“…CBCT currently renders the only radiographic method to visualize the bony contour on the buccal and lingual surfaces [ 14 ]. A common way to measure alveolar bone level is to measure the distance from a reference landmark such as cemento-enamel junction (CEJ) to alveolar bone crest with or without comparing with the root length [ 16 , 17 ]. Leung et al scanned 334 teeth from human dry skulls by CBCT and found that, with a 0.38 mm reconstructed isotropic voxel, the CEJ and alveolar bone height could be measured with an accuracy of 0.4 mm and 0.6 mm respectively as compared with direct measurement by a digital caliper [ 18 ].…”

Background and objectiveThe current methods to image alveolar bone in humans include intraoral 2D radiography and cone-beam computed tomography (CBCT). However, these methods expose the subject to ionizing radiation. Therefore, ultrasound imaging has been investigated as an alternative technique, as it is both non-invasive and free from ionizing radiation. In order to assess the validity and reliability of ultrasonography in visualizing alveolar bone, a systematic review was conducted comparing ultrasound imaging to CBCT for examination of the alveolar bone level.Study designSeven databases were searched. Studies addressing examination of alveolar bone level via CBCT and ultrasound were selected. Risk of bias under Cochrane guidelines was used as a methodological quality assessment tool.ResultsAll the four included studies were ex vivo studies that used porcine or human cadaver samples. The alveolar bone level was measured by the distance from the alveolar bone crest to certain landmarks such as cemento-enamel junction or gingival margin. The risk of bias was found as low. The mean difference between ultrasound and CBCT measurements ranged from 0.07 mm to 0.68 mm, equivalent to 1.6% - 8.8%.ConclusionsThere is currently preliminary evidence to support the use of ultrasonography as compared to CBCT for the examination of alveolar bone level. Further studies comparing ultrasound to gold standard methods would be necessary to help validate the accuracy of ultrasonography as a diagnostic technique in periodontal imaging.

“…The remaining six studies [6,36,[96][97][98][99] were found to be systematic reviews for which the AMSTAR-2 assessment tool [100] was used. It is a popular instrument modified from the original AMSTAR, which contains 16 checklist questions.…”

“…Each review is supposed to adhere to the criteria provided by AMSTAR and scores YES whenever applicable. The review published by Haas et al [96] did not elaborate on whether they included the study registries or consulted content experts in the field in terms of comprehensive literature search strategy. Although a metaanalysis was conducted in such a review, the review authors did not assess the potential impact of risk of bias on the results of the meta-analysis or other evidence synthesis.…”

Objectives The aim of this study was to address the diagnostic efficacy of cone beam computed tomographic (CBCT) imaging in periodontics based on a systematic search and analysis of the literature using the hierarchical efficacy model. Methods A systematic search of the electronic databases such as PubMed, Scopus, Web of Science, and Cochrane was conducted until February 2019 to identify studies addressing the efficacy of CBCT imaging in Periodontics. The identified studies were subjected to pre-identified inclusion criteria followed by an analysis using a hierarchical model of efficacy (model) designed for an appraisal of the literature on a diagnostic imaging modality. Two examiners performed the eligibility and quality assessment of relevant studies, and consensus was reached where disagreement was found. Results The search resulted in 64 studies. Of these, 35 publications were allocated to the relevant level of efficacy and quality assessments wherever applicable. The overall diagnostic accuracy studies showed the risk of bias and applicability concerns in the use of CBCT to be low to moderate. In addition, CBCT is accurate in identifying periodontal defects when compared to other modalities. The studies on the level of patient outcomes agreed that CBCT is a reliable tool for the assessment of the outcomes after the treatment of periodontal defects. Conclusion CBCT was found to be beneficial and accurate in cases of infra-bony defects and furcation involvements.
