Many of our dental patients have questions about the x-rays they receive in our Rockville dental office. In this article, we will discuss dental x-rays in Rockville Maryland, and specifically, bitewings, which all patients should receive.
The name derives from the small tabs upon which a patient bites to hold the x-ray film or sensor in place. Bitewing radiographs are among the easiest and most accurate to take, giving distortion-free results necessary for the accurate assessment and diagnosis of dental decay between the teeth. In children and adolescents, they also show developing permanent teeth. Bitewing images usually consist of four films, two on each side, which are necessary to capture all the back teeth — premolars and molars. Often only one bitewing image per side is required in smaller children.
Bitewing x-rays carry little risk for you and your children when appropriate precautions are taken. Body parts other than the teeth being examined are carefully safeguarded: Lead collars and aprons are worn to protect and shield the neck and the rest of the body. The x-ray machine’s beam is collimated (produced in a narrow column) — designed to minimize the area of exposure, keeping it focused on the teeth. The use of today’s high-speed film and digital sensor technology has significantly reduced radiation exposure, while increasing accuracy.
When And How Often
The frequency with which bitewing x-rays should be taken is not one-size-fits-all; it is a clinical decision that should be made by you and your dentist after evaluating the risks, benefits and alternatives. It will dependent upon a number of factors including: age, which in the case of children and adolescents will reflect the stage and state of development of the teeth; and the risk of tooth decay, in itself part of a number of other clinical factors. From a periodontal standpoint, it will also include periodic monitoring and evaluation of bone levels in the assessment of periodontal health.
It is not uncommon practice to have bitewing radiographs taken as often as every six to twelve months during childhood or adolescent development, or for adults with high decay rates. The alternative is that tooth decay can go undetected and progress rapidly, requiring extensive repair or even tooth loss. And that will warrant more x-ray exposure (beyond bitewings) necessary to facilitate even more extensive assessment and diagnosis necessary for tooth replacement. Longer intervals between bitewing x-ray examinations are indicated when the risk of caries (tooth decay) and periodontal disease is low.
