Question

Explain the concept of Risk vs. Benefit with regards to dental radiography.

Answer 1

Risk :

There’s no denying that X-rays expose you to small levels of radiation, and the effects are cumulative when exposed to multiple sources over time. This is why the radiograph operator stands aside or even leaves the room before pressing the trigger that releases X-rays to capture an image.

• Radiation from dental X-rays represents only about 2.5 percent of the doses you receive from other medical radiographs.
• About half of your total overall radiation exposure comes from medical X-rays. The rest comes from soil, radon, and other sources of “background radiation.”
• If your dentist uses digital X-rays instead of developing images on film, your exposure is even lower.
• You wear a “bib” over your chest, abdomen, and pelvis while receiving dental X-rays to protect your vital organs from unnecessary radiation exposure. A thyroid collar is also available for people with thyroid conditions.
• Formal radiograph training is required for dental office personnel to ensure optimum safety.

NOTE: If you’re pregnant, you should avoid all types of X-rays because radiation isn’t safe for developing fetuses. Request to opt out of the X-ray procedure if you have a dentist appointment while pregnant.

Benefit :

• Many tooth and gum problems are undetectable with the naked eye, including bone infections, tumors, and decay under a filling. X-rays make it possible to catch issues early so treatment can begin promptly to ensure your dental health.
• X-rays are extremely important for detecting wisdom teeth development and determining the best method and timing for extraction.
• If you have a dental procedure performed, X-rays allow your dentist to track your healing progress and spot any problems under the surface. Quick treatment helps prevent complications.
