Introduction: Achieving a strong and stable bond between resin composite and dentin remains a subject of debate in restorative dentistry. The aim of this study was to evaluate the effects of glutaraldehyde, hesperidin, and epigallocatechin gallate (EGCG) as collagen cross-linking agents on dentin bond strength by enhancing the stability of collagen fibers.
Materials and Methods: In this in vitro experimental study, 48 sound human molars were collected. After preparation to expose the dentin surface, the teeth were etched with 35% phosphoric acid. The specimens were randomly divided into four groups: 1. application of 2% hesperidin, 2. application of 5% glutaraldehyde, 3. application of 0.02% EGCG, and 4. control group (no treatment). After restoration with composite, the microtensile bond strength (μTBS) was evaluated. Data were analyzed using one-way ANOVA and Tukey's post hoc test.
Results: The μTBS in the EGCG-etched samples was higher than in samples etched with the other cross-linking agents; however, no significant difference was found between the groups treated with collagen cross-linkers (glutaraldehyde, hesperidin, and EGCG) and the untreated control group. A significant difference in bond strength was observed between the hesperidin and glutaraldehyde groups (P = 0.023), and between the hesperidin and EGCG groups (P = 0.005), while no significant differences were found between any of the treatment groups and the control group.
Conclusion: The application of collagen cross-linkers did not increase the microtensile bond strength of composite to dentin.
