Dr. Oz has been covering dental topics lately. One recent topic involved radiation exposure with the x-ray exposure of dental images. He recommended the use of lead (or similar) aprons—I agree. One of the most exciting developments in recent years has been the advent of digital radiography. Most dentists now use digital sensors rather than film for x-ray exposures. The result is fantastic images, which are easily e-mailed and significantly less radiation exposure. X-ray exposure has always been pretty minimal in dentistry when compared to medicine. One CT or MRI scan is probably about the same amount of radiation a person will receive with a lifetime of dental decay finding x-ray images (or at least a big chunk of your life). I know this is a much bigger topic than space allows, so feel free to contact me with any questions at www.levyhoffman.com.
