Removal of Two Canal Instruments from the Mesiobuccal Canal of a Mandibular Molar Tooth: A Case Report

One of the important factors that affect the success of root canal treatment is the complete removal of the pulp all the way to the root apex and disinfection of the canal. One factor that may impede this process is the existence of fractured canal instruments within the canal. In some cases, this problem can be eliminated by bypassing the broken instrument. However, this may not always be possible and the removal of the instrument is necessary. In this case report, we present the extraction of two fractured instruments inside the mesiobuccal canal of the lower left first molar of a 30-year-old female patient, performed under a microscope.
