Abstract

One of the most frequently seen incidents during a root canal procedure is the separation of an endodontic file. The occurrence of file separation in endodontics might impede access to the apical region of the root and hinder the effectiveness of the disinfecting procedure. The presence of the fragment hinders the proper debridement of the apical canal, hence compromising the potential success of the treatment. Nevertheless, as a result of recent improvements in techniques and tools, the successful implementation of bypass or retrieval procedures has become feasible. This paper presents a case reports where the instruments were separated at various levels in the middle and apical third of maxillary and mandibular molar teeth. Successful bypass was achieved, enabling appropriate biomechanical preparation and effective debridement followed by obturation till the entire working length. The successful bypass of a separated instrument within the root canal can be achieved through a case review, utilising a well-equipped armamentarium, possessing appropriate knowledge, and demonstrating good clinical skills and expertise. This approach can be regarded as a straightforward and efficient way for managing separated instruments.

Keywords: Instrument separation, file bypass, endodontic therapy, effective debridement
