Knowledge of the nature and duration of the violations of adaptive-compensatory reactions of the periodontium depending on the physico-chemical properties of endosealers is an important part of endodontic treatment. The aim is to reveal the conditions of the experiment peculiarities of morphological changes of periodontal tissue in direct contact with the main filling material for root canal. Material and methods. The traditional method of obturation by modern endosealers was used to seal the root canal of teeth of experimental animal. Results of the study demonstrated the bio-compatibility of new experimental material Real Seal. Conclusion. The data obtained justify a differentiated approach to the choice of the root filling material for teeth with a healthy periodontosis.

The article presents the study of formation mechanisms and periodontitis course in patients with subclinical stage of HIV-infection. The examination of 45 patients has enabled the division of patients into three basic groups: patients with periodontitis and HIV-infection; patients with periodontitis; and HIV patients without periodontitis. It has been determined that the patients with periodontitis and subclinical HIV-infection have developed local inflammatory reaction with infection, activation of anti-inflammatory cytokines in parodontal recess fluid. It has been proved that the causative factor of frequent and durable relapses in parodontal pathology with clinical HIV-infection was the development of pathologic process with endotoxicosis syndrome and imbalance of lipid peroxidation and antioxidant system
