Abstract
Objective: The aim of this study was to evaluate the effect of powdered and powder-free latex gloves contamination on dentin bond strength of 2 step self-etch adhesive system.
Material and Method: Forty flat superficial dentin from human third molars were prepared and finished with 600-grit silicon carbide abrasive paper. The teeth were divided into 5 groups as follows: group 1-as a control, group 2 or 3-composite resin surfaces were contaminated by powdered latex dental gloves without or with wiping with 70% alcohol respectively, group 4 or 5 composite resin surfaces were contaminated by powder-free latex dental gloves without or with wiping with 70% alcohol respectively. Composite resins were filled-up on dentin surface bonded with a 2-step self-etch adhesive (ClearfilTM SE Bond), and then stored in 37°C water for 24 hours. After that the teeth were sectioned into beam-shape specimens at resin-dentin bond interface of 1x1 mm2 and subjected to microtensile bond strength test. Data were analyzed with one-way ANOVA and Tukey test (p<0.05). Failure mode was determined by using a stereomicroscope and SEM, and analyzed with Chi-square test (p<0.05).
Result: There were significant differences between control group (65.08 MPa) and 4 contaminated groups. The bond strengths of contaminated groups were significantly decreased in group 5 (58.01 MPa), group 3 (53.98 MPa), group 2 (52.64 MPa) and group 4 (49.41 MPa) (p<0.05), respectively.
Conclusion: Contamination from dental gloves decreased the bond strength between composite resin and dentin. Thus, operators should avoid touching or shaping composite resin by dental gloves even their surfaces were wiped with 70% alcohol.
