable changes. Placing rubber dams is a standard
expanded function, whereas pulpotomies and final vertical dimensions are non-
remediable.
2. When polishing clinical crowns, what is the primary reason for using a slow-
speed handpiece with light pressure?
A. To prevent damage to the enamel or pulp overheating
B. To ensure the prophy paste adheres to the tooth
C. To reduce the time required for the procedure
D. To allow the patient to remain still
🟢 A. To prevent damage to the enamel or pulp overheating
🔴 RATIONALE: High speeds or heavy pressure during coronal polishing can
generate frictional heat, which may damage the dental pulp or abrade the enamel.
, 3. A patient presents with a history of Hepatitis B. According to Standard
Precautions, how should the dental assistant proceed with sterilization of the
instruments used?
A. Double-cycle the instruments in the autoclave
B. Soak instruments in high-level disinfectant for 24 hours
C. Follow the same heat-sterilization protocols used for all patients
D. Use disposable instruments only and discard them in biohazard
🟢 C. Follow the same heat-sterilization protocols used for all patients
🔴 RATIONALE: Standard Precautions dictate that all patients are treated as
potentially infectious; standard sterilization protocols (autoclave) are sufficient to kill
HBV.
4. Which of the following is a requirement for a dental assistant to legally perform

A. A minimum of 5 years of chairside experience
B. Successful completion of a Board-approved course
C. A Bachelor’s degree in dental hygiene
D. Direct supervision by a dental hygienist

through a Board-approved program to perform specific expanded functions.
5. During the application of a topical fluoride gel, what is the most important step to
prevent fluoride toxicity?
A. Asking the patient their favorite flavor
B. Using a high-volume evacuator throughout the procedure
C. Ensuring the patient does not swallow the excess gel
D. Brushing the teeth immediately before application
🟢 C. Ensuring the patient does not swallow the excess gel
🔴 RATIONALE: Ingesting high concentrations of professional fluoride can lead to
acute toxicity; saliva ejectors and proper tray fit are used to minimize ingestion.
6. Which cement is most commonly used for the cementation of orthodontic bands
due to its fluoride-releasing properties?
A. Zinc Phosphate
B. Polycarboxylate
