Specific diagnostic techniques

How do we diagnose?

There are four types of dental radiological exams:

  • Intraoral radiography: In a type of dental x-ray in which the image is taken inside the patient’s mouth. It is used primarily to identify cases of interproximal caries (between the patient’s teeth) or problems in the roots of the teeth.
  • Among the intraoral radiographs, we find those known as periapicals, which are used to obtain the complete image of the structure of roots and crowns of one or two teeth; and those called fin / bite radiographs, where the plaque is placed between the patient’s teeth to obtain an image of the crowns when the radiological plate bites. The latter is especially used in cases of interproximal caries.
  • Panoramic radiography: It is a radiological technique that shows the bony structures of the jaws, the jaw joint and the teeth in a single image. To do this, a special machine that rotates around the patient’s head is required. This type of radiography is also known as orthopantomography, since the device is called orthopantomograph. This technique is used to detect the existence or not of oral problems that would not be detected in a simple visual examination.
  • Cephalometric radiography: It is a type of technique very useful in studies prior to orthodontics. It allows to know the general state of the bones of the skull and the proportions between them, to detect morphological anomalies, placement and / or growth of the teeth and thus determine the treatment that should be followed to correct these anomalies.
  • CBCT: The acronym CBCT comes from English and refers to “Cone Beam Computed Tomography”, which in Spanish means “Computerized Tomography of Conical Beam”. It is one of the most innovative radiological diagnostic techniques on the market and allows 3D images to be obtained from the patient’s head and mouth.

The CBCT is at the dental level the closest thing to a medical CT, however the CBCT uses only the radiation dose necessary to obtain the 3D image of the bones, which means that the patient undergoes much lower radiation than with a CT scan and for less time.

What does the CBCT of the Hospital offer?

At the Dental Hospital, we have a CBCT team that allows us to make a more accurate diagnosis, in addition to assuming great comfort for our patients:

  • Lower dose of radiation.
  • Less exposure time.
  • Better appreciation of the structures.
  • More accurate diagnosis.
