The purpose of this study was to evaluate fluoride ion release from a resin-modified glass ionomer cement (Fuji IILC improved, FLC) and a fluoridated resin cement (Panavia F, PF) following different curing methods and storage conditions. The specimens, which were either light-cured (LC) or chemical-cured (CC), were stored in either distilled water (DW) or demineralizing solution (DS; pH 4.5) fo...

FLUORIDE RELEASE AND UPTAKE INTO HYDROXYAPATITE FROM EXPERIMENTAL DENTAL VARNISH. I Ahmed (D.D.S., SODM), S Coleman, and CM Carey, School of Dental Medicine, University of Colorado, Denver, CO. Fluoride releasing dental varnishes (F-varnish) typically contain 5% sodium fluoride (NaF) within a resin or rosin base. The concentration NaF that yields optimal fluoride enamel uptake, release, and ant...

Fluoride release from six light-activated restorative materials, including two resinmodified glass-ionomers, two composites, and two compomers, was evaluated and compared with one conventional acid-based glass-ionomer cement. The amount and rate of release varied among the tested materials. Both resin-modified glass-ionomers and the conventional acid-base glass-ionomer cements released more flu...

This study evaluated the effect of different types of filler in a resin-based pit and fissure sealant on fluoride release, recharge, and lactic acid neutralization. Resin-based sealant was incorporated with 5% w/w of the following fillers: calcium aluminate cement (CAC), synthesized mesoporous silica (SI), a CAC and SI mixture (CAC+SI), glass-ionomer powder (GIC), and acetic acid-treated GIC (G...

PURPOSE The purpose of this study was to formulate and characterize experimental antibacterial fluoride-releasing sealants and compare them with commercial sealants for fluoride release, recharge, adhesion, and microleakage. METHODS Two experimental sealants (Exp-1, Exp-2) containing a synthesized antibacterial fluoride-releasing monomer and fluoride-releasing filler were formulated. Exp-2 al...

The objective of this study was to evaluate fluoride release amounts and patterns from high strength tooth filling material (EQUIATM) which is a conventional Glass Ionomer Cement, and investigate whether the application of nano-filled resin-based coating with different thicknesses has any effect on fluoride release from this new material. A total of 120 disc shaped specimens (10 x 2 mm) of EQUI...

PURPOSE This study was performed to study the pattern of fluoride release from glass ionomer cement, a resin modified glass ionomer cement, a compomer and a composite resin when stored in different storage media. METHODS A total of 60 samples (Tablets of diameter 8.6 ± 0.1 mm and thickness 1.65 ± 0.1 mm) were prepared (15 samples for each material) pertaining to 4 different materials used. Fi...

OBJECTIVES The purpose of this study was to assess the effect of single and combined applications of fluoride on the amount of fluoride release, and the remineralization and physical properties of enamel. MATERIALS AND METHODS Each of four fluoride varnish and gel products (Fluor Protector, FP, Ivoclar Vivadent; Tooth Mousse Plus, TM, GC; 60 Second Gel, A, Germiphene; CavityShield, CS, 3M ESP...
