Nowadays, in our practice, we have more and more patients asking about the risks of Xrays’ radiations. So, are X-rays really needed? How often should I have X-rays taken? How can it affect my safety?
First of all, it is important to understand that an exposure to any radiation can be dangerous. X-rays are electromagnetic radiations. They can affect our health if they are used in an abusive practice.
We are surrounded by radiations: sun’s radiations, TV’s radiations, cosmic’s radiations, radio waves, terrestrial’s radiations, tobacco…
Radiations are measured in Sievert (S) and most of the time we talk about micro Sievert.
Therefore, improvements of X-ray devices makes them less dangerous. X-ray equipment, are then sending very light levels of radiations. Make sure that your dentist uses a collimated X-ray machine with digital X-ray, which means less radiations and less risks of radiation scattering.
We consider that the best amount of radiography for our patient is around 1 panoramic X-ray every 3 years and 2 bitewings X-rays every year or 2 years.
