Influence of Immediate Dentin Sealing on the Shear Bond Strength of Pressed Ceramic Luted to Dentin with Self-Etch Resin Cement

Table 3

Shear bond strength (MPa) ± SD of groups A to E/modes of failure.

Groups with the same superscript number in the same columns are not significantly different (𝑃>0.05).
Groups with a different superscript letter in the same column are significantly different (𝑃<0.05).
Mode failure 1: adhesive failure at the ceramic-cement interface, Mode failure 2: adhesive failure at the bonding surface-cement interface, Mode failure 3: cohesive failure within the cement or Mode failure 4: mixed failure (any combination of the first three modes).
