Introduction
The Florida Dental Assistant Expanded Functions Examination assesses the
knowledge and clinical judgment required to safely perform delegated expanded
functions under Florida law. Candidates are expected to demonstrate competency in
restorative procedures, dental materials, infection prevention, radiographic principles,
patient safety, documentation, ethics, and applicable regulations governing
expanded functions. This practice examination emphasizes application of knowledge
through realistic clinical scenarios, regulatory interpretation, and evidence-based
decision-making rather than simple memorization. Questions reflect contemporary
standards expected for the 2026/2027 examination cycle and are designed to
strengthen critical thinking, procedural accuracy, and professional judgment
necessary for competent clinical practice.
Question 1
,A dentist delegates placement and contouring of a composite restoration to a Florida
Expanded Functions Dental Assistant (EFDA). Before beginning, the assistant notices
slight saliva contamination of the prepared cavity after etching. What is the MOST
appropriate action?
A. Continue with bonding because contamination is minimal.
B. Dry the preparation with cotton only and proceed.
C. Notify the dentist, re-establish isolation, and repeat the bonding protocol as
indicated.
D. Place the composite immediately before additional contamination occurs.
Correct Answer: C
Explanation: Moisture contamination can significantly reduce bond strength.
Proper isolation and repeating the bonding protocol according to manufacturer
instructions help ensure restoration longevity.
Question 2
During amalgam condensation, voids appear despite using correct instruments.
Which factor is MOST likely responsible?
A. Excessive burnishing before condensation
B. Inadequate condensation pressure and incremental placement
C. Using a smaller condenser tip
D. Delayed carving only
Correct Answer: B
Explanation: Proper incremental placement and adequate condensation pressure
minimize internal voids and improve adaptation.
Question 3
,While preparing a light-cured composite restoration, the curing light intensity
measures well below the manufacturer's recommended output. What should occur
FIRST?
A. Increase curing time without further evaluation.
B. Replace the composite material.
C. Verify the curing light, clean the tip, and correct the equipment deficiency before
use.
D. Cure from only the occlusal surface.
Correct Answer: C
Explanation: Inadequate curing light intensity compromises polymerization.
Equipment should be evaluated before restorative procedures continue.
Question 4
Which situation represents the HIGHEST risk for cross-contamination?
A. Changing gloves between patients
B. Handling chart entries with contaminated gloves
C. Wearing protective eyewear
D. Using disposable barriers appropriately
Correct Answer: B
Explanation: Contaminated gloves should never contact charts, keyboards, or other
clean surfaces because they readily transmit microorganisms.
Question 5
A matrix band repeatedly separates from the tooth during placement of a Class II
composite restoration. Which adjustment is MOST appropriate?
, A. Tighten the retainer and verify proper adaptation before restoration placement.
B. Increase curing time.
C. Use additional etchant.
D. Reduce matrix height with scissors only.
Correct Answer: A
Explanation: Proper matrix adaptation is essential to establish appropriate contours
and proximal contacts.
Question 6
A patient experiences dizziness immediately after standing following treatment.
Which response is MOST appropriate?
A. Escort the patient quickly to the reception area.
B. Place the patient upright immediately.
C. Return the patient to a safe position, assess vital signs, and notify the dentist.
D. Continue dismissing the patient.
Correct Answer: C
Explanation: Postural hypotension requires patient stabilization, assessment, and
dentist notification before dismissal.
Question 7
Which characteristic BEST indicates proper sterilization monitoring?
A. Instrument packages remain sealed.
B. Biological indicator results demonstrate successful sterilization.
C. Instruments appear clean.
D. Chemical disinfectant was used before sterilization.
