The Performance of a Zirconium-based Root Filling Material with Artifact Reduction Properties in the Detection of Artificially Induced Root Fractures Using Cone-beam Computed Tomographic Imaging

Cone-beam Computed Tomographic–based Assessment of Filled C-shaped Canals: Artifact Expression of Cone-beam Computed Tomography as Opposed to Micro–computed Tomography and Nano–computed Tomography

“…Moreover, particularly for the acquisitions made using the NT, the high kVp may also have had an influence. These results corroborated findings in the literature that have demonstrated that the use of high kVp is associated with the production of more projection images, providing more information for the reconstruction process and thus improving overall image quality, which can reduce the expression of metal artifacts 1,3,4,6,7,10,11,14,19,20,[22][23][24][25][26] . However, it is worth emphasizing that the higher the number of projections, the longer the time of scanning, processing, and reconstruction, which could lead to the necessity of new acquisition because of motion artefacts 6,12,19,20,[25][26][27] .…”

“…A high kVp increases the average and maximum energy of the X-ray beam, leading to greater penetration capacity and reducing the beam hardening effect 6,7,19,20,[24][25][26][28][29][30][31] . However, it is worth mentioning that an increase in kVp or mA directly influences the amount of radiation dose to which the patient was exposed 19,20,24,29,30 .…”

“…For this reason, it cannot be expected that "endo" scanning protocols and metal artifact reduction modes improve the diagnostic image quality in the presence of endodontic restorations. For metal artifact reduction algorithms currently implemented in clinical CBCT imaging, several studies have shown little or no improvement in diagnostic efficacy [5][6][7]9 . Further studies are needed to explore the expression of endodontic artifacts and the different influencing factors at a fundamental level.…”

Evaluation of the efficacy of the metal artifact reduction algorithm in the detection of a vertical root fracture in endodontically treated teeth in cone-beam computed tomography images: An in vitro study

“…The majority of CBCT systems are capable of producing high-resolution images that visualize fine anatomical structures. 1,2 The advantages of CBCT compared to conventional radiography have increased its use in many dental fields. 3,4 The main advantage of CBCT in the detection of dental lesions is that it provides superior 3D images of the teeth and periodontal tissue compared to two-dimensional (2D) radiography.…”

Are metal artefact reduction algorithms effective to correct cone beam CT artefacts arising from the exomass?

“…[9][10][11][12] One of them is metal artefact reduction (MAR) that has been widely assessed for different diagnostic tasks when metallic objects are observed inside the FOV. [13][14][15][16][17] Importantly, the wide use of small FOVs in dentistry, associated with the presence of metallic materials, which are not always within the FOV, has raised a very common clinical condition to be investigated. Therefore, the aim of this study was to evaluate the effectiveness of MAR in CBCT when metallic objects are present in the exomass.…”
