| Summary: | DOI: 10.26650/eor.2018.449Purpose
The aims of this study were; to compare the
shear bond strength values of resin-based luting cements using etch-and-rinse,
self-etching or self-adhesive techniques and to evaluate the effects of
pretreatment with 0.2%, and 2% chlorhexidine (CHX) solutions on the bonding
stability to dentin.
Materials and methods
Ninety specimens were divided into 9 groups
of equal sample size (0.2% CHX, 2% CHX and no CHX application groups).
Variolink N (multi-step etch-and-rinse technique), Panavia F2.0 (self-etching
technique), or RelyX U200 (self-adhesive technique) resin-based luting cement
was applied. All specimens were subjected to shear bond strength test (SBS)
after bonding procedure. The mode of failure was analyzed by using a
stereomicroscope.
Results
There were no significant differences among
study groups for the dentin treatment factor. However, for luting cement
factor, significant differences were found and Variolink N showed the highest
SBS values.
Conclusion
CHX application has no immediate effect on
the SBS values of any resin cements. Despite the development of simplified
cementation techniques, etch-and-rinse technique is still the most reliable
technique because of its high bond strength to dentin. |
