Can Fiber Application Affect the Fracture Strength of Endodontically Treated Teeth Restored with a Low Viscosity Bulk-Fill Composite?

Table 2

Mean fracture resistance of the groups and statistical differences among them.

Groups	Thermo-mechanical Aging - (TMA)	Thermo-mechanical Aging + (TMA)
	Mean±SD; (Newton)	Mean±SD; (Newton
Group IN	1351.4 (238.8)	1210.1 (318.5)
Group BF	736.8 (116.4)	788.7 (210.5)
Group PRF1	818.9 (166.1)	803.3 (78.1)
Group PRF2	821.9 (226.3)	832 (209.2)

Superscripts show the significant difference between the groups, while lower cases show the significant difference of columns (p<0.005). SD=standard deviation.
