Hypothesis
Do orthodontic adhesives containing fluoride or amorphous calcium phosphate reduce bacterial adhesion and enamel demineralization?
Conclusion
Orthodontic adhesives with fluoride or amorphous calcium phosphate reduce bacterial adhesion and lesion depth compared to a control adhesive.
Supporting Evidence
- Aegis Ortho showed a 20.3% reduction in lesion depth compared to the control group.
- Quick Cure demonstrated a 23.6% reduction in lesion depth compared to the control group.
- Both Aegis Ortho and Quick Cure significantly reduced bacterial adhesion compared to Transbond XT.
Takeaway
This study tested different types of orthodontic glues to see if they could stop cavities from forming around braces. The glues with special ingredients worked better than the regular glue.
Methodology
The study involved 40 human premolars tested with three types of adhesives, and their effectiveness was measured using X-ray photoelectron spectrophotometry and polarized light microscopy.
Potential Biases
Potential bias in sample selection and the artificial nature of the testing environment.
Limitations
The study was conducted in vitro, which may not fully represent real-life conditions in patients.
Participant Demographics
Forty extracted noncarious large human premolars were used.
