A retake analysis shows that most repeated radiographs are due to cone cuts. Which corrective action best addresses this?
Answer: Retrain operators on aligning the PID with the receptor
Cone cuts result from the beam not covering the receptor, so alignment technique is the root cause.
What is the primary purpose of a quality assurance program in a dental radiography office?
Answer: To ensure consistently high-quality images with minimum radiation exposure
QA programs monitor equipment, materials and procedures to keep image quality high and exposure low.
Which test is used to verify the accuracy of a dental x-ray unit's timer?
Answer: Spinning top test
A spinning top (or electronic timer tester) checks timer accuracy on conventional units.
A patient is pregnant and needs a radiograph for an acute dental emergency. What is the most appropriate action?
Answer: Take the needed radiograph using ALARA principles and a lead apron with thyroid collar
Necessary radiographs may be taken with ALARA and shielding since dental dose to the fetus is negligible.
Which record must be retained as part of the patient's chart after radiographs are taken?
Answer: The radiographs, justification, and interpretation findings
Images and documentation of necessity and findings are part of the legal patient record.
Which of the following is a recommended way to reduce the number of retakes caused by patient movement?
Answer: Explain the procedure and ask the patient to stay still before exposure
Clear communication and positioning stability reduce motion blur and retakes.
Who is ultimately responsible for the safe use of radiation in a dental office?
Answer: The licensed dentist and operators who use the equipment
Dentists and operators are accountable for safe, justified use of radiation.
