“…It is generally agreed that glass ionomer materials exhibit higher release of fluoride than composite resin materials due to their composition and structure (Kuşgöz et al 2010;Dionysopoulos et al 2013). Rajtboriraks et al (2004) who investigated the alterations in fluoride levels of biofilms and saliva after the placement of a glass ionomer sealant (Helioseal F) or a resin-based FS (Teethmate F) concluded that Helioseal F which contains fluorosilicate glass presented significant increase in biofilm fluoride level only 24 h after FS placement.…”

“…Resin-based FS are mainly used for sealing because they offer superior mechanical properties, wear resistance and retention rates in comparison with glass ionomer sealants (Mejàre et al 2003;Papacchini et al 2005). Moreover, the incorporation of fluoride in resin-based FS provides fluoride release and recharge abilities to inhibit demineralization of the adjacent tooth structure but lower compared to glass ionomer sealants (Kuşgöz et al 2010). It is well documented that the presence of fluoride ions in low, sustained concentrations, for a sufficient period of time may lead to an anti-cariogenic effect on the dental tissues (Dionysopoulos 2014).…”

“…Regarding fluoride release of dental sealants, it was observed that fluoride release capacity of glass ionomer sealants is higher compared to resin based sealants [15]. In this study, GIC exhibited a significantly higher fluoride-release pattern compared to CR, LR and CO sealants during the study period.…”

Objective: To compare the mechanical properties, fluoride release, colour stability and spreading characteristics of glass ionomer cement (GIC), compomer (CO), chemical (CR) and light-cured resin based (LR) fissure sealants. Material and Methods: Cylinders were prepared to determine mechanical properties by diametral tensile strength tests (stored for 24h in distilled water at 37°C) and fluoride release (24 hours, 3, 7 and 15 days; deionised water). Disk shaped specimens were prepared to determine colour stability (1 week in pigmenting solution; 37°C; CIE L*a*b*; ΔE). A simplified method of a spreading test was proposed to predict viscosity characteristics of the tested materials. Data were analysed using one-way ANOVA followed by T-test (p<0.05). Results: Results showed differences between materials regarding all tested properties. CO was statistically more resistant than the other materials (p<0.05), but no difference was observed between CR and LR. The fluoride release of GICs was significantly higher than the other materials (p<0.05). CO showed lower ΔE than the other materials in the following order: CO

“…A material with pH stabilizing properties neutralizes the acidic pH of the oral environment and maintain it at levels where demineralization will be inhibited 18) . Fluoride-containing resin sealants release a slight amount of fluoride compared with that of a conventional sealant 19) . There are two main methods to incorporate fluoride into a pit and fissure sealant.…”

Synthesized mesoporous silica and calcium aluminate cement fillers increased the fluoride recharge and lactic acid neutralizing ability of a resin-based pit and fissure sealant

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 (GICA). Sealant without filler served as control. The samples were immersed in deionized water or a lactic acid solution and the concentration of fluoride in the water, before and after fluoride recharge, and the lactic acid pH change, respectively, were determined. The CAC+SI group demonstrated the highest fluoride release after being recharged with fluoride gel. The CAC+SI group also demonstrated increased lactic acid pH. These findings suggest that a resin-based sealant containing synthesized mesoporous silica and calcium aluminate cement may enhance remineralization due to fluoride release and higher pH.
