A comparative analysis of the amount of fluoride release, recharge, and re-release after uptake in three light-cure orthodontic bonding adhesives – an in-vitro study
Description
Amount of fluoride released (in ppm) by three light-cure orthodontic bonding adhesives (Sheet1). Amount of fluoride(in ppm) released after recharge with 1000ppm of sodium fluoride solution for 5 mins (Sheet 2).

The study compared the fluoride release, recharge, and re-release properties of three light-cure orthodontic bonding adhesives: Group A: Transbond Plus Color Change, Group B: Waldent Orthobond LC, and Group C: Koden EZ Bond. The study conducted an in-vitro investigation using 24 maxillary first premolar teeth bonded with one of three fluoride-releasing adhesives after etching. Each sample was placed in artificial saliva, and the fluoride release was measured over 60 days using a fluoride electrode. After initial release measurement, specimens were soaked in 1000 ppm fluoride solution for 5 minutes, rinsed, and placed in new containers with distilled water before re-release measurements.
