Endoscope--an endodontic application

The endoscope utilized by otolaryngologists for the past 10 yr has a place in the armamentarium of the endodontist as well. It provides improved visualization of root apicies, especially those not in the line of direct vision. It can illuminate and identify roots in the sinus if such treatment becomes necessary. By allowing a magnified view of the root-end preparation before and after placement of the filling material, any fractures or extraneous material can be identified. This instrument is quite small and readily transportable from one operatory to another. The cost is a fraction of the price of the surgical microscope.
