RETROSPECTIVE ANALYSIS AND CLINICAL OBSERVATIONS OF REGENERATIVE FEATURES OF PERIAPICAL TISSUE

Abstract

Abstract Background. Chronic forms of periodontitis are accompanied by changes in periapical tissues, untimely diagnosis and lack of full mechanical treatment increases the number of patients diagnosed with chronic periodonitis. Periodontitis, which leads to destructive changes due to a long-term inflammatory process in periapical tissues, is especially dangerous. For this reason, the problem of treating destructive forms of periodontitis is relevant in modern dentistry. The purpose of the study is to study the regeneration of periapical tissues after treatment of patients with chronic forms of periodontitis. Methods. A retrospective analysis of the destruction and restoration of periapical tissues before and after treatment in the period of 3-6 months was carried out in 20 patients. Results. According to the results of a retrospective analysis of X-ray studies, bone tissue destruction of varying degrees was revealed in 20 patients. Poor preparation of the root canals was due to a number of factors, the main one being the anatomy and topography of the root canals. Of the 20 patients requiring treatment for chronic periodontitis with varying degrees of destruction, 16 patients came to the next stage and underwent endodontic treatment. After the treatment, conical preparation of the root canals and the quality of obturation to the radiographic apex of the root were radiographically revealed. In patients with clinical signs of periodontitis, an X-ray examination was performed after 3 months, in patients without clinical manifestations - after 6 months. After 3 months, the X-ray showed a decrease in the foci of bone tissue destruction in the area of the causative tooth, and positive dynamics were determined. Conclusion The study of periapical tissue regeneration after treatment of patients with chronic forms of periodontitis showed that effective apical preparation, high-quality irrigation and root canal filling increases the degree of regeneration in the periodontium. Healing in the periapical tissues is crucial for the success of root canal treatment.
