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

Table 3

Comparison of between 3 different tooth colored restorative materials after bleaching (between restorative materials).

Restorative material	Bleaching agent	Mean ± SD	value
Filtek Z350 XT	20% CP HB	2.2 ± 1.02	0.0390^*
	40% CP OB	2.6 ± 1.1
Estelite Sigma Quick	20% CP HB	3.7 ± 1.5	0.0020^*
	40% CP OB	3.0 ± 1.2
Ketac N100	20% CP HB	3.1 ± 1.2	0.0160^*
	40% CP OB	2.7 ± 1.2

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