The comparative evaluation of different methods of the irrigation of root canal systems during the endodontic treatment

The article is devoted to the advantages of ultrasonic technologies in endodontics. One of the issues of the extraction of teeth is the appearance of complications after the pulpitis and periodontitis treatment. It is often connected with the inability of the irrigant to fight the pathogenic microflora of the root dentin. The aim of the research was to find and present to the dental society the method of fighting the microflora of the roots of the teeth. In our research we compared different types of influence on the root microflora with the help of NaOCl solution, the irrigator Rinse-endo and ultrasonic preparation of the roots using the Mini Master machine. It has been found out that the irrigation with NaOCl solution (3%) during the treatment of the chronical apical periodontitis changes only quantitative, not qualitative structure of the microflora. After the ultrasonic preparation on the stage of the treatment of the chronical apical periodontitis the increase of the amount of microorganisms has not been discovered in the majority of cases (95%), which can be a cause to allow this method during chairside treatment.
