X-ray examinations were used to analyze compliance with the basic requirements of clinical guidelines for modeling pin inlays on the root surface. For this purpose, the X-ray assessment of CBCT studies of maxillary and mandibular teeth and the conclusions of the forensic medical examination were analyzed. The results of the forensic medical examination in cases related to the poor-quality manufacture of this type of prosthesis in the period from 2013 to 2022 were analyzed. The results showed that in 10% of lawsuits related to non-removable prostheses, there were claims about the quality of the prosthesis. This share has not decreased over the past 10 years, and the lawsuits concerned the quality of manufacture of root canal tabs. At the same time, errors and complications when using tabs in root canals were identified in 50% of cases, and in 50% of cases they were associated not with poor-quality materials or imperfect treatment techniques, but with incorrect dental technique. An X-ray assessment of the quality of the formation of root canal inlays by dentists showed very low compliance with clinical recommendations. Compliance with clinical guidelines is very low. The correct residual wall thickness of the root canal was determined only in the following cases, the correct residual wall thickness of the root canal was determined only in 37% of cases. The recommended ratio of the tab pin length (2/3 of the root length) was determined only in 2% of cases. Compliance with the ratio of crown and root length for restored teeth was required only in 2% of all studied cases. The ratio of crown height to inlay pin length was 1:2 or 1:3 in only 2% of cases.
