Digital radiography (digital x-ray) is the latest technology used to take dental x-rays. This technique uses an electronic sensor (instead of x-ray film) that captures and stores the digital image on a computer. This image can be instantly viewed and enlarged helping the oral surgeon detect problems easier. Digital x-rays reduce radiation 80-90% compared to the already low exposure of traditional dental x-rays. Our practice uses the ultra high resolution Kodak® 6100 sensors which require minimal radiation and produce extremely high definition images.
Dental x-rays are essential, preventative, diagnostic tools that provide valuable information not visible during a regular dental exam. Oral and maxillofacial surgeons use this information to safely and accurately detect hidden dental and bony abnormalities and complete an accurate treatment plan. Without x-rays, problem areas may go undetected.
Dental x-rays may reveal:
Abscesses or cysts.
Cancerous and non-cancerous tumors.
Decay between the teeth.
Poor tooth and root positions.
Problems inside a tooth or below the gum line
Fractures in teeth or bones (Note the fracture in the image)
Detecting and treating dental problems at an early stage may save you time, money, unnecessary discomfort, and your teeth!
Are dental x-rays safe?
We are all exposed to natural radiation in our environment. Digital x-rays produce a significantly lower level of radiation compared to traditional dental x-rays. Not only are digital x-rays better for the health and safety of the patient, they are faster and more comfortable to take, which reduces your time in the dental office. Also, since the digital image is captured electronically, there is no need to develop the x-rays, thus eliminating the disposal of harmful waste and chemicals into the environment.
Even though digital x-rays produce a low level of radiation and are considered very safe, dentists still take necessary precautions to limit the patient’s exposure to radiation. These precautions include only taking those x-rays that are necessary, and using lead apron shields to protect the body.
How often should dental x-rays be taken?
The need for dental x-rays depends on each patient’s individual dental health needs. Your oral and maxillofacial surgeon will recommend necessary x-rays based upon the review of your medical and dental history, a dental exam, signs and symptoms, your age, and risk of disease. A panorex x-ray is especially valuable in the assessment of the development and position of wisdom teeth as well as to rule out pathology of the maxillofacial bones.
A full mouth series of dental x-rays is recommended for new patients. A full series is usually good for three to five years. Bite-wing x-rays (x-rays of top and bottom teeth biting together) are taken at recall (check-up) visits and are recommended once or twice a year to detect new dental problems. Bite-wing x-rays are not typically adequate for the evaluation of third molars.
