The variation in findings with regards to the accuracy and precision of intraoral scanners for shade selection are no doubt confusing for clinicians who may find it difficult to make evidence-based decisions. The aim of this systematic review is to provide a comprehensive and in-depth assessment of available studies to determine the viability of using intraoral scanners for the purpose of shade matching. The PICO-guided research question is as follows: when shade matching, are intraoral scanners as valid as visual or other digital shade measuring devices in determining tooth colors.
Electronic databases including PubMed/MEDLINE, SCOPUS, EBSCO, Cochrane, and ProQuest were systematically searched for articles published between January 1, 2011 and December 30, 2021 using the main search terms: "intraoral scanners," "scanners," "TRIOS," "CEREC," "Planmeca," "Medit," "digital dentistry" in concurrence with one of the following keywords: "EasyShade" OR "shade selection" OR "shade matching" OR "shade" OR "tooth color" OR "tooth shade" OR "digital shade matching." Bibliographies of included articles and the following journals were searched for relevant articles: Journal of Prosthetic Dentistry, Journal of Prosthodontics, Journal of Esthetic and Restorative Dentistry, Journal of Advanced Prosthodontics, and Journal of Dentistry. A total of 15 articles were included in the review.
Intraoral scanners are highly repeatable for shade matching, and outperformed visual shade matching. Accuracy varied significantly between studies, with the majority recommending the use of visual shade matching to confirm/verify the intraoral scanner results. Setting intraoral scanners to the Vita 3D Master shade guide improved both accuracy and precision. Shade matching with intraoral scanners may be influenced by external factors such as ambient light sources and incorrect use or manipulation.
Intraoral scanners set to the Vita 3D Master shade guide may be used for shade matching, but shade should be verified with visual shade matching. Further studies are required to address limitations of current studies.
口腔内扫描仪在比色准确性和精密度方面的研究结果差异无疑让临床医生感到困惑，他们可能难以做出基于证据的决策。本系统评价的目的是对现有研究进行全面深入的评估，以确定使用口腔内扫描仪进行比色的可行性。基于PICO的研究问题如下：在比色时，口腔内扫描仪在确定牙齿颜色方面是否与视觉或其他数字比色设备一样有效。
使用主要检索词“口腔内扫描仪”“扫描仪”“TRIOS”“CEREC”“普兰梅卡”“美迪特”“数字牙科”，并与以下关键词之一同时检索电子数据库，包括PubMed/MEDLINE、SCOPUS、EBSCO、Cochrane和ProQuest，检索2011年1月1日至2021年12月30日发表的文章：“EasyShade”或“比色选择”或“比色匹配”或“色度”或“牙齿颜色”或“牙齿色度”或“数字比色匹配”。对纳入文章的参考文献以及以下期刊进行检索以查找相关文章：《口腔修复学杂志》《口腔修复学》《美学与修复牙科杂志》《高级口腔修复学杂志》和《牙科杂志》。本评价共纳入15篇文章。
口腔内扫描仪在比色方面具有高度可重复性，并且优于视觉比色。不同研究之间的准确性差异显著，大多数研究建议使用视觉比色来确认/验证口腔内扫描仪的结果。将口腔内扫描仪设置为Vita 3D Master比色板可提高准确性和精密度。使用口腔内扫描仪进行比色可能会受到外部因素的影响，如环境光源以及不正确的使用或操作。
设置为Vita 3D Master比色板的口腔内扫描仪可用于比色，但应通过视觉比色进行验证。需要进一步研究以解决当前研究的局限性。
