Color match analysis of single-shade and multi-shade composite resins using spectrophotometric and visual methods after bleaching

The aim of this study is to evaluate the color match of the materials after the staining and bleaching procedures applied to the teeth restored with single-shade and multi-shade composite resins. Cavities prepared on the facial surface of human incisors were restored with two different composite resins. After 24 h, the color matching parameters between the initial filling-tooth of the samples were recorded. Then, the color measurements of the samples subjected to the coloring process were repeated. Each composite resin group was randomly divided into 2 subgroups and home and office bleaching methods were applied to the samples. After bleaching, color measurements were repeated. In terms of periods, a statistically significant difference was found in triangle E values 1 day and 28 days after bleaching (p < 0.05). In addition, it was found that the color match between filling-tooth was generally weaker in Omnichroma material and after home bleaching.
