The aim of this study was to evaluate the effect of chlorhexidine (CHX) application on immediate and two-month bond strength of a filled adhesive system. Methods: Forty eight non-carious human third molars without enamel of occlusal surface were randomly divided into two main groups according to CHX application: control and CHX. Each main group was further subdivided into 2 subgroups depending on storage time: immediate or two-month collagenase storage. In CHX groups, 2 CHX was applied for 30 s. Filled adhesive resin (PQ1) was applied on the etched dentin surfaces and cured in all experimental groups. Composite resin (Amelogen) was placed on the dentin surfaces and shear bond strength (SBS) was evaluated immediately and after two-month storage in collagenase solution. Failure modes were determined by stereomicroscope. Results: There was no significant difference in immediate SBS between groups (P>0.05). After two-month collagenase storage, although SBS was significantly reduced in control group (P<0.05), no significant reduction was observed in CHX group (P>0.05). SBS in CHX group was significantly higher than the control group (P<0.05). Conclusion: The use of CHX had no adverse effect on immediate bond strength of filled adhesive and could preserve the bond strength.
