Abstract

Statement of Problem: BLOOD CONTAMINATION is a common problem in dentistry that can decrease bond strength dramatically which may be affected by methods of decontamination as well. Purpose: The aim of this study was to evaluate and compare the influence of BLOOD CONTAMINATION on SHEAR BOND STRENGTH of composite and COMPOMER to dentin using PROMPT L-POP as an adhesive system. Also, to assess the effectiveness of different surface treatments on the bond strength. Materials and Methods: In this experimental study, 120 molar teeth were sectioned to provide flat occlusal dentinal surfaces. Specimens were embedded in acrylic resin with the flat surface exposed. The dentinal expose surfaces were polished to 600 grit. The teeth were randomly divided into five groups of twelve specimens (F1–F5) for COMPOMER material and five other groups (Z1- Z5) for COMPOSITE RESIN. After application of Promt L-Pop to dentinal surfaces of specimens, the surfaces in all groups, except for F1 and Z1, (as controls) were contaminated with human blood and then one of the following surface treatments was applied. Groups F2 and Z2 without any treatment, groups F3 and Z3 rinsing with water, groups F4 and Z4 rinsing with water and reapplication of adhesive, groups F5 and Z5 rinsing with NaOCl and using PROMPT L-POP again. Restorative materials were applied to treated surfaces using plastic molds. After thermocycling, SHEAR BOND STRENGTHs, mode of failures and morphology of dentin-material interfaces were evaluated. The data were statistically analyzed using Factorial analysis of Variance, One-Way ANOVA, Duncan, T-student and Chi-Square tests with P<0.05 as the limit of significance. Results: COMPOMER showed statistically significant higher bond strength in comparison to composite (P<0.001). Duncan test showed significant differences between all COMPOMER groups, except between groups F4 and F5, and between all composite groups except for groups Z1 and Z4 and for groups Z2 and Z3. Conclusion: Based on the findings of this study, SHEAR BOND STRENGTH of COMPOMER material was significantly higher than composite. BLOOD CONTAMINATION reduced bond strength, but rinsing contaminated dentin with water or NaOCl and reusing PROMPT L-POP increased bond strength in both materials.
