Influence of adjacent teeth restored with metal posts in the detection of simulated internal root resorption using CBCT

Abstract: AimTo assess the influence of artefacts generated by metal posts on the detection of simulated internal root resorption (IRR) in adjacent teeth using cone‐beam computed tomography (CBCT) and to verify the impact of metal artefact reduction (MAR) on these cases.MethodologyCBCT images of 14 premolar teeth were acquired before and after IRR simulation using chemical and mechanical procedures, in an OP300 Maxio unit, with and without MAR. Each tooth was placed in the socket of a human mandible and scanned under th… Show more

“…However, despite these advantages, image artifacts can occur when high-density materials are present in the scanned area, which is often the case with dental materials [13,18,19]. Strategies to reduce the expression of image artifacts have been well-described in the scienti c literature, with some proving successfully while others have not [6,7,12,[20][21][22][23][24]. In this experimental study, we tested the modi cation of the spatial orientation of the head in an endeavour to avoid image artifacts in the vicinity of a dental implant and, interestingly, observed higher mean voxel values in all cases and, in most cases, lower noise values in the anterior and posterior regions of a dental implant.…”

“…This misdiagnosis can have a signi cant negative impact, potentially resulting in the unnecessary extraction of a tooth. Furthermore, the presence of artifacts generated by teeth restored with a metal post also negatively in uenced the diagnosis of internal root resorption in adjacent teeth [7].…”

“…Research regarding the impact of artifacts on diagnostic procedures is widely available in the dental literature. 3 4 5 6 7 8 9 10 11 These studies have primarily focused on the influence of intracanal materials and the presence of dental implants in the oral cavity. 9 10 11 Regarding the assessment of artifacts on the identification of carious lesions, previous studies have typically utilized direct restorations 3 4 or orthodontic materials 8 as the artifact sources or have simulated artificial caries lesions.…”

“… 3 4 5 7 8 Several studies have investigated the impact of artifacts on the diagnosis of various conditions - such as vertical root fractures, internal and external root resorption, and proximal caries lesion - when these conditions are positioned adjacent to high-density materials, including dental implants, endodontic fillings, and restorative materials. 3 4 5 6 9 10 11 …”
