Abstract
Iatrogenic root perforation is a procedural error that complicates treatment and can lead to loss of the tooth. A number of new instruments and techniques have been introduced into endodontic practice over the last few years to address this problem. The recent addition of the operating microscope to improve the field of vision has provided the operator with the benefit of magnification and enhanced illumination. Although there are few studies evaluating objectively the use of the operating microscope, its clinical application demonstrates the possibility of achieving more precise endodontic practice. The use of the operating microscope in the non-surgical management of a mid-root perforation is reported in this paper.
