Case Presentation: Case I: A 32-year-old healthy female Saudi patient presented at General Dentistry Clinics at College of Dentistry, Njran University, with irreversible pulpitis of the lower left second molar. It was decided to perform root canal treatment and then to do a reconstruction reinforced by crown. During the cleaning and shaping procedures for coronal shaping, a ProTaper nickeltitanium files separated in the mesiolingual canal of the tooth tightly filled nearly 80% of the total length of the canal. The fractured instrument was retrieved.

During the cleaning and shaping procedures for distobuccal with K3™ nickel-titanium files separated in mid-root with 4 mm of file. The fractured instrument was bypass. Conclusion: Choosing the right method is a key step in the complication described above. The management technique should entail the least risk of iatrogenic complications because they can greatly affect the long-term maintenance of the tooth.|
