Effect of surface conditioning on the shear bond strength of compomers to human primary and permanent enamel.

摘要: PURPOSE To compare the bond strength of two polyacid-modified composite resins (Compomer) to primary and permanent enamel with without acid-etching test for a possible relationship between determined shear values area cohesive failure within materials on bonding interface. MATERIALS AND METHODS Two compomer (Dyract Compoglass) their respective one-bottle primer/adhesive agents (Prime & Bond 2.0 Syntac Single Component) were investigated. The parameters tested type after debonding specimens respect total RESULTS Mean ranged from 4.09 MPa (Compoglass) 5.6 (Dyract), while in mean 12.3 14.3 when pretreatment was made only. Generally, prior improved adhesion significantly (6.0 8.1 16.0 19.4 Compoglass Dyract, respectively). Over one-half variation explained by its linear strength.
