Evaluation of the Fluoride Releasing and Recharging Abilities of Various Fissure Sealants.

Purpose: To evaluate the fluoride release from different fissure sealants sold mainly in non-Western countries via a curve-fitting method, and to investigate the ability of these materials to be recharged with fluoride.

Materials And Methods: Four different fissure sealants which the manufacturers claim to release F- were tested; glass-ionomer cement Argecem (AC), the composite resins Fisskhim (FK), Fissulight (FL), Helioseal F (HF). Helioseal (HS), a composite resin not declared to release F, was used as a negative control.
