Kinetics of Conversion of Two Dual-cured Adhesive Systems

Activation Mode Effects on the Shear Bond Strength of Dual-cured Resin Cements

“…However, this adhesive system presents solvents (acetone) in a composition that can reduce its cohesive strength. 21 In addition, the use of a catalyst self-cure activator improves the solvent's ratio, reducing the degree of conversion of the adhesive, 22 and further compromising its mechanical properties (Figure 3). This can explain the intermediate values of shear bond strength presented by Enforce.…”

Contemporary Methacrylate Resin–based Root Canal Sealers Exhibit Different Degrees of Ex Vivo Cytotoxicity When Cured in Their Self-cured Mode

“…Recently, self-adhesive (ie, self-etching) versions of these sealers have been introduced that eliminate the use of a separate priming step (16,17), rendering them easier and faster to use. Although resin composites may show acceptable biocompatibility when polymerized under optimal light-curing conditions (18,19), the cytotoxicity of dualcurable resin-based sealer composites should be evaluated in the self-cured mode (20,21) because this is how the sealers polymerize in the apical third of canal walls and within the periradicular tissues (22). Casual interpretation of the cytotoxicity results of sealer composites polymerized under different/undefined curing conditions may lead to erroneous conclusions (23).…”

Restoration of Root Canal-Treated Teeth

“…However, these materials also depend on light curing to reach a high degree of conversion (Faria-e-Silva et al 2008 ).…”

“…8.8d ). Even if using a dual-cure twostep adhesive, perform the light-curing step, because these materials do not polymerize well without light curing (Faria-e-Silva et al 2008 ;Thitthaweerat et al 2012 ).…”
