Author Information

Primary Institution: Gazi University
Hypothesis
The final irrigation solutions would not impact the bond strength of MTA to the bulk-fill composite.
Conclusion
EDTA significantly reduces bond strength, while chitosan with CHX enhances it.
Supporting Evidence
- EDTA exhibited the lowest shear bond strength.
- Chitosan-CHX showed the highest shear bond strength.
- SEM analysis revealed structural changes in MTA after exposure to different solutions.
- Cohesive fractures within MTA were predominant.
Takeaway
This study looked at how different liquids used in dental procedures affect the strength of a special material used to fix teeth. It found that one liquid weakens the bond, while another makes it stronger.
Methodology
Sixty MTA samples were divided into six groups based on the final irrigation solution, and shear bond strength was measured after exposure to the solutions.
Limitations
The study may not fully simulate clinical scenarios, and the effects of body fluids on MTA's setting time were not considered.
