3D Surface Profile and Color Stability of Tooth Colored Filling Materials after Bleaching

Table 4

Comparison of value of the tooth colored restorative materials after bleaching (between the bleaching agents).

Bleaching agent	Restorative material	Mean ± SD	value
Home bleaching; 20% CP	Filtek Z350 XT	2.2 ± 1.0	0.0001^*
	Estelite Σ Quick	3.7 ± 1.5
	Ketac N100	3.1 ± 1.2
In-office bleaching; 40% CP	Filtek Z350 XT	2.6 ± 1.1	0.0001^*
	Estelite Σ Quick	3.0 ± 1.2
	Ketac N100	2.7 ± 1.2

Mann-Whitney test; value < 0.05 is significant; CP: carbamide peroxide.
