“…Interestingly, the specificity results were the opposite: the Post group presented with the highest specificity values among all groups, but with no significant association. Many previous studies [9][10][11]13,[15][16][17][18][19][20] have found higher values for sensitivity, specificity and accuracy for root fracture diagnosis, except for specificity of fracture in teeth filled up with metal posts (Table 4).…”

“…Numerous authors have evaluated the reliability and accuracy of CBCT images, considering different parameters, such as equipment, image resolution and artefacts. [8][9][10][11][12][13][14][15][16][17][18][19][20] None have addressed the possible influence software reconstruction may have on diagnostic accuracy. The present study evaluated the influence of software reconstruction of CBCT images in the diagnostic ability of experimentally induced vertical root fractures.…”

“…This extremely difficult diagnosis association (tenuous fracture line and artefacts) can also explain the intra-and interobserver intraclass correlation coefficient variation by reducing the observer's confidence at the time of diagnosis, leading to observers' agreement at even lower levels. 16,17 The level of agreement varies in research involving root fractures.

“…[4][5][6][7] Much research has been performed on the use of CBCT in the detection of root fractures, which remains a diagnostic challenge. [8][9][10][11][12][13][14][15][16][17][18][19][20] Although there is a low incidence of root fractures (approximately 0.5-10.1% in the permanent dentition), longitudinal fractures are increasingly common as a result of the greater longevity of patients, retention of more teeth and greater complexity of dental procedures. 8,21,22 Previous studies related to two-dimensional conventional analogue and digital intraoral radiography might well have underestimated the incidence.…”

“…These artefacts can severely compromise the result of CBCT examination. 8 In their study, Costa et al 9 noted that the presence of a metallic post in a canal significantly reduced the specificity and sensitivity of root fracture diagnosis. They stated that the artefacts produced by metallic posts had reduced the observer's confidence at the time of diagnosis, leading to levels of interobserver agreement ranging from no agreement to weak agreement.…”

Objectives: The aim of this CBCT investigation on the detection of caries was to assess the influence of artefacts produced by the presence of amalgam fillings located in the vicinity. Methods: 102 non-cavitated pre-molar and molar teeth were placed in blocks of silicone with approximal contacts consisting of 3 sound or carious teeth and 1 mesial-occlusal-distal amalgam-filled tooth in-between. Radiographs of all the teeth were recorded using the CBCT system (NewTomÔ 3G; QR Srl, Verona, Italy; field of view, 9 inches). Data from the CBCT unit were reconstructed and sectioned in the mesiodistal tooth plane. Images were evaluated twice by two observers, using a five-step confidence scale. After the CBCT examination, the teeth were individually sectioned in the mesiodistal direction with a diamond saw. Using a light microscope at 340 magnification, the true morphological status of all approximal surfaces was established. Results: Sensitivity of the CBCT for the detection of caries on surfaces located proximally and distally to an amalgam filing ranged from 0.27 to 0.30 for enamel and from 0.47 to 0.56 for dentin. Specificity values for enamel proximal and distal lesions were 0.48 and 0.53, respectively, for enamel and 0.33 to 0.38, respectively, for proximal and distal dentin cases. Intra-observer reliability was 0.84, and interobserver reliability was 0.49. Conclusions: Owing to its low specificity, scans from a CBCT examination should not be used to determine the presence of demineralization of the tooth surface when amalgam fillings are present in the region of interest.

The aim of this study was to evaluate the diagnostic ability of dental undergraduate students to detect horizontal and oblique root fractures (ORFs) using different imaging techniques. Materials and methods: Nine teeth were selected and randomly divided in three groups in order to create a fracture line without fragments separation: control (without fracture), horizontal root fracture (HRF), and ORF. The root fracture was created using perpendicular force and was confirmed by transillumination. A model with two adjacent teeth was created, and different imaging techniques were performed: conventional periapical radiograph; mesially and distally shifted periapical radiographs; cone-beam computer tomography (CBCT). Twenty students that had participation on dental trauma clinic at the year of 2019 were invited to identify root fractures by a five-point scale: (i) fracture definitely not present, (ii) fracture probably not present, (iii) uncertain whether fracture is present or not, (iv) fracture probably present, and (v) fracture definitely present. Data were analyzed by Kappa test for agreement evaluation. Results:Comparing each student to the gold standard, there was a variation in reproducibility and performance from poor to substantial (0.042-0.667). Reproducibility values ranged from poor to good for all periapical radiographs both in the diagnosis of ORF (−0.33-0.667) and in HRF (0-1). Conclusions: In CBCT images, the students' ability was lower in HRF detection in comparison with the oblique ones. The students showed limited capacity to diagnose root fractures; however when CBCT was used, the performance was more satisfactory than when periapical radiographs were used.
