对文献进行系统回顾，以评估锥形束计算机断层扫描(CBCT)作为测量牙周缺损牙槽骨丢失的工具的准确性程度。对PubMed电子数据库的系统搜索和对开放获取期刊的手工搜索(从2000年至2015年)产生了可能相关的摘要。然后检索原始文章，并手工搜索其参考文献，以寻找可能丢失的文章。只有符合选择标准的文章才会被纳入和批评。初步筛选出47篇潜在相关文章，其中只有14篇符合选择标准；其CBCT平均测量误差在0.19 mm到1.27 mm之间；然而，由于纳入研究之间的高度异质性，无法进行有效的荟萃分析。在现有研究数量和强度的限制下，我们得出的结论是，CBCT提供了牙周缺损区牙槽骨丢失的评估，最小报告平均测量误差为0.19±0.11 mm，最大报告平均测量误差为1.27±1.43 mm，并且无论是高估还是低估，两项研究对于偏差的方向没有一致的看法。然而，我们应该强调的是，这一数据的证据并不有力。
Systematic review of literature was made to assess the extent of accuracy of cone beam computed tomography (CBCT) as a tool for measurement of alveolar bone loss in periodontal defect. A systematic search of PubMed electronic database and a hand search of open access journals (from 2000 to 2015) yielded abstracts that were potentially relevant. The original articles were then retrieved and their references were hand searched for possible missing articles. Only articles that met the selection criteria were included and criticized. The initial screening revealed 47 potentially relevant articles, of which only 14 have met the selection criteria; their CBCT average measurements error ranged from 0.19 mm to 1.27 mm; however, no valid meta-analysis could be made due to the high heterogeneity between the included studies. Under the limitation of the number and strength of the available studies, we concluded that CBCT provides an assessment of alveolar bone loss in periodontal defect with a minimum reported mean measurements error of 0.19 ± 0.11 mm and a maximum reported mean measurements error of 1.27 ± 1.43 mm, and there is no agreement between the studies regarding the direction of the deviation whether over or underestimation. However, we should emphasize that the evidence to this data is not strong.
