The aim of the study was to evaluate the possible relationship between the quality of restoration of the tooth crown, root canal obturation and periapical status of endodontic teeth. A series of X-ray images from randomly selected patient cards was studied at the Dental Faculty of the Dnepropetrovsk Medical Academy. A total of 1001 endodontically treated teeth restored by permanent restoration were evaluated independently by two experts. According to a predetermined set of radiographic criteria, the technical quality of filling the root canals of the tooth was assessed as good (GE) or poor (PE). In turn, the technical quality of restoration of the tooth crown was also evaluated as good (GR), or poor (PR). Then, the roots of the teeth and the surrounding tissues were evaluated, and according to the available treatment result were classified as successful or unsuccessful. The success rate for all endodontic teeth was 66.4 % (n ‰ 1001). Teeth with root pins had a success rate of 72.7 % (n ‰ 527), the success rate of dental treatment without pins was 64.6% (n ‰ 472). The two groups with technically good endodontics had the highest success rates. In combination with technically good restorations, the success rate was 82% (GE + GR, 82 %), in the case of technically weak restorations, the success rate was 72 % (GE + PR, 72 %). Two groups with technically bad endodontics combined with good restorations or poor restorations had significantly lower success rates (PE + GR, 55 % and PE = PR, 57 %). When assessing the periapical status of endodontic teeth, it was found that the quality of endodontic treatment, evaluated radiographically, is much more important than the quality of restoration of the crown of the tooth.
