DRC Regulatory Compliance & Legal Framework 2 — Questions and Answers
Question 1: Which federal agency is primarily responsible for regulating radiation-producing equipment used in dental offices?
- The FDA's Center for Devices and Radiological Health (CDRH) (Correct answer)
- The Environmental Protection Agency (EPA)
- The Nuclear Regulatory Commission (NRC)
- The Occupational Safety and Health Administration (OSHA)
Correct answer: The FDA's Center for Devices and Radiological Health (CDRH)
The FDA's CDRH regulates the manufacture and performance standards of radiation-producing equipment, including dental X-ray machines.
Question 2: Under the ALARA principle, which action best demonstrates regulatory compliance during pediatric radiography?
- Using the fastest image receptor available and the smallest field size (Correct answer)
- Repeating exposures until diagnostic quality is perfect
- Using adult exposure settings to ensure adequate penetration
- Avoiding thyroid collars to reduce positioning time
Correct answer: Using the fastest image receptor available and the smallest field size
ALARA compliance in pediatric patients requires using the fastest receptor (F-speed or digital) and rectangular collimation to minimize dose.
Question 3: A patient requests copies of their dental radiographs before transferring to another provider. Under HIPAA, the dental office must:
- Provide copies or transfers within 30 days of the request (Correct answer)
- Deny the request if images are older than 2 years
- Provide originals only, not copies
- Require the new provider to request records directly
Correct answer: Provide copies or transfers within 30 days of the request
HIPAA grants patients the right to access their own health records, including radiographs, and the provider must comply within 30 days.
Question 4: State dental practice acts typically delegate authority for dental hygienists to take radiographs under what condition?
- Under the general supervision or prescription of a licensed dentist (Correct answer)
- Only when a dentist is physically present in the operatory
- Without any supervision once licensed
- Only in public health settings
Correct answer: Under the general supervision or prescription of a licensed dentist
Most state dental practice acts require that radiographs be taken under the general supervision or prescription of a licensed dentist.
Question 5: Which document must a dental facility maintain to demonstrate compliance with state radiation safety regulations?
- Equipment inspection and calibration records (Correct answer)
- Patient satisfaction surveys
- Staff continuing education transcripts only
- Manufacturer's marketing materials
Correct answer: Equipment inspection and calibration records
State regulations require dental facilities to keep equipment inspection and calibration records to prove machines operate within safe parameters.
Question 6: When a dental hygienist observes that the X-ray unit's position-indicating device (PID) is cracked, the legally correct action is to:
- Immediately take the unit out of service and report it to the dentist (Correct answer)
- Continue using it until the next scheduled inspection
- Cover the crack with tape and document it
- Reduce exposure time to compensate for potential scatter
Correct answer: Immediately take the unit out of service and report it to the dentist
A damaged PID creates radiation safety hazards and the unit must be taken out of service immediately to comply with safety regulations.
Question 7: The concept of 'justification' in radiographic prescribing means:
- The expected benefit of the radiograph must outweigh the associated radiation risk (Correct answer)
- Radiographs must be justified in cost to the insurance company
- All new patients must receive a full mouth series regardless of clinical findings
- The number of films must be justified in the patient chart
Correct answer: The expected benefit of the radiograph must outweigh the associated radiation risk
Justification is an ethical-legal principle requiring that each radiographic exposure provide net benefit exceeding its radiation risk to the patient.
