title: A new cone beam computerized tomography system for use in endodontic surgery.
abstract: OBJECTIVE
  To present a newly developed cone beam computerized tomography system (3DX Micro-CT) and its application in endodontic surgery.
  
  
  CONCLUSIONS
  Cone beam CT has attracted considerable attention as a new diagnostic imaging technique in dentistry. The assessment of fractured endodontic instruments and the planning of endodontic surgery present challenges that conventional radiography cannot meet successfully. In this report, the value of the 3DX cone beam computerized radiography system is illustrated by the case of a fractured endodontic instrument protruding into the maxillary sinus.
