Despite the continuous development of technology in modern dentistry, perforations of the hard tissues of the tooth remain one of the most serious complications of primary and one of the main types of repeated endodontic treatment. However, reliable data on the prevalence of this iatrogenic complication remain unknown. This is due to the commercialization of dental services and the importance of the status, professionalism and authority of the modern doctor in the eyes of the patient, which, in turn, negatively affects the quality of treatment. The aim of our research was to study the prevalence and causes of complications in endodontic treatment, including perforations, identification and practical application of the most effective treatment in the clinical case of combined perforation with evaluation of the outcome in dynamics. Almost 95% of endodontic practitioners have experienced perforations, so solving the problem of effective treatment of this complication remains an important issue in modern endodontics. According to our questionnaire of dentists, perforation, as a result of endodontic treatment, was 10.5% of all complications. The lateral perforation of the root canal was observed in 53.8%, furcation perforation – in 29.3%, perforation of the bottom of the tooth cavity – in 14.1%, perforation at the top of the root canal – in 2.0%, combined – in 0, 8%. We identified the main causes of perforations, namely: lack of magnification, incorrect selection of tools and methods of working with it, insufficient knowledge of the anatomy of the tooth cavity and root canals and lack of time for patient treatment. The survey showed that many physicians are not sufficiently informed about the latest advanced materials and techniques of perforation obstruction, which may reduce the success of treatment of this complication. MTA ProRoot (Dentsplay) became the material of choice for closing the perforation of 87.8% of the surveyed contingent of doctors. In the treatment of combined perforation with this material, we obtained a positive dynamic of both clinical and radiological indicators in the short and long term.
