Effect of 10 percent carbamide peroxide on color of provisional restoration materials.
To improve esthetic results, nightguard vital bleaching of teeth using 10 percent carbamide peroxide, or CP, may be indicated when an anterior tooth is restored with a provisional crown. This study evaluated the effect of NGVB solutions containing 10 percent CP on the color stability of provisional restoration materials. Disks were fabricated from six representative provisional restoration materials and were tested in five different 10 percent CP bleaching agents. An orange discoloration occurred with provisional materials that contained methacrylate when they were exposed to 10 percent CP bleaching solutions.
