“…The use of fluoride-releasing restorative materials has gradually increased because of the inhibitory effects of fluoride on caries 5,11,13 while several laboratory studies have been also performed to evaluate the amount of fluoride release from the materials. 13,14,15,16,27 It has been reported that the higher fluoride release of GICs could provide higher antibacterial activity. 15,17 The fluoride release of restorative materials differs based on various factors such as material type, chemical composition, powder-liquid ratio used during material preparation, mixing method, surface area of material exposed to the environment, storage medium, pH of the environment or storage medium, surface treatment, and finishing procedures.…”

“…This result is also in agreement with the findings of previous studies. 13,16,28 It has been reported that the fluoride release capability of Beautifil II was lower than that of glass-ionomer based materials. 16,28 Beautifil II is a giomer material where S-PRG filler particles are incorporated in the resin matrix.…”

“…As a result, high viscosity GIC, ceramic reinforced GIC, zirconia reinforced GIC, and calcium fluorapatite nanocrystals-reinforced GIC (Glass carbomer) have been developed. 15,16,17 One of the recent developments in the fluoride-releasing restorative materials has been the introduction of the giomer materials. Giomer is a hybridized material of GIC and composite resin, containing surface pre-reacted glass ionomer (S-PRG) filler particles within a resin matrix.…”

The purpose of this study was to evaluate the effect of ionizing radiation from high energy X-ray on fluoride release, surface roughness, flexural strength, and surface chemical composition of the materials. The study groups comprised five different restorative materials: Beautifil II, GCP Glass Fill, Amalgomer CR, Zirconomer, and Fuji IX GP. Twenty disk-shaped specimens (8x2 mm) for fluoride release and 20 bar-shaped specimens (25 x 2x 2 mm) for flexural strength were prepared from each material. Each material group was divided into two subgroups: irradiated (IR) and non-irradiated (Non-IR). The specimens from IR groups were irradiated with 1.8 Gy/day for 39 days (total IR = 70.2 Gy). The amount of fluoride released into deionized water was measured using a fluoride ion-selective electrode and ion analyzer after 24 hours and on days 2, 3, 7, 15, 21, 28, 35, and 39 (n = 10). The flexural strength was evaluated using the three-point bending test (n = 10). After the period of measurement of fluoride release, seven specimens (n = 7) from each group were randomly selected to evaluate surface roughness using AFM and one specimen was randomly selected for the SEM and EDS analyses. Data were analyzed with two-way ANOVA and Tukey tests (p = 0.05). The irradiation significantly increased fluoride release and surface roughness for Amalgomer CR and Zirconomer groups (p < 0.05). No significant change in flexural strength of the materials was observed after irradiation (p > 0.05). The ionizing radiation altered the amount of fluoride release and surface roughness of only Amalgomer CR and Zirconomer. The effect could be related to the chemical compositions of materials.

“…28 The GIC can be a satisfactory alternative therapy in these cases with a superior outcome compared with composites, especially with the release of fluoride, which is an important factor in the prevention against secondary caries. 29 "EQUIA" is considered as less techniquesensitive than resin composite; it is moisture-tolerant and allows a bulk filling technique since it does not undergo volumetric shrinkage during polymerization, unlike composites. 30 Thus, it provides a significant gain of clinical time.…”

Reinforced glass ionomer cements have been widely used in pediatric dentistry to prevent dental caries. However, the influence of biomaterial light-curing and its anticariogenic effects remain unclear. This study evaluates the influence of the lightcuring time on fluoride release, surface topography, and bacterial adhesion in two types of resin-modified glass ionomer cements (RMGICs). One hundred disks were made, and samples were divided into two groups (n = 50 per group), according to each dental material (Vitremer™ and Ketac™ N100), and also divided into different light-cured times (10, 20, 30, 40, and 60 s). They were placed in phosphate-buffered saline solution (PBS) to measure the fluoride release. Subsequently, an independent sample of RMGICs per group was examined using atomic force microscopy (AFM).Four disks per group were incubated in a brain heart infusion (BHI) medium that was inoculated with Streptococcus mutans GS5 to evaluate the bacterial adhesion by 3-4,[5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide cell viability assay (MTT assay). The fluoride release was related to the light-curing time and gradually decreased as the light-curing time increased in both materials. Surface topography in Vitremer™ presents more irregular surfaces than Ketac™ N100. For S. mutans adhesion, the smallest number of cells per milliliter (cell/ml) was found at 40 s for Vitremer™ and at 30 s for Ketac™ N100. Thus, the shorter light-curing times allowed for major fluoride release in both materials. However, the RMGICs showed different patterns of bacterial adhesion according to the brand and light-curing time. K E Y W O R D S bacterial adhesion, fluoride release, light-curing time, resin-modified glass ionomer cements, surface topography 1 | INTRODUCTION Currently, glass ionomer cement (GIC) is considered to be a biomaterial that may inhibit caries due to their release fluoride and Gabriela Olmos-Olmos and Bernardo Teutle-Coyotecatl contributed equally to this work.
