The most commonly used radiological technique in dentistry is intraoral periapical radiography, which is used alone or in combination with other x-ray techniques.
Intraoral periapical radiography is a complex technique for obtaining and interpreting images. The features of this technique manifest by distortions of the image of the shape and size of anatomical parts and pathological zones, vertical relationships of anatomical parts between themselves and with the zones of bone destruction. It is not always accurate to determine the number of root canals of the teeth and the degree of their obturation, measurements and densitometric calculations are not reliable. These factors contribute to diagnostic errors.
Essential in the x-ray process is the correct interpretation of the image, which can be based on knowledge about the laws of the x-ray pattern in the normal and pathological processes in the dentoalveolar region.
The results of the analysis of the radiological features of intraoral periapical radiography are presented. X-ray images of more than 750 patients aged 18 to 70 years with periodontitis, periosteal inflammatory bone cavities of small sizes were analyzed.
The features of their implementation, interpretation, use in diagnosis and treatment are discussed in detail.
The characteristic errors made during periapical radi-ography and interpretation of its results are presented and discussed.
Keywords: intraoral periapical x-ray, dentoalveolar region, regularities of the image, projection distortion, interpretation of the image.
