[Morphology of root dentine in teeth extracted because of chronic apical periodontitis in various irrigation protocols].

The purpose of the study was to evaluate the degree of purification of the deltoid root canal branching during endodontic treatment of teeth. Morphological assessment of dentine of 14 extracted incisors and premolars in patients aged from 24 up to 56 years with the diagnosis chronic apical periodontitis was conducted in two experimental groups: main (1 group, 7 teeth) and control (2 group, 7 teeth). In the 2 group conventional root canal treatment was carried out with processing of 3% solution of sodium hypochlorite and final sealing with gutta-percha pins by lateral condensation. In the 1 group root canals were additionally irrigated by 3% sodium hypochlorite solution by means of the RinsEndo device. Based on the study results we recommend using the hydrodynamic method of irrigation of root canals with 3% sodium hypochlorite solution in endodontic treatment of patients with chronic apical periodontitis.
