EFDA Chairside Assisting & Patient Management 5

Question 1

A patient discloses they are taking warfarin (Coumadin) before a dental procedure. The EFDA should:

Accepted Answer

Document it in the health history and alert the dentist immediately

Answer

Warfarin is an anticoagulant that increases bleeding risk; the dentist must be informed to modify the treatment plan accordingly.

Question 2

During matrix band placement for a Class II composite, the purpose of a wedge is to:

Accepted Answer

Hold the matrix band against the proximal surface to create a tight contact and prevent gingival flash

Answer

A wedge stabilizes the matrix band at the gingival margin, creates a proximal contact, and prevents excess material at the margins.

Question 3

When a patient asks the EFDA about the cost of treatment, the most appropriate response is to:

Accepted Answer

Direct the patient to the front desk or financial coordinator for fee information

Answer

Financial discussions are outside the clinical assistant's scope and should be handled by the front office financial coordinator.

Question 4

The correct angle for placing the HVE tip during a maxillary posterior procedure is:

Accepted Answer

Parallel to the occlusal surface with the bevel facing the tooth

Answer

Positioning the HVE parallel to the occlusal plane with the bevel toward the tooth ensures efficient evacuation without interfering with the handpiece.

Question 5

Postoperative instructions following a composite restoration should include telling the patient that:

Accepted Answer

Mild sensitivity to temperature is normal and should resolve within a few weeks

Answer

Mild thermal sensitivity after composite placement is common as the pulp adjusts, and typically resolves within a few weeks.
