“…This section includes studies where implant fate evaluation was the main goal. Within this scope, understanding whether CBCT will detect these defects earlier than other imaging modalities and if these early detections will have an effect on the overall prognosis of the implants is a matter of current investigation 38‐43 …”

The current available literature reflects an increased optimization of emerging CBCT imaging protocols and further highlights its diverse applications for dental implant therapy. This technology continues to be considered an advanced point-of-care imaging modality and should be used selectively as an adjunct to two-dimensional dental radiography. As with other ionizing radiation imaging modalities, CBCT imaging should be used only when the potential benefits to the patient outweigh the risks. Dental health care professionals should consider CBCT imaging only when they expect the diagnostic information yielded will lead to better patient care, enhanced patient safety, and ultimately facilitate a more predictable, optimal treatment outcome.

“…The appropriate selection of CBCT acquisition parameters in the postoperative assessment of the images for diagnosis is important for determining image quality and the radiation dose 13. The selected FOV size, voxel thickness, number of frames, kVp, and mA can directly influence CBCT image quality, with implications for specific diagnoses 91327…”

“…The pellets were kept in contact with the bone for 2 hours. After each application, the mandibles were washed for 1 minute under tap water to remove all perchloric acid from the bone, according to a methodology used in previous studies 131718. Lesions up to one-third of the lingual-buccal distance of the second molar furcation19 were created to simulate incipient bone loss caused by periodontal disease at an early stage.…”

“…Endodontically treated teeth present intracanal metallic posts, and dental implants may produce artifacts in CBCT images 11. These artifacts are represented by radiopaque, radiolucent, and bright tracks that can overlap the teeth12 or bone and mimic bone loss 13. Previous studies have compared images in which metallic posts are present or absent,1112 different metallic post compositions,14 metallic and fiber posts,15 and PR or CBCT imaging for tooth fracture diagnosis 16.…”

Detection of furcation involvement using periapical radiography and 2 cone-beam computed tomography imaging protocols with and without a metallic post: An animal study

PurposeThe purpose of this study was to assess the accuracy, sensitivity, and specificity of the diagnosis of incipient furcation involvement with periapical radiography (PR) and 2 cone-beam computed tomography (CBCT) imaging protocols, and to test metal artifact interference.Materials and MethodsMandibular second molars in 10 macerated pig mandibles were divided into those that showed no furcation involvement and those with lesions in the furcation area. Exams using PR and 2 different CBCT imaging protocols were performed with and without a metallic post. Each image was analyzed twice by 2 observers who rated the absence or presence of furcation involvement according to a 5-point scale. Receiver operating characteristic (ROC) curves were used to evaluate the accuracy, sensitivity, and specificity of the observations.ResultsThe accuracy of the CBCT imaging protocols ranged from 67.5% to 82.5% in the images obtained with a metallic post and from 72.5% to 80% in those without a metallic post. The accuracy of PR ranged from 37.5% to 55% in the images with a metallic post and from 42.5% to 62.5% in those without a metallic post. The area under the ROC curve values for the CBCT imaging protocols ranged from 0.813 to 0.802, and for PR ranged from 0.503 to 0.448.ConclusionBoth CBCT imaging protocols showed higher accuracy, sensitivity, and specificity than PR in the detection of incipient furcation involvement. Based on these results, CBCT may be considered a reliable tool for detecting incipient furcation involvement following a clinical periodontal exam, even in the presence of a metallic post.

Effect of Cone‐Beam Computed Tomography Field of View and Acquisition Frame on the Detection of Chemically Simulated Peri‐Implant Bone Loss In Vitro

Abstract: Within the limits of this study, optimal detection of chemically simulated pericircumferential implant crestal bone defects is achieved at the least radiation detriment using the smallest FOV, the highest number of acquisition frames, and the smallest voxel.
