title: A method for retrieving endodontic or atypical nonendodontic separated instruments from the root canal: a report of two cases.
abstract: OBJECTIVE
  This clinical report presents a new method for retrieving separated instruments from the root canal with minimally invasive procedures.
  
  
  BACKGROUND
  The presence of separated instrument in root canal may interfere in the endodontic treatment prognosis. There are several recommended methods to retrieve separated instruments, but some are difficult in clinically practice.
  
  
  METHODS
  This study describes two cases of separated instrument removal from the root canal using a stainless-steel prepared needle associated with a K-file. Case 1 presented a fractured gutta-percha condenser within the mandibular second premolar, it was separated during incorrect intracanal medication calcium hydroxide placement. Case 2 had a fractured sewing needle within the upper central incisor that the patient used to remove food debris from the root canal. After cervical preparation, the fractured instruments were fitted inside a prepared needle and then an endodontic instrument (#25 K-file) was adapted with clockwise turning motion between the needle inner wall and the fragment.
  
  
  CONCLUSIONS
  The endodontic or atypical nonendodontic separated instrument may be easily pull on of the root canal using a single and low cost device.
  
  
  CONCLUSIONS
  The methods for retrieving separated instruments from root canal are difficult and destructive procedures. The present case describes a simple method to solve this problem.
