“…4 Limited CBCT (PSR 9000N; Asahi Roentgen Co., Kyoto, Japan) with 40 3 41 mm field of view (FOV) was more useful than multidetector helical computerized tomography at slice thicknesses of 0.63 mm and 1.25 mm for diagnostic imaging of horizontal tooth root fracture. 11 In a previous study, we found that limited FOV Accuitomo 80 CBCT unit (Morita, Tokyo, Japan) images obtained with a 4 3 4 cm FOV and 0.125 mm voxel size were significantly superior to intraoral images taken from different angulations in detecting HRF ex vivo. 7 Similarly, in another study, the diagnosis of the location and angulation of root fractures based on limited CBCT imaging differed significantly from diagnostic procedures based on intraoral radiographs alone.…”

Objectives: To compare limited cone beam computerized tomography (CBCT) units with different field of views (FOVs) and voxel sizes in detecting artificially created horizontal root fracture (HRF) in extracted human teeth. Methods: Artificial HRF was created in the horizontal plane in 40 teeth. Another 40 intact teeth served as a control group. 80 teeth were placed in the respective maxillary anterior sockets of a human dry skull in groups. Six image sets were obtained: (1)

“…[5][6][7][8][9] CBCT has been used for proper diagnosis of root fractures to overcome the inherent disadvantages of anatomic superimposition. 10 CBCT has allowed dental practitioners to visualize teeth three-dimensionally and with high spatial resolution. 11 While recent studies have demonstrated the superiority of CBCT in detecting root fractures, 1,3,4,6,[12][13][14][15] there are some limitations to proper imaging when high-density materials such as guttapercha and intracanal metal posts are present.…”

Objectives: To evaluate the influence of CBCT enhancement filters on the diagnosis of vertical root fractures (VRFs) in teeth with and without metal posts. Methods: The crowns of 40 uniradicular human teeth were removed and all roots were prepared. 20 teeth were randomly selected, and VRFs were induced using a universal testing machine. The i-CAT (Imaging Sciences International, Hatfield, PA) CBCT was used to scan teeth with and without intracanal metal posts using the following parameters: 0.2 voxel size, 8 3 8-cm scan size and acquisition time of 26.9 s. Images were evaluated by three observers with and without the use of the following filters: S9, smooth, smooth 3 3 3, sharpen, sharpenmild and sharpen 3 3 3. Results: Intra-and interobserver agreement ranged from poor to moderate. Images with and without CBCT filters did not show significant differences regarding the area under the receiver operating characteristic curve, as well as sensitivity (p . 0.05). As for accuracy, the sharpen-mild filter was superior to the sharpen (p 5 0.03), but these filters did not differ from all others. For specificity, S9, smooth and original images were superior to sharpen (p , 0.01). Results for teeth without posts differed from those for teeth with metal posts in all cases (p , 0.05). Conclusions: The use of enhancement filters in CBCT images has no influence on the diagnosis of VRFs in teeth with metal posts, and their use is not justified.

“…Using the ROC curve, the fracture diagnosis showed an accuracy of 0.73 and 0.74 with the Orthopantomograph OP300 ® and Orthophos XG 3D ® tomographs respectively, demonstrating that both examinations performed moderately. Other studies demonstrate more satisfactory results, such as the study by Hassan et al, 8 which confirmed good performance (0.86), and Iikubo et al, 22 with an accuracy rated as excellent (0.93). As far as the present study is concerned, the CBCT examination may be considered as just a complementary examination for diagnosis and indication of treatment planning when the existence of a dental root fracture is clinically suspected.…”

“…7,8,19,21 However, even with CBCT, visualizing the fracture line is difficult and a variety of factors influence the diagnosis. Iikubo et al, 22 in a study performed with dogs obtained significant results for CBCT efficiency in the diagnosis of root fracture, with a sensitivity of 0.6, specificity of 0.91, positive predictive value of 0.90, and a negative predictive value of 0.96. They concluded that this type of examination was the most reliable among the image acquisition modes studied (i.e., conventional intraoral radiography, helical computed tomography, and CBCT).…”

Aim: Our objective was to perform an in vitro evaluation of root fracture in endodontically treated teeth using two cone beam computed tomography (CBCT) machines. Materials and methods:The sample comprised 86 singlerooted human premolars that had been fractured by a universal testing machine. The tomographic images were acquired using an Orthopantomograph OP300 ® and an Orthophos XG 3D ® and evaluated by three examiners, by means of specific software. The teeth were classified into presence or absence of root fracture, then the root third where the fracture occurred, was determined. With regard to the detection of the fracture, the Kappa statistic was used for intra and interexaminer reproducibility at two distinct points in time. Chi-squared test was employed to analyze the sensitivity and specificity of the two tomographs (p < 0.05). Results:The results showed a good or excellent Kappa index between examiners. As for the absolute frequency, the sensitivity (0.6) of the Orthophos XG 3D ® equipment was superior, while specificity (0.91) was higher with the Orthopantomograph OP300 ® . On the receiver operating characteristics curve, moderate performance was found with an accuracy of 0.73 (OrthopantomographOP300 ® ) and 0.74 (Orthophos XG 3D ® ) respectively. As far as the location of the root fracture is concerned, moderate agreement was verified using the Kappa statistic (k = 0.56). Evaluation of Root Fracture in endodontically treated Clinical significance:An early and precise detection of root fractures is of the utmost clinical importance, but the radiopaque and/or metallic filling materials in the CBCT viewing field may generate artifacts, known as the beam-hardening effect, which could compromise root fracture detection.
