PERBANDINGAN PELEPASAN ION FLUOR PADA GLASS IONOMER CEMENT DAN RESIN KOMPOSIT FLOWABLE BERFLUOR
Background: Fluoride is a material commonly found in green vegetables, legumes, fish, potatoes, and in products to which fluoride was added such as toothpaste, mouthwash, and fluoride-containing restorative materials. The incorporation of fluoride into restorative materials such as glass ionomer cement (GIC) and fluoride-containing flowable composite resin was intended to allow those materials to release fluoride continuously. This fluoride release functioned to prevent plaque formation and inhibit secondary caries by assisting in tooth remineralization. Aims: To compare fluoride ion release from GIC and fluoride-containing flowable composite resin. Methods: A comparative in vitro laboratory study with a repeated-measures (within-subject) and between-subject design was conducted. Five circular specimens of GIC and fluoride-containing flowable composite resin, prepared according to ISO #7489, were suspended in 20 mL of distilled water. Fluoride release was measured on day-1, day-7, day-15, day-21, and day-28 using a colorimeter. Data were analyzed using independent t-tests and One-way ANOVA with Bonferroni post hoc correction. Results: GIC released significantly more fluoride ions than the fluoride-containing flowable composite resin on day-1, day-7, and day-15, while no differences in fluoride release were observed on day-21 and day-28. Both GIC and the fluoride-containing flowable composite resin exhibited the same release pattern, characterized by a surge on day-1 followed by a sharp decline. Conclusion: GIC released more fluoride ions than the fluoride-containing flowable composite resin. The fluoride-containing flowable composite resin demonstrated a fluoride release pattern similar to that of GIC.
