Objectives:
The aim of this study was to examine the effect of carbamide
peroxide bleaching gel containing remineralization agents on the bond strength
of universal adhesives to enamel.
Materials & Methods:
135 extracted human third molars were divided into
five groups to receive treatments during 14 days, as follows: no bleaching
treatment; 10% carbamide peroxide (CP); 10% CP containing 0.11% fluoride;
10% CP containing casein phosphopeptide-amorphous calcium phosphate
(CPP-ACP); and 10% CP containing CPP-ACP and 0.11% fluoride. The buccal
surfaces of all teeth were etched with 37% phosphoric acid, and each group
was divided into three subgroups to receive the adhesive resins: All bond
universal; Scotchbond Universal and Adper Single Bond 2. Then restored teeth
were sectioned to create resin-enamel beams. These beams were subjected
to the micro-tensile bond strength (µTBS) test, and assessed for failure mode
under scanning electron microscopy.
Results:
The highestmeanµTBSof the composite resin to enamel was observed
in the control group (25.9 MPa) and the lowest in the fluoride-containing
bleaching group (17.2 MPa). Adper Single Bond 2 adhesive subgroups have
the highest µTBS (19.7 MPa) and All Bond Universal adhesive subgroups have
the lowest µTBS (16.8 MPa).
Conclusion:
The carbamide peroxide bleaching gel containing a remineralizing
agent decreased µTBS. Delay for at least two weeks after the end of bleaching
would minimize the presence of remaining oxygen that could negatively
impact resin polymerization. In addition, using fluoride-containing bleaching
materials should be avoided to reduce the loss of bond strength.
