The influence of modern endodontic technologies on processing of root canals in the treatment of apical periodontitis
Abstract
The aim of this study was to conduct clinical and laboratory studies in the process of complex treatment of patients with chronic apical periodontitis and assessing the effectiveness of endodontic technologies of root channels with the use of self-adapting the SAF files, ultrasonic treatment, 3% solution of sodium hypochlorite and 2% chlorhexidine solution. In the process, were selected 77 patients with a diagnosis of chronic apical periodontitis. Then there were formed 3 groups and 6 subgroups. In the control subgroups, we conducted instrumental and medicamental processing of root canals with manual instruments using a 3% solution of sodium hypochlorite and 2% chlorhexidine solution. In the comparison group were given the combined treatment with ultrasonic activation of irrigants (3% sodium hypochlorite, 2% chlorhexidine solution.) and the SAF system with the same irrigation solutions, respectively. Clinical impact evaluation method dresses: women's treatment on the outcome of endodontic treatment was performed according to the frequency of the diagnosed complications a year after treatment of apical periodontitis. The structure of the biofilm root canals was studied using scanning electron microscopy (SEM) using a microscope Quantum 3D (USA).According to the results of clinical and microbiological studies have observed a positive trend to reduce the number of the designated pathogens when irrigation SAF, as in the application solution of 3% sodium hypochlorite and 2% chlorhexidine solution.
