Depth determination of artificial periodontal pockets using cone-beam tomography and radio-opaque material: an in vitro feasibility study


Weidmann, Benjamin; Sahrmann, Philipp; Bindl, Andreas; Roos, Malgorzata; Schmidlin, Patrick R (2014). Depth determination of artificial periodontal pockets using cone-beam tomography and radio-opaque material: an in vitro feasibility study. Swiss Dental Journal, 124(4):406-415.

Abstract

In general, periodontal tissues are clinically assessed using calibrated periodontal probes and radiographs. Due to technical developments and the availability of cone-beam computed tomography (CBCT), 3-D imaging has become feasible and offers some advantages and potential for the evaluation of complex anatomical structures. The present pilot study illustrates and validates the possibility of radiographically visualizing and metrically assessing hard and soft tissue. Artificial periodontal pockets were created in porcine mandibles and measured by clinical (i.e. pocket probing) and radiographic means (CBCT). For the latter method, pockets were filled with a radiopaque material allowing visualization by CBCT. Clinically simulated pocket depth probing and CBCT measurements were compared. The results showed no statistically significant differences between the two methods. Thus, the CBCT visualization approach points towards the development of a new and promising radiographic all- in-one evaluation system of the periodontal status. However, more research and development is required.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
