Abstract

Introduction: preservation of the structural integrity of the permanent natural dentition is crucial for maintaining dental functionality and aesthetics.  Consequently, surgical endodontics treatment represents a last resort for achieving this objective, and its failure may jeopardize tooth survival. Endodontic failures can be addressed by non-surgical or surgical endodontic retreatment. Among the most common causes of endodontic failures are root perforations, also known as artificial openings caused in the root walls caused by iatrogenic factors, resorptive processes, among others. The objective to evaluate the efficacy of platelet-rich fibrin (A-PRF) in periapical surgery to promote bone regeneration and improve the prognosis of teeth with root perforations, Additionally, determine the impact on bone regeneration after periapical surgery. Methodology is experimental transversal because a case study is applied, taking information from the patient before, during and after the process. Results: reference data is obtained in the literature that reports an incidence of perforations between 0.7% and 10%, and the percentage of teeth extracted due to endodontic failure with perforations is between 2.9% and 4.2. % depending on the time elapsed since the perforation, the size of the perforation and in which root third the perforation is located, with the middle or cervical third having a poor prognosis. Considering the analysis of these data, the result is that the application of the protocol described in this report can be used as an alternative reference to the failure of non-surgical endodontic treatment to preserve a functional dental structure in the mouth for a greater amount of time. General Area of Study: Odontology. Specific area of study: Endodontic. Type of study: Clinical case.
