THE ROLE OF ENDODONTICS IN THE TREATMENT OF CHRONIC ODONTOGENIC DISEASES IN PREPARATION FOR PROSTHETICS

Background. When planning orthopedic restoration of significantly destroyed teeth with signs of apical periodontitis, it is necessary to assess the complexity of root canal anatomy as one of the factors influencing successful endodontic dental treatment. Modern approaches in endodontics allow in most cases to achieve the restoration of bone tissue, as well as the elimination of the focus of chronic infection, which allows for subsequent orthopedic dental treatment in order to restore their function and increase the percentage of survival in the oral cavity. Purpose. Improving the efficiency of orthopedic restoration of teeth with chronic odontogenic infection. Materials and methods. 64 patients aged 18 to 45 were examined. All had clinical signs of failed endodontic treatment of the incisors in the upper and lower jaws with a dark, radiolucent focus in the apex region, as well as significant destruction of the crown requiring orthopedic restoration. The assessment of radiographic parameters was based on CBCT, and mobility was assessed clinically. The results were evaluated after 6, 12, and 24 months. Results. All patients showed different signs of restoration of the bone tissue after 6 and 12 months and complete restoration of the bone tissue 24 months after the treatment. No pathological tooth mobility was found 24 months after the end of treatment in 100% (primary endodontic treatment) and 97.5% (repeated endodontic treatment) of patients. Conclusion. The analysis of the anatomy of the root canals, and, accordingly, the complexity in biomechanical cleaning and washing of the root canals affects the decision to carry out treatment in one or two visits.
