Bonding Performance for Repairs Using Bulk Fill and Conventional Methacrylate Composites

Table 2

Results of mean and standard deviation for the values of adhesive tensile strength and result of the Tukey’s test for interaction between factors for the aged bulk fill groups (OBFa).

Composite factor	12.95 (4.20) B		9.45 (3.84) A

Uppercase letters show differences in the line for each resin composite. Lowercase letters show differences in the column for each surface treatment. Significant statistical difference between the groups (two-way ANOVA test followed by the Tukey’s test, ).
