“…48 The 5 cases were interpreted with no bony separation in the CBCT images, on the other hand, 28 cases were also determined with no bony separation in the CBCT images, and therefore, the agreement between the presence of darkening of the roots in the PAN images and the absence of bone between the tooth and the mandibular canal was only 15.2%. 48 Recently, in one study, it was found that if interruption of the radiopaque borders of the canal and/or diversion of the canal and/or narrowing of the lumen of the canal was present in the PAN images, there was 1.6 times the probability that a direct contact was seen in the CBCT. 35 In summary, it seems that more of the seven signs for close contact to agreement, correlation between the methods; can, narrowing of the canal; dab, dark or bifid root; dark, darkening of the roots; defl, deflection of the roots; div, diversion of the canal; int, interruption of the radiopaque borders of the canal; PAN, panoramic imaging; ron, narrowing of the roots; SCAN, scanography; sens, sensitivity; SLOB, same lingual opposite buccal; spec, specificity.…”
