Fluoride release from esthetic restorative materials with and without adhesive.
OBJECTIVE
The purpose of this in vitro study was to compare the effect of surface coating containing fluoride on patterns and amounts of fluoride release from 5 esthetic restorative materials.


METHODS
Twelve cylinders of each material were prepared in a plexiglass mold. The experimental groups (n = 6) were coated with 1 layer of fluoridated adhesive resin, Prompt L-Pop, while the control groups (n = 6) remained uncoated. Fluoride release into deionized water was measured on days 1, 2, 3, 7, 14, 21, and 28 using an ion analyzer. Results were evaluated statistically using repeated measure analysis of variance and Duncan test.


RESULTS
In the uncoated materials, the highest fluoride-releasing material was a resin composite Ariston pHc (140.468 +/- 9.80) followed by Photac-fil (101.200 +/- 5.56), Ketac-fil (91.098 + 4.69), Hytac Aplitip (5.122 +/- 1.00), and Ecusit (0.310 +/- 0.18). Material-coating interaction was found to be significant, but the effect of surface coating was different for each material. Among the coated materials, conventional glass-ionomer cement Ketac-fil released the highest amount of fluoride (93.326 +/- 10.86), followed by Photac-fil (83.666 +/- 4.72), Ariston pHc (53.862 +/- 7.90), Hytac Aplitip (14.634 +/- 2.35), and Ecusit (1.355 +/- 0.29).


CONCLUSIONS
Application of fluoridated adhesive affected fluoride release from each material in varying magnitudes.
