Summary
This study found that FluorEver OBA, a fluoride-releasing orthodontic adhesive, releases small amounts of fluoride over time. This could help reduce decalcification around orthodontic brackets after treatment.
Area of Science:
- Orthodontic materials science
- Dental biomaterials
Background:
- Decalcification around orthodontic brackets is a common post-treatment concern.
- Fluoride-releasing adhesives aim to mitigate this issue.
Purpose of the Study:
- To evaluate the in vitro fluoride release of FluorEver OBA, a light-activated, fluoride-releasing composite resin adhesive.
Main Methods:
- In vitro assessment of fluoride ion release from FluorEver OBA over 43 days.
Main Results:
- FluorEver OBA demonstrated fluoride ion release, with a mean of 2.6 ppm on day 1, decreasing to 0.42 ppm by day 2, and 0.04 ppm by day 43.
- The study observed a gradual decline in fluoride ion concentration over the tested period.
Conclusions:
- FluorEver OBA releases clinically relevant concentrations of fluoride ions.
- The findings suggest potential benefits in reducing decalcification during orthodontic treatment.
