Title

EVALUATION OF SHEAR BOND STRENGTH OF TOTAL- AND SELF-ETCHING ADHESIVE SYSTEMS AFTER APPLICATION OF CHLORHEXIDINE TO DENTIN CONTAMINATED WITH A HEMOSTATIC AGENT

Pages

  175-181

Abstract

 Statement of the Problem: HEMOSTATIC AGENTs may influence the bond strength of different bonding agents. Also, CHLORHEXIDINE has shown positive effects on bond strength values and their combination effect has not been reported yet.Purpose: The aim of this study was to evaluate the effect of contamination with a HEMOSTATIC AGENT on SHEAR bond strength (SBS) of total- and SELF-ETCHING ADHESIVE systems and the effect of CHLORHEXIDINE application after removal of the HEMOSTATIC AGENT.Materials and Method: In this experimental study, the occlusal enamel of each sixty caries-free mandibular molars was removed and their midcoronal dentin was exposed. The specimens were then mounted in auto-polymerizing resin 1mm apical to CEJ. Then, the specimens were divided into 6 groups (n=10) based on contamination with a HEMOSTATIC AGENT (H), application of CHLORHEXIDINE (CHX) and the adhesive system used; and then were classified as Group 1: Adper Single Bond (ASB); Group 2: H+ASB; Group 3: H+0.2% CHX+ASB; Group 4: Clearfil SE Bond (CSB); Group 5: H+CSB; Group 6: H+0.2% CHX+CSB. Then, composite resin rods (4×2 mm) were built up on the dentin surfaces and after thermocycling, the SBS (MPa) was evaluated. Statistical analysis was performed using two-way ANOVA and post hoc Tukey tests (p< 0.05).Results: There were statistically significant differences between bond strength values of group 1 (ASB) and group 2 (H+ASB) (p< 0.001) and group 1 (ASB) and group 3 (H+CHX+ASB) (p<0.001). Similarly, significant differences were seen between group 4 (CSB) and group 5 (H+CSB) (p<0.001) and between group 4 (CSB) and group 6 (H+CHX+CSB) (p<0.001).Conclusion: Contamination with HEMOSTATIC AGENT reduced the SBS of both total- and SELF-ETCHING ADHESIVE systems. In addition, application of CHLORHEXIDINE after the removal of HEMOSTATIC AGENT had a negative effect on SBS of total- and SELF-ETCHING ADHESIVE systems.
