Abstract
This study aimed to synthesize fluoridated hydroxyapatite (FA) crystals within preformed metal crowns (PMCs) and assess their anti-cariogenic properties in vitro. FA crystals were grown on etched PMCs and stainless steel discs, which were then, characterized using scanning electron microscopy (SEM). Fluoride release from the FA-coated discs was evaluated, with four groups of discs (n = 6/group) exposed to solutions ranging from pH 4 to 7. The fluoride levels in the solution were measured after each exposure. Additionally, 12 FA-coated PMCs were cemented onto each of six teeth in four groups: FAcoated with glass ionomer (GI) or unfilled resin, non-coated with GI, and non-coated with resin. These teeth were subjected to acidified gelatin (pH = 4.3) exposure for 9 weeks. SEM analysis revealed FA crystal growth on both the interior and exterior of the crowns. An average fluoride release of 0.16 mg/L/cm2 from FA-coated discs at pH 5.0 was recorded. Upon sectioning, FA-coated crown groups exhibited significantly smaller lesions compared to non-coated crown groups
