The aim of the present study was to determine if ZO-E affects shear bond strength. Methods: For the purposes of the study, extracted human molar teeth were ground so thatcomposite rods could be bonded to dentine. In group 1, dentine was not exposed to ZO-E. In group 2, ZO-E was applied to dentine for 10 days prior to acid etching and bonding the composite. A universal testing machine was used to determine the composite’s shear bond strength. Data were analyzed using t-test. Results: Mean score of shear bond strengths were 137.15 (± 46.82) and 140.08 (± 40.39) N for groups 1 and 2, respectively, with no statistically significant difference. Majority of samples in Group 1 (74% vs. 65%) had “clean breaks” where the composite fractured without any dentine attached, while the rest of the samples had some dentine attached. Conclusions: ZO-E can be used for temporary fillings without affecting bond strength of subsequent composite restorations.}, keywords = {Composite Resin,Shear bond strength,zinc oxide-eugenol}, url = {https://jdmt.mums.ac.ir/article_14615.html}, eprint = {https://jdmt.mums.ac.ir/article_14615_dda0eac2c08f6caa9b914252cd04b68d.pdf} }
