This systematic review and meta-analysis compared the accuracy of intraoral scanners and spectrophotometers in determining tooth shade.
An electronic search of five databases (PubMed, Scopus, Embase, Web of Science, CENTRAL) was conducted on October 19, 2023. A total of 163 studies were identified from the databases, of which 23 articles were eligible for inclusion. In vivo and in vitro quasi-experimental studies were included. After data extraction, a quantitative analysis was performed to determine the accuracy of the intraoral scanner in subgroups using four outcomes: trueness and precision with different measurement locations. A random-effects model was used to pool effect sizes. The pooled proportion with a 95% confidence interval (CI) was used for the effect size measure.
Eleven articles were included in the meta-analysis. Trueness with the intraoral scanner was between 0.28 (CI: 0.09-0.60) and 0.38 (CI: 0.24-0.53). Repeatability was between 0.81 (CI: 0.64-0.91) and 0.85 (CI: 0.74-0.92). Trueness showed low, and precision had moderate certainty of evidence.
The trueness of shade matching with intraoral scanners is low compared to spectrophotometers, although the precision is considered high and is similar to spectrophotometers.
Shade determination with intraoral scanners is not recommended.
本系统评价和荟萃分析比较了口腔内扫描仪和分光光度计在确定牙齿颜色方面的准确性。
于2023年10月19日对五个数据库（PubMed、Scopus、Embase、Web of Science、CENTRAL）进行电子检索。从数据库中总共识别出163项研究，其中23篇文章符合纳入标准。纳入体内和体外准实验研究。数据提取后，进行定量分析以确定口腔内扫描仪在亚组中的准确性，使用四个结果：不同测量位置的准确性和精密度。采用随机效应模型合并效应量。效应量测量采用95%置信区间（CI）的合并比例。
荟萃分析纳入11篇文章。口腔内扫描仪的准确性在0.28（CI：0.09 - 0.60）至0.38（CI：0.24 - 0.53）之间。重复性在0.81（CI：0.64 - 0.91）至0.85（CI：0.74 - 0.92）之间。准确性显示证据确定性低，精密度显示证据确定性中等。
与分光光度计相比，口腔内扫描仪在颜色匹配方面的准确性较低，尽管其精密度被认为较高且与分光光度计相似。
不建议使用口腔内扫描仪进行颜色测定。
