Background. Despite a significant increase in the number of publications devoted to the improvement of therapeutic and diagnostic strategies in the treatment of patients with chronic apical periodontitis, the long-term results of X-ray monitoring of therapy remain far from favorable. Also, at present, there is an increase in the prevalence of this nosological form in the structure of dental morbidity, thereby causing closer attention to patients with periodontal tissue pathologies. The purpose of the study is to evaluate the effectiveness of using the intra-channel drug “Calcept with iodoform” for the treatment of infected root canals of teeth diagnosed with chronic apical periodontitis by measuring the optical density of  the periapical bone tissue. Materials and methods. 40 patients with a diagnosis of “chronic apical periodontitis” were selected. An X-ray evaluation of the effectiveness of the therapy was carried out using the delayed obturation method, which provides for the intra-channel introduction of the “Calcept with iodoform” material. Results. The analysis of the indicators of the optical density of the periapical bone tissue demonstrated a significant decrease in the foci of destruction with subsequent osteoregeneration of the studied area as a result of the treatment. Conclusions. Indicators of optical density of bone tissue are important therapeutic and diagnostic criteria. The filling material “Calcept with iodoform” may be the drug of choice in the treatment of patients with chronic apical periodontitis.
