Periodontal diseases are prevalent among adult populations. Its diagnosis depends mainly on clinical findings supported by radiographic examinations. In previous decades, cone beam computed tomography has been introduced to the dental field. 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.
A systematic search of electronic databases such as PubMed, Scopus, Web of Science, and Cochrane was conducted in 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 diagnostic imaging modality. Four examiners performed the eligibility and quality assessment of relevant studies and consensus was reached in cases where disagreement occurred.
The search resulted in 64 studies. Of these, 34 publications were allocated to the relevant level of efficacy and quality assessments wherever applicable. The overall diagnostic accuracy of the included studies showed a low or moderate risk of bias and applicability concerns in the use of CBCT. 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 outcomes after the treatment of periodontal defects.
CBCT was found to be beneficial and accurate in cases of infra-bony defects and furcation involvements.
牙周病在成年人群中普遍存在。其诊断主要依赖于临床发现，并辅以影像学检查。在过去几十年中，锥形束 CT 已被引入牙科领域。本研究旨在通过系统检索文献并使用分层疗效模型进行分析，评估锥形束 CT（CBCT）成像在牙周病学中的诊断效能。
2019 年 2 月，我们对电子数据库（如 PubMed、Scopus、Web of Science 和 Cochrane）进行了系统检索，以确定评估 CBCT 成像在牙周病学中应用的研究。对确定的研究进行了预先确定的纳入标准筛选，然后使用专门设计用于评估诊断影像学方法文献的分层疗效模型（模型）进行分析。四名检查者对相关研究的合格性和质量进行了评估，如果存在分歧，则达成共识。
检索结果共 64 项研究。其中，34 篇出版物在适用的情况下被分配到相关的疗效和质量评估水平。纳入研究的总体诊断准确性显示，在使用 CBCT 时存在低或中度偏倚风险和应用问题。此外，与其他影像学方法相比，CBCT 能更准确地识别牙周缺损。关于患者结局的研究一致认为，CBCT 是评估牙周缺损治疗后结局的可靠工具。
CBCT 在诊断骨下缺损和分叉受累方面是有益且准确的。
