摘要
目的评价锥形束CT对牙槽骨线距测量的准确性与可靠性。方法通过检索多个数据库（PubMed，EBSCO，Scopus，Web of Science，中国期刊全文专题数据库CNKI及中国科技期刊数据库）获得相关文献。设定纳入标准为对人类牙槽骨的测量，并评价其测量的准确性和／或可靠性，对检索获得的文献进行进一步筛选。利用方法学评价表对纳入的文献进行评价。结果检索获得150篇文献，通过筛选共12篇文献纳入本系统综述。其中有8篇文章关注对牙槽骨厚度及／或高度的测量，4篇文章关注对牙槽骨缺损的测量。利用方法学评价表进行评价，仅有3篇文章的方法学质量较高，6篇文章方法学质量较低。锥形束CT对牙槽骨线距测量的准确性与可靠性较好，但应注意其有低估牙槽骨高度及厚度的趋势。CBCT测量与传统二维影像学检查的准确性有一定差异，当只有二维影像检查资料时，CBCT图像数据不宜纳入纵向比较。结论锥形束CT对牙槽骨线距测量的准确性与可靠性较好。
Objective To evaluate the accuracy and reliability of CBCT for linear measurement of alveolar bone. Methods Databases are searched, including PubMed, EBSCO, Scopus, Web of Science, CNKI and VIP. Inclusion criteria were studies on measurement on human alveolar bone and evaluation on measurement accuracy and/or reliability. The articles met the criteria were then furthermore screened and then evaluated by methodology table. Results 150 literatures were selected from the databases. After screening, 12 of them were included in this systemic review, 8 of which were about the measurement on alveolar bone thickness and height and 4 of them were about measurement of the alveolar bone defects. According to the methodology table, only 3 articles got relative high score on study methods and 6 articles got relative low score. The result showed that CBCT is acceptable for alveolar bone linear measurements for its good accuracy and reliability. It should be noticed that CBCT has a tendency to undervalue the height and width of alveolar bone. The accuracy comparison between CBCT measurement and conventional 2D measurement showed some extent of difference. Therefore, when provided only with 2D original image data, it is better not to use CBCT image for longitudinal comparison. Conclusions Linear measurement based on CBCT data on alveolar bone has relative good accuracy and reliability.
