Title

COMPARISON OF DENTIN MICROSHEAR BOND STRENGTH OF CHLORHEXIDINE ON TWO STEP SELF-ETCH ADHESIVES WITH AND WITHOUT FLUORIDE AFTER 6-MONTH STORAGE IN WATER

Pages

  261-270

Abstract

 Background and Objective: Regarding the possible leakage of the bacteria in the cavity; the use of antibacterial agents such as CHLORHEXIDINE in the adhesive restorations has been proposed.However, the effect of this process on the long-term bond strength to the dentin has not been studied completely. This study assessed the effects of CHLORHEXIDINE on the dentine MICRO-SHEAR BOND STRENGTH of two-stage SELF-ETCH ADHESIVES with and without FLUORIDE after 6-month storage in water.Subjects and Methods: In this in vitro study, 40 extracted human mandibular third molars were obtained and after dentin exposure and polishing with silicone carbide for standard smear layer preparation; they were assigned into 4 groups. With or without using CHLORHEXIDINE adhesives of Clearfil SE Bond and Clearfil Liner Bond F were applied to the dentin surface and the teeth were restored with Z250 composite. The teeth were incubated for 6 months at 37oC temperature and 100% moisture and received 1000 thermal cycles. The micro shear bond strength of the specimens was determined and their fracture patterns were determined by streomicroscope. The data were analyzed by one-sided analysis of variances test while the paired comparisons were done by Tukey test.Results: Application of CHLORHEXIDINE at dentin surface since performing by adhesive sel-fetch did not cause any seriouse adverse effects on bond strength. Mean±standard deviation of the bond strength values with and without the application of CHLORHEXIDINE for the Clearfil SE Bond were 20.66±3.27 and17.48±7.11 MPa. The figures were 31.63±7.33 and 31.42±11.39 MPa for Clearfil Liner Bond F adhesive (P>0.05).Conclusion: Because of antibaterial effect of CHLORHEXIDINE and having no negative effect on bond strength; surface preparation with this agent beside using FLUORIDE-containing adhesives is suggested to eradicate the existing bacteria and decreases microleakage in the clinical condition without compromising bond strerngth.
