“…, Vasconcelos et al . ). In addition, according to the SEDENTEXCT guidelines () and the ESE position statement (European Society of Endodontology ), 3D imaging for root fracture diagnosis should be indicated only if both clinical and conventional radiographic data do not provide adequate information for final diagnosis, which indicates that periapical radiography will remain being important for clinicians.…”

“…A high contrast resolution increases the availability of shades of gray in an image. Theoretically, this could improve diagnosis with more shades of gray in image until a limit considering the ability that the human eye can see and the contemporary computer monitors can support 15 . However, our results showed that spatial resolution seems to be more important than contrast resolution, as SnapShot exhibited better performance but lower contrast resolution when the aluminum wedge was evaluated.…”

Aim: To evaluate the performance of three digital radiographic systems in the analysis of root canal filling quality using different intracanal materials for primary teeth. Methods: Twenty-five bovine teeth were divided into 5 groups: Calen® combined with iodoform; Calen® combined with zinc oxide; zinc oxide and eugenol; UltraCal®XS, and 2% chlorhexidine combined with Ca(OH)2 + zinc oxide. Periapical radiographs were obtained with the VistaScan, Express, and SnapShot systems. The quality of the images was evaluated objectively (radiopacity) and subjectively (apical sealing and filling homogeneity). As the reference standard, the teeth were scanned with a micro-CT device. Results: Radiopacity differed among the radiographic systems and materials tested. In general, the greatest difference was observed between the Express and VistaScan systems; Calen® combined with iodoform resulted in the highest radiopacity. The radiographic systems did not differ in terms of homogeneity. However, Calen® combined with iodoform differed from the other materials and exhibited the best results. Regarding apical sealing, the SnapShot system and Calen® combined with zinc oxide provided the best results. Conclusion: Direct digital systems show better performance in evaluating the quality of endodontic treatment in primary teeth and should be preferred for this purpose.

“… 25 To detect the horizontal root fracture, intraoral radiography is widely used as it is cheap, has high resolution, and is convenient. 26 While interpreting radiographic images, a radiolucent line demonstrating discontinuity of dentine, which is not a shadow of the periodontal ligament, can be diagnostic of root fracture, 27 but subtle fissures in a very early stage without separation of the fragments may not be quantifiable by intraoral radiography. 28 The results of the study suggest that intraoral radiography is not an exact method for detection of horizontal root fracture.…”

“… 17 The effect of patient movement on the scans cannot be taken into account, which has a significant effect on the resolution of images 34 and also has the issue of root fillings or various types of post that affect diagnosis. 27 In respect to the selection of an object in the trial, the current study is first research on humans and provides valuable state-of-art research results in the field of Endodontists.…”

Background:Dental trauma is caused by fracture(s) in the vertical plane and the horizontal plane of roots. The objective of this study is to perform multiple diagnostic modalities for the diagnosis of horizontal root fracture(s) of the tooth.Methods:A total of 250 patients with dental complaints were subjected to intraoral radiography, multidetector helical computed tomography (MDHCT), and limited cone beam computed tomography (LCBCT). The suspected tooth was extracted, visually inspected, and subjected to microcomputed tomography (micro-CT). Images were observed in the lightbox, and a fracture was considered if it had been directly visualized as radiolucent line traversing tooth root. Wilcoxon test/Tukey post hoc test was performed at 99% of confidence level.Results:With respect to visual inspection, for LCBCT, intraoral radiography, MDHCT, and micro-CT, sensitivities were 0.988, 0.972, 0.967, and 0.979; accuracies were 0.956, 0.785, 0.905, and 0.888; false-positive values were 5, 21, 12, and 11; and false-negative values were 3, 24, 3, and 11, respectively. The area of the image visible at one time was in the order of treatment without radiography < intraoral radiography < MDHCT < micro-CT < LCBCT.Conclusion:The LCBCT had the highest sensitivity and accuracy for diagnosis of horizontal tooth root fracture(s).Level of Evidence:I.Trial Registry:researchregistry3647, dated December 31, 2016 (www.researchregistry.com).

Digital radiographs displayed on different devices: effect on the detection of vertical root fractures

Abstract: The type of display device did not affect the detection of VRFs. Thus, the detection of VRFs can be performed using different screen sizes and resolutions.
