title: Localization of a displaced root fragment by stereoscopy and pluridirecitonal tomography.
abstract: The case reported describes two methods used with the Scanora integrated imaging system to locate a root fragment thought to be displaced into the maxillary sinus--rotational narrow beam stereoscopic scanning and wide angle cross-sectional pluridirectional tomography. While the stereo scans located the fragment within the sinus, a more accurate determination of its site, in relation to an object of known position, was obtained from the tomograms.
