“…However, the higher radiation exposure cannot always be justified. 4 Considering the various benefits, CBCT is currently being evaluated as a superior diagnostic tool for applications in periodontology. 5 CBCT scans produce reconstructed multiplanar images that allow the clinician to three dimensionally assess the area of interest, 6 resulting in more accurate diagnoses that should improve patient management.…”

Objectives: This study assessed the influence of different voxel resolutions of two different CBCT units on the in vitro detection of periodontal defects. Methods: The study used 12 dry skulls with a maxilla and a mandible. Artificial defects (dehiscence, tunnel, fenestration) were separately created on the anterior, premolar and molar teeth using burrs. A total of 14 dehiscences, 13 fenestrations, 8 tunnels and 16 non-defect controls were used in the study. Images were obtained from two different CBCT units in six voxel sizes (voxel size: 0.080, 0.100, 0.125, 0.150, 0.160 and 0.200 mm 3 ). Kappa coefficients were calculated to assess both intra-and interobserver agreements for each image set. Results: Overall intraobserver kappa coefficients ranged between 0.978 and 0.973 for the 0.080-mm 3 images and between 0.751 and 0.737 for the 0.160-mm 3 images, suggesting notably high intraobserver agreement for detecting periodontal defects. CBCT performed significantly better at detecting fenestrations (p , 0.05) than tunnel and dehiscence defects. No statistically significant difference was found between the detection of dehiscence and tunnel defects (p . 0.05). Conclusions: A voxel size of 0.150 mm 3 was identified as the cut-off point for overall detection of periodontal defects. CBCT should be considered the most reliable imaging modality for the diagnosis of periodontal defects.

“…Cone beam computed tomography (CBCT) is a volumetric acquisition technique providing accurate and reliable sub-millimeter resolution images in all spatial dimensions. [6][7][8] CBCT may play a role in the assessment of marginal bone contours and three-dimensional defects, especially furcations and infrabony defects, in which defect morphology directly influences treatment planning and prognosis. 9,10 M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT 5 Voxel size is of paramount importance in terms of quality and scanning and reconstruction times of CBCT images.…”

“…These results reflect the limitations of 2-dimensional exams. Bone defects and furcation involvement are usually better depicted with CBCT imaging than with PR 26. Bone lesion observation with a PR image of 2-rooted or 3-rooted teeth is complicated, since an eventual superimposition of anatomic structures27 and the thickness of cortical bone can influence the visualization of the images 28…”

PurposeThe purpose of this study was to assess the accuracy, sensitivity, and specificity of the diagnosis of incipient furcation involvement with periapical radiography (PR) and 2 cone-beam computed tomography (CBCT) imaging protocols, and to test metal artifact interference.Materials and MethodsMandibular second molars in 10 macerated pig mandibles were divided into those that showed no furcation involvement and those with lesions in the furcation area. Exams using PR and 2 different CBCT imaging protocols were performed with and without a metallic post. Each image was analyzed twice by 2 observers who rated the absence or presence of furcation involvement according to a 5-point scale. Receiver operating characteristic (ROC) curves were used to evaluate the accuracy, sensitivity, and specificity of the observations.ResultsThe accuracy of the CBCT imaging protocols ranged from 67.5% to 82.5% in the images obtained with a metallic post and from 72.5% to 80% in those without a metallic post. The accuracy of PR ranged from 37.5% to 55% in the images with a metallic post and from 42.5% to 62.5% in those without a metallic post. The area under the ROC curve values for the CBCT imaging protocols ranged from 0.813 to 0.802, and for PR ranged from 0.503 to 0.448.ConclusionBoth CBCT imaging protocols showed higher accuracy, sensitivity, and specificity than PR in the detection of incipient furcation involvement. Based on these results, CBCT may be considered a reliable tool for detecting incipient furcation involvement following a clinical periodontal exam, even in the presence of a metallic post.
