Nowadays, as dentists, we take full advantage of the possibilities of modern technology in order to make a better and more specific diagnosis. This leads to a more accurate treatment and a predictable final result.

Why do we have to take dental X-ray images?

  • at each initial dental appointment – to gather enough information about the patient’s dentition. We need a few small images or a panoramic image. They are required so that we can make a detailed examination and present accurate information about your condition.
  • if there is a possibility of hidden processes – most often interdental caries are not visible during dental examination and it is recommended to take small images for caries diagnosis. This allows a timely reaction before the caries reaches deeper stages.
  • root canal treatment  follow-ups – old root canal treatments should be checked regularly, especially if there is a doubt about poor treatment. In such cases, developing asymptomatic chronic processes can get worse at any time (for example, during our summer vacation). Each new root canal treatment must be performed with a minimum of three photos – before, during and after.
  • dental implants placement – nowadays implant placement is predictable and precise. This is possible with the help of modern CBCT technology, also known as 3D. Provides the most accurate information about the volume, height and density of the bone and the ability to plan the most appropriate implant size for the selected spot.  It is mandatory for us to perform CBCT examination before implant placement, as well as to control it with small X-ray images during the placement and immediately after. Implants are monitored regularly over the years with small x-rays to check for inflammatory processes or bone atrophy (physiological or pathological), because these conditions around the implants are treatable if diagnosed in time.
  • other situations – before orthodontic treatment, for detection and treatment of deformities, lack of tooth germs, examination of retained teeth, examination of size and quality of bone, and many other answers that are obtained by dental X-rays. Individually, according to the need, it is determined which will be the most suitable photo.

Types of X-ray images?

  • small segmental X-rays – most often used to establish the presence of caries, follow-up of root canals, periodontal and bone condition, follow-up of implants.
  • panoramic X-ray – they give a complete picture of the dentition, including information about the condition of the temporomandibular joint.
  • CBCT (3D) – the most detailed images with accurate and good details, helping in absolutely all cases. This is the most modern method of imaging, in which we receive accurate information and can make the correct diagnosis, which will lead to appropriate treatment.
  • cephalography, X-rays of TMJ – used in orthodontic treatments and total rehabilitation of the dental and maxillofacial apparatus.

Are X-rays harmful?

X-rays are a type of electromagnetic radiation such as light, radio waves, ultraviolet and infrared rays. A person absorbs different doses of radiation in his daily life.

It has been proven that more radiation is absorbed in the following cases:

  • inhalation of radon from the air
  • through food and water
  • gamma radiation from the ground and buildings
  • cosmic radiation

In all of the above cases, it is likely that you will absorb more radiation than from a detailed X-ray. Modern digital X-Rays have an extremely low load and irradiation time. For example, for classic dental  X-rays, 1 small dental photo is equal to 1-2 days of natural background radiation or a 2-hour mobile phone conversation. Modern digital X-rays are much more harmless and 1 small dental photo is equal to 5 hours of radiation background or a 10-minute call on a mobile phone. Panoramic photography and CBCT have a longer exposure time, but with good X-ray machines, the radiation load is quite small.

Examples of comparison:

  • radiography of the lungs = 20 small photos
  • venous urography = 600 small photos
  • computed tomography of the head = 700 small photos
  • computer tomography of the chest = 2000 small photos

Conclusion: the risk of dental photos is reduced to an absolute minimum. Your dentist will recommend the latest dental X-ray machines. Request to wear a safety collar and bib when taking pictures.

Problems and inflammatory processes that can be diagnosed early by x-rays are often hidden under visibly healthy teeth. Follow your dentist’s instructions and be responsible for your individually designed dental care and prevention plan.
