In addition, "none of the side canals, shown with FD-VCT, was detectable on conventional X-rays," test results revealed. "In all cases the enamel and dentin of the teeth could be well delineated. No differences in image quality could be discerned between stored and freshly extracted teeth, or between primary and adult teeth."

"FD-VCT is an innovative diagnostic modality in preclinical and experimental use for nondestructive 3-dimensional analysis of teeth. Thanks to the high isotropic spatial resolution compared with conventional X-rays, even the minutest structures, such as side canals, can be detected and evaluated," the researchers concluded. "Potential applications in endodontics include diagnostics and evaluation of all steps of root canal treatment, ranging from trepanation through determination of the length of the root canal to obturation."

Heidrich and colleagues published their study in Rofo - Fortschritte auf dem Gebiet der Rontgenstrahlen und der Bildgebenden Verfahren (Nondestructive, preclinical evaluation of root canal anatomy of human teeth with flat-panel detector volume CT (FD-VCT). Rofo, 2005;177(12):1683-1690).
