Diagnostic validity (or acuity) of 2D CCD versus 3D CBCT-images for assessing periodontal breakdown.
196
TL;DR: CBCT images demonstrated more potential in the morphological description of periodontal bone defects, while the digital radiography provided more bone details, which may offer perspectives for further studies onperiodontal diagnostics, prognostics, and presurgical planning with CBCT.

Abstract: Objective The objective of this study was to compare 2-dimensional intraoral digital images with 3-dimensional cone beam CT (CBCT) in assessment of periodontal bone levels and defects. Methods Thirty periodontal bone defects of 2 adult human skulls (with soft tissue or substitute) were evaluated by using intraoral digital radiography and CBCT. Digital radiographs were made with a size #2 CCD sensor and a 60-kV DC x-ray unit, with 0.28, 0.42, or 0.56 mAs as respective exposure settings. For CBCT, jawbone images were obtained at 120 kV and 23.87 mAs. Periodontal bone levels and defects on both imaging modalities were assessed and compared to the gold standard. Delineation of lamina dura, crater defect, furcation involvements, contrast, and bone quality were also analyzed. Results Linear measurement deviations of periodontal bone levels from the gold standard ranged from 0.19 to 1.66 mm for intraoral radiography versus 0.13 to 1.67 mm for CBCT. Accuracy was not significantly different between both imaging modalities ( P = .161). Intraoral radiography scored significantly better for contrast, bone quality, and delineation of lamina dura, but CBCT was superior for assessing crater defects and furcation involvements ( P = .018). Conclusions CBCT images allowed comparable measurements of periodontal bone levels and defects as intraoral radiography. CBCT images demonstrated more potential in the morphological description of periodontal bone defects, while the digital radiography provided more bone details. These findings may offer perspectives for further studies on periodontal diagnostics, prognostics, and presurgical planning with CBCT.

A comparison of cone-beam computed tomography and direct measurement in the examination of the mandibular canal and adjacent structures.
TL;DR: Based on the results of this study, the I-CAT Classic can be used to measure distances from the apices of the posterior teeth to the mandibular canal as accurately as direct anatomic dissection.

Reliability of Circumferential Bone Level Assessment around Single Implants in Healed Ridges and Extraction Sockets Using Cone Beam CT
TL;DR: PA should be the standard technique to assess interproximal bone level but correlates poorly with the CBCT measurements, and there is an indication that the buccal bone 1 year after implant treatment is evenly preserved when implants are immediately loaded in extraction sockets or in healed bone.

Dosimetry of 3 CBCT devices for oral and maxillofacial radiology: CB Mercuray, NewTom 3G and i-CAT
TL;DR: CBCT dose varies substantially depending on the device, FOV and selected technique factors, and effective dose detriment is several to many times higher than conventional panoramic imaging and an order of magnitude or more less than reported doses for conventional CT.
