The summary aim of this study was to compare the quality of root canal obturation teeth depending on the chosen method of machining and filling. To achieve the objectives conducted a laboratory study in which selected 70 extracted teeth with one root canal. The teeth are divided into 7 groups according to used for machining tools, methods of sealing root canal sealer and method of application. Proved highly effective sealing of the root canal using a heated gutta-percha on the media. Mechanical treatment of root canal rotating nickeltitanium instruments, the introduction of sealer using Endodontic files and reamers and application of gutta-percha cone improve the quality of its obturation.
