Treatment of patients with chronic periodontitis is one of the most complex and important tasks of modern dentistry. On an outpatient basis, 134 patients were examined with endodontic treatment with two of the most common types of pastes: resorcin-formalin and zinc oxide eugenol. According to the type of paste, all the examined patients were divided into two groups: 78 patients (51.5%) whose teeth were sealed with resorcin-formalin paste and 56 patients (48.5%) with zinc oxide eugenol paste.

In the structure of therapeutic treatment, 35% are visits for pulpitis and periodontitis. The inflammatory process in periodontal disease is the main cause of tooth extraction. On an outpatient basis, 134 patients were examined with endodontic treatment with two of the most common types of pastes: resorcin-formalin and zinc oxide eugenol. According to the type of paste, all the examined patients were divided into two groups: 78 patients (51.5%) whose teeth were sealed with resorcin-formalin paste and 56 patients (48.5%) with zinc oxide eugenol paste. According to the study, in the group of teeth previously treated with resorcin-formalin paste, more than 2/3 were molars (77.0 + 2.2%), every fifth tooth was premolar (19.1 + 2.0% ) and the least were the front teeth (3.9 + 1.0%).
