Comparison of Measurements on Cone Beam Computed Tomography for Periodontal Intrabony Defect with Intra-surgical Measurements.

Abstract

CBCT could provide relatively accurate measurements of the M-D width of the defect and additionally showed accurate measurements of the B-L width of the defect which periapical radiographs could not show. However, for vertical measurements of the intrabony defect (CEJ to BD and depth of the defect), when compared with measurements during the surgery, CBCT showed no advantages over periapical radiographs. A new method should be developed for accurately measuring the periodontal intrabony defects using CBCT in the future.
