DANB CDA Details

DANB CDA is voluntary and not referenced in state regulations; employers may prefer it

Radiology Certification Details

No separate radiology certification required by the state; supervising dentist delegates radiography duties and ensures competency

The DANB Certified Dental Assistant (CDA) credential is the nationally recognized standard, though not all states require it. Radiology certification is commonly required to take dental X-rays. CPR certification is required in most states.

Expanded functions allow dental assistants to perform additional procedures beyond basic chairside duties. Some states require a separate Expanded Functions Dental Assistant (EFDA) credential, additional training, or specific coursework to perform these duties.

Direct Supervision Procedures

All expanded duties as delegated by the supervising dentist

Dental assistants work under varying levels of supervision depending on the procedure. Direct supervision means the dentist must be physically present and authorize the procedure. Indirect supervision means the dentist is on-site. General supervision means the dentist has authorized the procedures but need not be on the premises.

Regulatory Board

Dental assistant credentials must be renewed on schedule. Most states require continuing education covering infection control, radiology safety, and dental practice updates. CPR certification renewal is required in most jurisdictions.

Reciprocity Requirements

• •No credential to transfer; state is unregulated
