Zur Wertigkeit der hochauflösenden Computertomographie (HRCT) bei der Diagnostik profunder Parodontitisformen

: It is difficult to demonstrate the extent of parodontal bone erosions with conventional radiographic techniques. HRCT makes it possible to demonstrate the alveolar structures without superimposition. 10 patients with parodontitis marginalis profunda were examined by conventional methods and HRCT. Comparison showed considerable superiority of HRCT in respect of demonstrating bone destruction. The absence of superimposition produces excellent demonstration of the roots and shows the bifurcation and trifurcation of teeth; consequently, mapping the position and shape of the root canals is possible and this is an important aid in the planning of parodontal surgical treatment.
