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

Table 2

Mean of push-out bond strengths (MPa).

Composite	Bond strengths (MPa)
Filtek Z350 XT	6.54 (0.94)^a
Filtek Z350 XT Flow	6.76 (1.53)^a
X-tra fil	5.12 (1.21)^b

Mean values followed by different lowercased letters in the column differed statistically by Student’s -test at 5% level for different composites. Standard deviations are given in parentheses.
