X-ray diagnostics comprises examination of internal structures of the human body by various methods using X-rays.
In dental practice of our Medical Center for diagnostics and quality control of treatment we use the following methods:
Intraoral radiography– the image of a small portion of the jaw on a film or a radiovisiograph (RVG) sensor, sometimes called a sighting snapshot. Advantages of this method are accessibility and the least radiation burden among other types of research. Among the shortcomings: some discomfort for the patient when installing a sensor or film in the oral cavity and a significant deterioration in diagnostic information with small errors in the procedure.
Panoramic tomography (orthopantomography) – obtaining images of the elements of the dentoalveolar apparatus with the help of a special device - orthopantomograph. This method provides general information on the condition of the teeth and bone tissue of the jaws with a relatively minimal radiation load, but in most cases, projection overlaps and projection distortions of the anatomical structures reduce the reliability of the information obtained and make image analysis difficult.
Teleradiography (TRG) - obtaining a skull image in a straight or lateral view, which gives the doctor an opportunity to evaluate the structure of the dentoalveolar apparatus, to identify possible disorders and to predict the effect of treatment at its stages. These analytical data (cephalometry) are necessary for qualitative orthodontic intervention.
Cone-beam computer tomography (CBCT) – is an examination that provides three-dimensional data, which is an advantage compared to radiography, since there are no projection overlaps and projection distortions typical for two-dimensional studies. The radial load with CRCT is greater than with other examinations for the needs of the dentist, but it provides incomparably more reliable information. In addition, modern equipment allows you to minimize the radiation load by reducing the scanning area and changing exposure parameters in accordance with the purpose of the study.
