Push-Out Bond Strength of Restorations with Bulk-Fill, Flow, and Conventional Resin Composites

Table 3

Percentage (%) of failure mode.

Composite	Failure mode
	Cohesive	Adhesive	Mixed
Filtek Z350 XT	0 (0)	80 ()	20 ()
Filtek Z350 XT Flow	0 (0)	80 ()	20 ()
X-tra fil	0 (0)	90 ()	10 ()

The modes of failure were classified as follows: adhesive failure, cohesive failure within the composite, or mixed failure involving adhesive, dentin, and composite. The number of the specimens is given in parentheses.
