X-RAY EVALUATION OF THE EFFECTIVENESS OF TREATMENT OF CHRONIC APICAL PERIODONTITIS WITH PREPARATIONS BASED ON HIGHLY DISPERSED CALCIUM HYDROXIDE

Chronic apical periodontitis is a serious problem of modern dentistry. It occupies a special place in clinical practice and requires complex etiopathogenetic therapy.

The objective of the study was to conduct an X-ray evaluation of the effectiveness of treatment of chronic apical periodontitis with preparations based on highly dispersed calcium hydroxide in the short and long term (after 6 and 12 months) using the proposed algorithm.

Material and methods. In the clinic of the Department of Dentistry of the Medical Institute of Penza State University, a dental examination and treatment of 25 patients (n=25) of the second period of adulthood with a diagnosis of «chronic apical periodontitis» (K04.5) were carried out.

Results. The results of treatment of patients with chronic apical periodontitis were evaluated on the basis of statistical data processing methods.

Conclusions. As a result of the analysis, it was found that the dimensional characteristics of the periodontal gap and the indicators of the optical density of the periapical region, determined at the stages of diagnosis, after treatment in the short and long term (after 6 and 12 months), demonstrated a persistent dynamic decrease and reflected the stabilization of the inflammatory process in the periapical region due to the effectiveness of etiopathogenetic therapy of chronic apical periodontitis, including temporary filling with preparations based on highly dispersed calcium hydroxide. The activity of reparative processes is more pronounced in the area of the apex of the tooth root compared to the zones of the lateral surface of the tooth root, which is due to the closer contact of irri- gation solutions and preparations based on highly dispersed calcium hydroxide with the apical region during the etiopathogenetic therapy of chronic apical periodontitis.
