A pregnant patient needs a radiograph for an acute dental emergency. What is the most appropriate action?
Answer: Take only the necessary views with a lead apron and thyroid collar
Necessary dental radiographs may be taken during pregnancy using ALARA and shielding because fetal dose is negligible.
Which technique modification best helps a patient with a strong gag reflex?
Answer: Expose the molar areas first and take the most sensitive areas quickly
Quick placement and exposure, with sensitive areas handled efficiently or deferred, reduces triggering the gag reflex.
What is the primary purpose of a thyroid collar?
Answer: Protect the thyroid gland from scatter and primary radiation
The thyroid is radiosensitive, and the collar shields it from scatter radiation during intraoral exposures.
Which intraoral film size is generally used for a young child with primary dentition?
Answer: Size 0
Size 0 is the smallest intraoral receptor and fits a small child's mouth comfortably.
Before exposing radiographs, what should be done with a patient's removable partial denture?
Answer: Remove it so it does not appear on the image
Removable appliances can obscure anatomy and create artifacts, so they are removed before exposure.
A patient asks if dental X-rays are safe. Which response is most appropriate?
Answer: "Doses are very low, and we only take images that benefit your care."
Honest risk-benefit communication notes the low dose and that radiographs are prescribed based on need.
Why should a lead apron be draped to cover the patient's lap?
Answer: To reduce scatter reaching the reproductive organs
The apron shields the gonads and body from scatter radiation, which is especially important for children and pregnant patients.
