Dental radiography is a common diagnostic procedure that is considered extremely safe. If you are worried that you may need a dental x-ray or are wondering if you should give up this procedure because of other medical conditions, it is helpful to consult with your dentist about what a dental x-ray involves and how they are done.

If you are a new patient, your dentist may recommend that you perform a complete series of radiological images, orthopantomography, or 3D radiography (CBCT) to assess your current oral health. Subsequently, these images can be used as a basis for comparison in future investigations. As you continue regular check-ups at six months, fewer x-rays will be needed to monitor your oral health.

But what is the radiation dose received by the patient during a radiological examination?

This depends on the radiology device used for the examination. We have dental and radiological devices with the latest technology.

  • A flight between Bucharest and London exposes a passenger at 25 µSv, X-rays equivalent to 2.5 panoramic radiographs
  • People who smoke 1.5 packs of cigarettes a day receive a radiation dose equal to 10 daily panoramic x-rays, ie 3650 x-rays done per year!
  • The daily dose of natural radiation (background radiation) to which we are exposed to is 10 µSv, equivalent to an orthopantomography, a retroalveolar radiography is only 1 µSv, and in a dental tomography (CBCT) the exposure is 4 - 50 µSv

Here are 4 reasons why dental x-rays should not be a cause for concern: 

  • We want to provide patients with the best possible dental care, but a visual examination does not tell us everything we need to know. Thanks to x-rays we can accurately diagnose and treat dental problems before they get worse.
  • 3D dental tomography provides an efficient and reliable way to measure maxillary bone density, bone crest thickness and height, and implant insertion planning. Subsequently, it allows the evaluation of osseointegration, which is, in fact, measures the success of the implant.
  • It helps us plan optimally and personalize treatments by computer simulation of the treatment or intervention.  
  • Our digital cameras emit up to 90% less X-rays than conventional cameras during an exposure.

Always tell your dentist if you are pregnant or breastfeeding, although X-rays should not be avoided as you will wear a leaded apron and thyroid collar during exposure. An artificially exposed pregnant woman can receive a radiation dose of up to 1000 µSv, without this posing any risk to the pregnancy. This dose of X-rays is equivalent to 100 x-rays.

Many parents are concerned about the impact of dental x-rays on their children. Children are more sensitive to radiation. However, the amount of radiation from a dental x-ray is considered safe for a child. Because children's jaw bones and teeth are constantly changing, it's important to keep an eye on their development. These X-ray investigations are extremely important for young patients. It helps the doctor notice how deep the cavities are and if the pulp chamber and the nerve are affected. Based on radiography, dental and maxillofacial abnormalities can be diagnosed to plan an appropriate orthodontic treatment for teeth straightening.
