Background. The success of endodontic treatment is provided by a thorough instrumental and antiseptic treatment of infected root canals, and it depends on the composition of filling material, the degree of adhesion to dentin, hermetic obturation of apical foramen, solubility of sealer. Objective. The study was aimed to evaluate the effectiveness of root canal obturation with BioRootTM RCS sealer in the treatment of patients with chronic apical periodontitis. Methods. Endodontic treatment of 23 teeth in 20 patients with chronic apical periodontitis by method of lateral compaction of gutta-percha was carried out. In the main group root canals were obturated with BioRootTM rcs, in the control group the canals were filled with Apexit Plus. the percentage of efficient or non-efficient cases was evaluated on the basis of radiographic comparison of treated chronic apical periodontitis immediately after obturation, in three, six months and one year. radiographic conditions were defined as existing state, improvement and worsening. Results. in a year of dynamic evaluation the nal results were: in the main group – 54.55% of the patients had complete bone healing, in 27.27% of cases the focus of bone destruction was decreased by 1/2 or more of the initial sizes, 18.18% – resorption lesion was decreased by less than1/2; in the control group – 33.33% of improvement, 25.0% of existing state and 41.66% of worsening. Conclusions. BioRootTM RCS using for root canals obturation in the treatment of chronic apical periodontitis we proved the high effectiveness of the treatment undertaken: complete healing or improvement of radiographic conditions of periapical bone destruction with X-ray signs of bone regeneration.
