Hypothesis
Different phosphoric acid products might affect the micro-shear bond strength of composite resin to enamel.
Conclusion
Different phosphoric acid products affect the micro-shear bond strength and enamel surface morphology differently.
Supporting Evidence
- The highest micro-shear bond strength was observed with the Ultradent brand.
- The lowest bond strength was recorded for the SDI brand.
- Significant differences in bond strength were found among the different brands of phosphoric acid.
- SEM images showed varying surface morphologies after etching with different brands.
Takeaway
This study looked at how different brands of acid affect how well a type of glue sticks to teeth. Some brands worked better than others.
Methodology
The study involved 72 extracted human premolar teeth, which were divided into six groups based on the brand of phosphoric acid used for etching before testing bond strength.
Limitations
The study was in vitro, and results may differ in clinical settings due to various factors like temperature and moisture.
Participant Demographics
Extracted sound human first premolar teeth.
