Let’s Talk Xrays With Dr. Kaitlin Haag
I thought it would be a good time to talk about X-rays! Someof the most frequent questions I get asked in the office are about X-rays. Do I/my kids really need them? Is it safe? So I thought I’d share some of the basics when it comes to dental radiography and some of my favorite resources.This is a hot topic! Literally! When people are talking about radiation and dosages, they are referring to micro-Sieverts or Sv. Four bitewing X-rays are 5 Sv. To put this in perspective, I’ll share a few other interesting facts. The average person receives a dose of 10 Sv on the average day from background radiation like sunlight. 400 Sv is the yearly dose an average person gets from eating food! Bananas are radioactive at 0.1 Sv. The EPA put a yearly limit on radiation dosage to members of the public at 1,000 Sv. The risk of harm is dependent on both the dose and the dose rate, or in other words, the time that the body is exposed to that dose. So a large dosage over a greater period of time is less concerning than that same dosage in a very short period of time. Digital radiography significantly reduces the amount of radiation that patients are exposed to. We always use a thyroid shield, and we lower the dosage to a “child-size” exposure time. In this way, I limit X-ray exposure to only that which is needed. I follow the guidelines from the American Academy of Pediatric Dentistry when prescribing
dental radiographs for infants, children, adolescents and persons with special health care needs. These guidelines were adopted from the ADA and the FDA. The table in the above link is very useful!
