A substantial portion of clinical dental practice comprises endodontic and restorative procedures. Among these, quadrant rehabilitation frequently presents as a common and complex clinical challenge. During quadrant rehabilitation, the replacement of extensive existing restorations often uncovers structural complications such as cracks and significant loss of tooth structure. In such cases, contemporary indirect restorative techniques offer […]

Fractured instruments remain a major challenge in endodontic retreatment, particularly when located beyond canal curvature. This case describes the orthograde removal of a separated instrument in the mesiobuccal canal of a mandibular molar using a loop technique, after CBCT-based diagnosis and critical decision-making. Alternative approaches, including bypass, apical surgery, and extraction, were evaluated and discarded. […]

Instrument separation is a well-recognized complication in endodontic practice, and its management can significantly influence the long-term prognosis of the tooth. While some fractured instruments are readily visible and accessible, others remain hidden, particularly when located beyond canal curvatures. Non-visible fragments pose a greater challenge, as blind retrieval attempts risk excessive dentin removal, perforation, or structural weakening of the root.

The management of a broken file refers to handling situations where an instrument, typically a file, breaks or separates during the process of cleaning and shaping the root canal. This can occur due to excessive force, inadequate instrumentation technique, or the presence of challenging anatomical features within the root canal. Broken files can present a […]

The presence of a fractured instrument in a root canal is not, in itself, a cause of failure of the endodontic treatment. However, when this instrument prevents the complete disinfection and obturation of that root canal, the success rate of the treatment drops to 89 % in cases without a periapical lesion and to 47%  […]

Retrieval along with Retreatment is one of the most challenging procedures in the endodontic therapy,  This article showcases the management of a lower first molar with swparatedinstrumemnt and a periapical lesion.  In Endodontics, we are dealing  with a lot of challenges such as anatomy, endodontic mishaps, instrument separation. One of the biggest challenges is an instrument retrieval […]

Endodontic cases involving broken instruments are among the most challenging and stressful in the field. Even the top experienced endodontists will agree that removing broken tools demands unwavering calm and exceptional self-control. This procedure isn't for everyone, as a rushed decision or improper removal can lead to failure. It's important to remember that any attempt […]

The position and anatomy of upper molars can make root canal treatment challenging, and instrument separation is common. In the presented case, tooth 1.6 had an abscess, and an attempt at root canal treatment was made. Unfortunately, the previous dentist encountered difficulties and broke a paste carrier approximately 4 mm beyond the apex. In the […]

A simple step by step technique of separated instrument removal, gaining patency and perforation repair.

This article is about showing the way of bypassing SI from both inner and outer wall, and which is correct in order to obtain satisfying outcome away from any unnecessary complications.

Fractured endodontic instruments visualized on the initial radiograph of a case that calls for retreatment may pose a great challenge to the clinician who is being asked to undertake an already complicated task. Conventional conservative management of separated instruments includes attempts to remove or bypass the fragment, or prepare and fill the root canal system […]

Fracture of root canal instruments used in root canals is a common complication in endodontics. In this article, I will demonstrate the creation of a custom loop that can be used to retrieve a broken root canal instrument
