Abstract
An endoscope for use in endodontics was developed and tested on three patients. The 0.91-mm diameter needle probe houses an optical system of three lenses and a fiber optic bundle surrounded by illumination fibers. This probe was inserted into instrumented root canals for either viewing or photography. Some blurring of photographs because of quarter-to-half second exposure times necessitated a higher speed film system. The endoscope can be used for a variety of diagnostic and research procedures and is capable of magnification of approximately X20.
