The tensile bond strength of resin-bonded, electrolytically etched alloy to enamel.

The tensile bond strength of two composite resin cements was evaluated using two different bonding procedures with each cement. There was no significant difference in tensile bond strength achieved by the two luting cements under the same test conditions (P > .05). Reducing the amount of bonding agent by gentle blowing significantly increased the tensile bond strength (P .05). Applying the bonding agent, without blowing, to both the enamel and metal surfaces prior to the application of the luting cement did not significantly increase the bond strength (P > .05). The fracture patterns observed were mostly a combination of adhesive and cohesive fractures.
