Abstract
Despite the high level of instrumental provision in therapeutic dental procedures, which allows the use of modern technologies, a wide selection of filling materials, complications during endodontic dental treatment are not uncommon [1–3].

Noteworthy is not only the number of complications, but also a fairly frequent increase in the frequency of severe consequences of treatment, which lead to irreversible changes in the tissues of the maxillofacial area and disturbances in their function [4].

 Keywords: filled dental canals, periodontal condition of the treated tooth, evaluation of endodontic treatment.
