Rubber dams are frequently used to enable clinicians to achieve better visualization and isolation for dental procedures. Growing in popularity thanks in part to an increasing number of techniques facilitating their placement, rubber dams are able to be used for myriad restorative procedures, including crown and veneer preparation and cementation. An effect of rubber dam use is reduction of saliva, which causes temporary dehydration of the isolated teeth. In turn, this dehydration affects shade matching, an important aspect of esthetic outcomes. The purpose of this study was to determine the extent that shade is altered from baseline due to dehydration from rubber dam use during restorative procedures, and, furthermore, to determine the length of time required for teeth to rehydrate back to their baseline shade.
橡皮障常用于帮助临床医生在牙科操作中获得更好的可视化和隔离效果。由于越来越多的技术可以帮助其放置，橡皮障的使用变得越来越流行，它们可以用于众多修复程序，包括牙冠和贴面的预备和粘结。橡皮障使用的一个效果是减少唾液，这会导致隔离牙齿暂时脱水。反过来，这种脱水会影响颜色匹配，这是美学效果的一个重要方面。本研究的目的是确定由于修复过程中使用橡皮障导致的脱水，从基线开始颜色会改变多少，并进一步确定牙齿重新水化回基线颜色所需的时间。
