You will also be asked to wear a leaded apron to protect the rest of your body during the procedure. About one in eight scans ordered for kids is a CT scan. Dental x-rays are not usually taken at this first visit, but there are. Many dentists and parents believe this is a little too early but agree that two years of age is appropriate. You will be asked to stand or sit in the center of the unit, where the technician will carefully position and secure your head, and then place a bite-blocker in your mouth to ensure your teeth are correctly aligned. The American Academy of Pediatric Dentistry recommends that a child have their first dental visit at the age of one year.
Bite wings (intra oral) and/or panoramic X-rays may be recommended. For high caries risk patients, the American Academy of Pediatric Dentistry (link) recommends X-rays every 6 months to 1 year.
For children and teens, X-rays are used to find decay and damage to fillings, and to monitor tooth growth and development. This X-ray requires that a patient be able to sit or stand still for 12 to 18 seconds. This shadow may obscure a clear view of the anterior region of the jaws. However, a ghost shadow of the cervical spine is formed when the anterior teeth are imaged because the X-ray beam originates from behind the patient’s head. In preparation for the procedure, the dental technician will ask you to remove any metal objects such as jewelry. This is helpful for children who gag easily or who have small mouths. The cervical spine may be seen in focus on a panoramic radiograph on the most posterior parts of the image. The X-ray lasts between 12-20 seconds, so it’s quite easy to perform. Instead of relying on film placed inside your mouth, the X-ray technician will direct the X-ray machine to project a beam through your mouth onto a film that’s rotating opposite the X-ray tube. And, you may not need to have dental x-rays every year, or even every two. The dose you receive is about 10 of the old systems. So how does it work? According to by the Radiological Society of North America, the X-ray tube rotates in a semicircle around your head, starting at one side of your jaw and ending on the other. The good news is that the digital dental x-ray technology we use in our practice has sensors that are so responsive to low radiation that you are exposed to far less radiation than with the old film-based radiography. Unlike traditional X-rays like bitewing X-rays, panoramic dental X-rays are extraoral, meaning the imaging machine is outside of your mouth.
