Aim: The purpose of this study was to evaluate the influence of chlorhexidine (CHX), grape seed extract (GSE), riboflavin/chitosan modification on microtensile bond strength (μTBS) of composite resin to dentin after polymerase chain reaction (PCR) thermocycling.
Materials and Methods: Forty extracted human molars were used and a flat surface was then prepared by removing the occlusal one-third. The teeth were randomly assigned into four groups - Group I in which self-etch adhesive (Adper Easy One) was applied and Groups II, III, IV were pretreated with 2% CHX, 6.5% GSE, and 1% riboflavin/chitosan, respectively, before the application of self-etch adhesive. Composite build-ups were constructed, and PCR thermocycling (5000 cycles) was performed. The μTBS was evaluated using the universal testing machine. Data were analyzed using one-way analysis of variance and Tukey's test.
Results: The mean μTBS values for Group I (control), Group II (CHX), Group III (GSE), and Group IV (riboflavin/chitosan modification) were 30.81, 43.15, 38.79, and 35.07 MPa, respectively.
Conclusion: Pretreatment with CHX and GSE leads to a significant increase in μTBS of composite resin to dentin. |
