X-rays are able to penetrate the body and are absorbed in varying degrees, depending on the density of the tissue. Thus, the dense structures are shown with white, the soft tissues with shades of gray, and the cavities with black, the radiographs having the aspect of the negatives of photographs.

The dental radiography helps doctors to discover the problems not visible in a regular consultation such as cavities between the teeth and below the fillings, cracks or other abnormalities in fillings, decreases in bone mass associated with periodontal disease, problems in the pulp chamber or the root canal, preparation and fixation of implants, braces, and dentures.

The x-rays reveals other defects such as cysts, cancer, or other changes associated with metabolic and systemic diseases. With regards to the children, the dental radiographs are useful to see if the mouth has enough space for the entire dentition, to observe the evolution of the teeth, and the potential impacted teeth.

Also, the dental radiographs are an effective means of monitoring the health of the mouth for the adults presenting a particular risk.

They are people with extensive prosthetic devices (including fillings), those who frequently take sweetened beverages, periodontal disease patients, people suffering from xerostomia or dry mouth, and the smokers.

CRISDENT CLINIC offers the latest equipment for complete dental radiological investigations such as retro-alveolar radiography, bite-wing type x-ray, 2D or 3D CBCT Orthopantomography (Cone Beam CT).


Due to the complexity and variability of the anatomy of the dental-maxilla-facial complex, the transition to three-dimensional imaging was natural, thus developing a new imaging technique called volumetric CT scan. This technique is known under the name of Cone Beam CT or Digital Volume Tomography (DVT).

The Cone Beam Computed tomography is the newest and least radiant imaging method highlighting volumetrically and sectional the dental maxilla-facial complex.

CBCT's main advantage is the high resolution of the structures with a high degree of mineralization such as the bone and tooth, and in some circumstances can be used to highlight the changes in the sinus.

  • the cone beam computed tomography ("Cone-beam computed tomography (CBCT)") is a faster and more reliable version of the classic CT;
  • because of the use of X-ray beams of a conical shape, the size of the device, the amount of X-rays and the duration of the investigation are dramatically reduced;
  • CBCT provides 3D images that allow the implant specialist to analyze structures in the mouth in multiple positions;
  • CBCT can analyze the width of certain structures compared to the height;
  • on CBCT can also be observed other details such as cysts or included tooth; also the position of certain blood vessels or nerves that could make the implantation surgery more difficult;
  • CBCT examination shows no distortions. Demonstrates the shape and size to 1: 1 scale of your jaw's structures and provides accurate measurements of the height, width, thickness, very useful for the correct positioning of the implants;
  • the CBCT scanner rotates once around the patient's head to capture images in multiple plan, the radiation dose is being lower than for scans using the classic CT, since one short scan is enough to cover the entire area of investigation.

The images are obtained by a single rotation of 360ᵒ, being afterwards reconstructed using an imaging software, in order to obtain the 3D virtual model.

The size of the recording field (Field of View - FOV) can be chosen depending on the size of the region to be explored, ranging between 5x5 and 12x9 in the case of the PAX I3D tomography computer that our clinic has.

The important breakthrough of 3D technology, implemented in the CBCT device, is represented by the low radiation dose and the reduced time for image acquisition, while providing greater accuracy and a more accurate image.
