Özet
Objectives: The study aims to evaluate the influence of cavity disinfectants on the shear bond strength between Biodentine and mineral trioxide aggregate (MTA) associated with conven- tional glass ionomer (GIC) or resin-modified glass ionomer (RMGIC). Methods: For the study, 144 acrylic mounts were prepared and divided into four groups: MTA-GIC, MTA-RMGIC, Biodentine-GIC, and Biodentine-RMGIC. These were further divided into cavity disinfectant subgroups: sodium hypochlorite (NaOCl), chlorhexidine, and control. Glass ionomers were applied to the silicate cements after performing cavity disinfection. Shear bond strength was analyzed. For statistical analysis, Student’s t-test and one-way ANOVA were used. Results: RMGIC showed lower shear bond strength values to MTA and Biodentine than CGIC in all subgroups (P < 0.05). The shear bond values were lower in chlorhexidine than in NaO- Cl and control groups (P < 0.05). Biodentine and MTA had statistically similar shear bond values to the glass ionomer cements (P > 0.05). The failure types were 38.88% adhesive, 30.55% mixed, and 30.55% cohesive. Conclusions: GIC bonded more strongly to MTA and Biodentine than RMGIC. MTA and Bio- dentine bonded similarly to glass ionomers. Chlorhexidine decreased bond strength, while NaOCl did not.
