“…A recent study reported that a majority of the respondents (79.1%) reported a poor success rate in the removal of fractured instruments from the apical third in comparison with the middle third and coronal third [ 27 ]. File retrieval from the apical third increases the risk of a perforation and weakens the tooth structure due to excessive dentin removal, as well as increases the chances of ledge formation and extrusion of separated instruments beyond the apex [ 28 ]. The majority of the endodontists (64.8%) also presented a poor success rate in the removal of file instruments from the apical third and tended to bypass (66%) or leave (34%) the instruments fractured in the apical part of the root canal [ 27 ].…”

Background. Despite of having improved endodontic file designs as well as the reinforced metal alloy file structure, intracanal endodontic file separation (EFS) is still a very problematic and worrisome dental incident, which usually occurs without any visible signs of permanent deformation. Further, there have been conflicting reports regarding the clinical significance of leaving separated files within root canals. Aims. The aim of this study was to look into the current perceptions and awareness about file separation during endodontic treatment among the dental house officers (DHOs). Materials and Methods. A novel validated questionnaire comprising of 15 close-ended questions was distributed anonymously via Google Forms through email to 1100 DHOs across Pakistan. The questionnaire consisted of two parts: the first component (Section I) collected demographic data and the second component (Section II) investigated the causes of EFS during root canal treatment. Following the completion of socioeconomic information, including age and gender, the DHOs were asked to answer a few questions about the various reasons for endodontic instrument fracture. Results. A total of 800 responses were recorded, with an effective rate of 72.8%. The majority of the DHOs ( p value < 0.001) perceived that endodontic instrument fracture occurred in the posterior (61.5%) and apical third of the canal (50.5%) and in older permanent dentition (67.3%), possibly due to patient anxiety (62%). Better choice of instrument (61.15%), operators’ experience (95.3%), knowledge (87.5%), and proper root canal cleaning (91.1%) are believed to be the vital steps in reducing endodontic file separation/fracture. Furthermore, majority of them ( p value < 0.001) perceived that stainless steel was a superior alloy for filing instruments. Manual files tend to be more prone to fractures due to repeated use than rotary files. Conclusion. This study demonstrated that young DHOs had adequate knowledge and awareness regarding the potential predisposing factors and handling techniques for EFS. This study thereby provides an evaluating tool to access the insights of the current perceptions and awareness of DHOs concerning EFS.

“…[1] Separation of instruments compromises the outcome of endodontic treatment by preventing access to the apex and blocks the passage of irrigants to reach the apical level and it may reduce the prognosis of treatment. [23] Cleaning and shaping below the level of separated instrument is generally not possible with endodontic treatment, they decrease the prognosis. [4] Prognosis in this case depends on the infection in the canal, condition of periapical region, condition of canal below the separation (infected or not), and the level of separated instrument in the canal.…”

Separation of instrument in the root canal is a common mishap that occurs during the cleaning and shaping procedure. So many different methods have been developed to retrieve fractured instruments from root canal. Separated instrument leads to incomplete cleaning of root canal and eventually causes posttreatment disease. For successful completion of treatment, a separated instrument must be retrieved and if not, a bypass must be attempted. This article presents four cases requiring removal of separated instruments from the root canal. All four cases were successfully treated by conservative means of instrument retrieval by using two different techniques.

Instrument separation during root canal treatment is one of the most unpleasant mishaps. Several techniques have been described to retrieve the separated instruments; however, they generally require specific tools that are not always available at dental clinics. This case report aims at presenting a simple alternative technique for the removal of root canal instruments separated during endodontic treatment. Endodontic retreatment was indicated for a maxillary lateral incisor of a 19-year-old patient. The radiographic examinations revealed the presence of a separated (fractured) instrument beyond the apical part of the canal. Retreatment was initiated by removing the obturated materials. After several unsuccessful attempts to retrieve the broken fragment, a hypodermic needle with chemically self-cure acrylic resin was used under an endodontic microscope to remove the separated fragment successfully. The retrieval technique used in this case was safe, simple, and low cost.
