DRC Regulatory Compliance & Legal Framework 3 — Questions and Answers
Question 1: Which organization publishes the guidelines most commonly used to determine radiographic selection criteria in U.S. dental practices?
- The American Dental Association (ADA) and FDA jointly (Correct answer)
- The American Dental Hygienists' Association (ADHA) alone
- The Joint Commission on Dental Accreditation (JCDA)
- The World Health Organization (WHO)
Correct answer: The American Dental Association (ADA) and FDA jointly
The ADA and FDA jointly published 'Dental Radiographic Examinations: Recommendations for Patient Selection and Limiting Radiation Exposure,' the primary U.S. guideline document.
Question 2: A patient refuses to have radiographs taken. The dental hygienist's legally appropriate response is to:
- Document the refusal, inform the dentist, and note limitations this places on care (Correct answer)
- Proceed with the examination without radiographs and say nothing
- Dismiss the patient from the practice immediately
- Require a signed waiver before any treatment can begin
Correct answer: Document the refusal, inform the dentist, and note limitations this places on care
Patients have the right to refuse treatment; the hygienist must document the refusal and inform the dentist, as this may affect the standard of care provided.
Question 3: Lead aprons used for patient protection in dental radiography must be stored:
- Hung or laid flat to prevent cracks from forming in the lead lining (Correct answer)
- Folded tightly to save storage space
- In a sealed container to prevent radiation contamination
- Submerged in disinfectant solution between uses
Correct answer: Hung or laid flat to prevent cracks from forming in the lead lining
Folding lead aprons creates cracks in the lead lining that reduce their shielding effectiveness; they must be hung or laid flat.
Question 4: Radiation monitoring badges (dosimeters) worn by dental staff should be exchanged and read at minimum:
- Monthly or quarterly, depending on state regulations (Correct answer)
- Once per year
- Only when symptoms of radiation exposure appear
- Every five years
Correct answer: Monthly or quarterly, depending on state regulations
Most state regulations require radiation monitoring badges to be exchanged and analyzed monthly or quarterly to track cumulative occupational dose.
Question 5: Which of the following describes the legal concept of 'res ipsa loquitur' as it might apply in dental radiology litigation?
- The injury (e.g., radiation burns) speaks for itself, implying negligence without specific proof (Correct answer)
- The patient must prove the exact cause of their radiation injury
- The dentist is automatically exempt from liability for equipment malfunctions
- All radiation injuries are automatically compensated by malpractice insurance
Correct answer: The injury (e.g., radiation burns) speaks for itself, implying negligence without specific proof
Res ipsa loquitur ('the thing speaks for itself') applies when an injury like a radiation burn would not normally occur without negligence, shifting the burden toward the defendant.
Question 6: The maximum permissible dose (MPD) for occupationally exposed dental workers per year is:
- 50 millisieverts (5 rem) (Correct answer)
- 1 millisievert (0.1 rem)
- 100 millisieverts (10 rem)
- 500 millisieverts (50 rem)
Correct answer: 50 millisieverts (5 rem)
The NCRP recommends an annual MPD of 50 mSv (5 rem) for occupationally exposed workers in dental and medical settings.
Question 7: When storing digital radiographic images in a patient's electronic health record (EHR), which compliance requirement applies?
- HIPAA Security Rule requirements for encryption and access controls (Correct answer)
- Only state dental board record-keeping minimums apply
- Images must be printed and stored in paper form
- No specific regulations govern digital dental images
Correct answer: HIPAA Security Rule requirements for encryption and access controls
Digital radiographs stored in EHR systems are protected health information (PHI) subject to HIPAA Security Rule requirements including encryption and audit controls.
