The objective of this study was to review the experimental in vitro procedures employed to assess the color stability of resin-based composites exposed to smoke. A literature search was performed on four databases (Pubmed, Scopus, Embase, and Web of Science). The quality of the included papers was assessed with the Cochrane risk-of-bias tool (RoB 2). In total, 25 studies were selected for full-text reading, from which 12 were included in the review. The assessed variables were: dimensions, shape, time before exposure, finishing, smoke-type, exposure time, brushing simulation, color, measuring system, repolishing. A disk-shaped specimen was used in most studies (n=10) with a 2 mm thickness (n=7) in custom made devices equipped with vacuum pumps or in Vitrocell systems. Spectrophotometers were the most used devices (n=11). Color differences were quantified with ΔE (n=12), ΔE00 (n=1). The large variety of staining procedures suggests the need for standardization.
本研究的目的是回顾用于评估暴露于烟雾中的树脂基复合材料颜色稳定性的体外实验程序。在四个数据库（PubMed、Scopus、Embase和Web of Science）上进行了文献检索。使用Cochrane偏倚风险工具（RoB 2）评估纳入论文的质量。总共选择了25项研究进行全文阅读，其中12项纳入综述。评估的变量包括：尺寸、形状、暴露前时间、修整、烟雾类型、暴露时间、刷牙模拟、颜色、测量系统、再抛光。大多数研究（n=10）使用圆盘形试样，厚度为2 mm（n=7），置于配备真空泵的定制装置或体外细胞系统中。分光光度计是最常用的设备（n=11）。用ΔE（n=12）、ΔE00（n=1）对颜色差异进行量化。染色程序的多样性表明需要标准化。
