“…Various techniques for the removal of broken instruments have been proposed and developed. The chosen approach depends on factors such as the location of the separated instrument, the type of file, and the skill level of the clinician [2]. The techniques most used for the fragment retrieval are ultrasonics in combination with the operating dental microscope, the Masseran kit, Haedstrom files, braiding technique, apical negative pressure irrigation, glued instrument removal, the wire loop method, or a combination of them [3].…”

Endodontic instrument fracture is a prevalent challenge in root canal therapy, often leading to treatment complications and increased procedural difficulty. This case report presents an alternative way of treating an endodontic file separated in the apical third of the mesio-buccal canal of a lower molar. Due to the strategic importance of the tooth, the considerable apical curvature and patient’s requirements, the clinicians opted for deliberate extrusion of the broken fragment into the periodical tissues, thus hermetically sealing the endodontic space. This approach has the potential to offer a less traumatic treatment option under certain conditions. Keywords: separated, file, fracture, management, alternative

“…Intentional replantation (IR) refers to the deliberate extraction and subsequent reinsertion of an endodontically treated tooth into its socket with the aim of correcting an evident clinical or radiographic endodontic failure. This method is recommended in cases where an instrument is lodged in the canal and cannot be removed with nonsurgical techniques, when a posttype crown restoration necessitates retreatment, or when performing apical surgery would result in excessive bone loss leading and a risk of damage to vital structures [ 7 , 8 ]. Removing a broken instrument from the root canal system is complicated and requires specialized training and experience, as well as a deep understanding of the available methods, techniques, and equipment.…”

Instrument fracture in the root canal system is an unpleasant incident that may occur during root canal treatment. Comprehensive cleaning of the root canal system is often impossible in the presence of a broken instrument. Therefore, it is often imperative to remove the broken fragment from the root canal system. To date, various methods have been proposed for the removal of broken instruments from the root canal system. However, no consensus has been reached on a safe technique with a high success rate for broken instrument removal. This case series reports six cases of successful removal of broken instruments using different methods including the ultrasonic, tube‐and‐glue, tube‐and‐wire, tube‐and‐internal shaft, and the forceps techniques and also provides a brief review of the relevant literature.

“…However, complications can emerge during root canal treatment, one of which is instrument fracture, occurring at an incidence ranging from 0.25% to 10%. 1 , 2 , 3 , 4 , 5 The removal of a fractured instrument that is visible under the operating microscope is generally considered manageable, while addressing non-visible fractured instruments presents more challenges with current techniques, often resulting in unpredictable outcomes. 5 Here, we present a case involving successful removal of an invisible fractured instrument from a mandibular first molar.…”
