Trends in endodontic claims in Italy.

According to the scant data available in the literature, endodontic claims are common among dental professional liability cases and the second most common type of claim. This study aimed to describe the characteristics of endodontic claims in Italy and the most frequently disputed errors, and the discussion below includes consideration of ethical and medico-legal aspects thereof. We retrospectively analysed 120 technical reports written on cases of professional malpractice in endodontics in the last 5 years. The complainant patients were males in 22.5% of the cases, while females made up the remaining 77.5%. In the dentist sample, male operators were more often involved in litigation cases (80%) than female operators. The most frequently claimed technical errors were: lack of a complete filling of root canal/s (71.7%), the perforation of tooth structure (12.7%), extrusion of sealing materials beyond the apex of the tooth (9.6%) and the fracture of an endodontic instrument (5.9%). In 1.7% of cases it was found that the expert did not make any errors performing the endodontic therapy. In only very few cases (2.7%) no therapy was considered necessary, while the most common therapeutic solution involved in endodontic misconduct was tooth extraction (53.0%). In many cases the dentist preferred to extract the endodontically undertreated tooth and substitute it prosthetically rather than trying to re-treat it. The discrepancy between the total number of cases examined and those that eventually go to court leads us to believe that the majority of endodontic malpractice cases are resolved in out-of-court settlements.
