Anyone who has visited the dentist either as a child or an adult is probably familiar with dental x-rays. While most medical x-rays are performed when a bone fracture is suspected, dental x-rays are much more routine, or as close to routine as this procedure can be. For many people, they often come with regular visits to the dentist. They are also most likely familiar with the lead vest that is draped over the patient to protect the person from stray radiation.
Dental x-rays have a number of important uses. Children whose teeth are still growing in generally need x-rays every six months to monitor their development, as do adults who have had fillings or other extensive restoration work. Dental x-rays can be used to detect cavities and other forms of tooth decay that would otherwise go unnoticed. X-rays can detect gum disease and point to existent or potential signs of bone loss caused by gum disease. Those who suffer from these conditions or are at risk of periodontal disease due to smoking or dry mouth generally require more frequent observations. They are also used to monitor the progress of patients who may have impacted teeth, which is common in young adults whose wisdom teeth are be coming in.
X-rays, of course, work by passing through soft material such as skin and muscle and are absorbed by denser material, such as bones and teeth. They are relatively benign compared to many other types of radiation, but they can still present a threat in large or repeated doses. It is for this reason why patients and dental staff have traditionally worn lead aprons or a lead vest for protection. These aprons cover the person from the chin to the knees. They were far more crucial years ago when dentists and technologists used high-scatter machines that were less precise than the machines used in modern dentist offices today. Machines and procedures used now require smaller doses of radiation limited to areas less than three inches in diameter. The film used has also improved over time and requires less exposure to produce a clear image. Additionally, the machines must be checked regularly for safety standard compliance every two years. Nevertheless, nearly every dentist office still makes use of lead vests and lead aprons to shield patients and employees from the radiation, and they are required by many states. They are used more for health and peace of mind.
