“…However, extremely high microleakage values greater than those observed in our study have also been reported 16) . Few studies have assessed its additional fluoride-releasing property 6) and pH buffering mechanism 7,8) . Though these cariostatic properties were not measured in this study, its use in clinical settings has to be decided based on weighing both its physical and cariostatic properties.…”

“…The application of self-etching adhesives instead of acid etching might simplify the clinical workflow, reduce application times and achieve acceptable cooperation from children. Most recently, a new product (BeautiSealant, Shofu, Kyoto, Japan) featuring reduced working time and fluoride-releasing and pH-buffering properties was released on the dental market [6][7][8] . Stringent testing of new materials is imperative before formulating clinical recommendations.…”

This study aimed to evaluate the shear bond strength (SBS) and microleakage of a new self-etch adhesive-based fissure sealant (EG) on aprismatic enamel in comparison to conventional fissure sealing with 30 s acid etching (CG). The fissures were sealed according to the manufacturer's instructions. Each group was divided into 3 subgroups: 1-day water storage, 3-month water storage, and 5,000× thermocycling. After measuring SBS using the Ultradent method, failure mode was analyzed. In additional 16 teeth, microleakage was tested using dye penetration method. Pairwise comparisons were analyzed using Mann-Whitney U-Test. Multiple linear regression was performed to assess the factors influencing on SBS. EG had significantly lower mean SBS (4.1 MPa±2.1) than the CG (17.6 MPa±6.4). CG (1.1%) performed significantly better than the EG (12.8%) in microleakage analysis. The tested EG yielded significantly inferior results and its clinical use should be decided after weighing its pros and cons.

“…The material was infused into the Teflon mold and pressed between two glass slabs with a transparent matrix in between and allowed to set inside the mold for 7 min through chemical curing[ 3 ] or light cured (Elipar, wavelength 430–480 nm; light intensity 1200 mW/cm 2 , 3M ESPE, St. Paul, MN 55144-1000 USA 1-800-634-2249) through the glass slides for 40 s on both the surfaces. Specimens were taken out of the Teflon mold and light cured for 40 s on the sides[ 2 ] and stored at 37°C in 100% humidity for 24 h and later transferred into polyethylene containers containing 10 ml of deionized water.…”

Aim:The aim of this study was to evaluate and compare the fluoride ion release and uptake of glass ionomer cement GP IX Extra (GE), EQUIA® Forte Fil (EF), Beautifil Bulk (BB), Dyract® XP (DXP), Tetric N-Ceram® (TNC) in vitro.Materials and Methods:The restorative materials were divided into five groups (n = 12), namely G1 – GE, G2 – EF, G3 – BB, G4 – DXP, G5 – TNC. Fluoride release was checked using fluoride ion-selective electrode (Orion 9609BNWP, Ionplus Sure-Flow Fluoride, Thermo Scientific, USA) at time intervals of 1 day and thereafter at 3, 7, 14, 21, and 28 days. Following this, fluoride recharge was done with 1.23% acidulated phosphate fluoride gel (12,300 ppm, Pascal International Inc., 2929 Northup Way, Bellevue, USA) after 28 days and each sample was re-checked for fluoride release at the same time intervals.Statistical Analysis:One-way ANOVA with post hoc Games–Howell test for intergroup and repeated measures ANOVA with post hoc Bonferroni test for intragroup analysis. P < 0.05 was considered statistically significant.Results:On intergroup analysis, Group 2 showed high values of fluoride release and recharge at all-time intervals which were significantly higher (P < 0.001) than Groups 1, 3, 4 and 5. Intragroup analysis showed significantly higher (P < 0.001) fluoride release and recharge at the end of day 1 which decreased progressively with time for all the tested materials.Conclusion:EF showed the highest fluoride release and recharge potential across all time intervals compared to other tested restorative materials and the greatest fluoride release was seen on day 1.

“…It was finally allowed to set [3]. Similar methodology was adopted for RMGIC and Cention N with an additional step of light curing, where the samples were light-cured from the top as well as from the bottom for 20 seconds using LED light-curing unit (Blue phase, Ivoclar Vivadent AG, Schaan, Liechtenstein) emitting blue light with intensity of 1200 Mw/cm² and wavelength of 430-480 nm [5].…”

To compare the fluoride release from Conventional Glass Ionomer Cement (GIC), Resin Modified GIC (RMGIC), and Cention N Alkasite Material. Material and Methods: Forty-five disc-shaped specimens of three different restorative materials (Conventional GIC, RMGIC, and Alkasite material) were made and divided into 3 groups (n=15). Fluoride release was evaluated at the end of Day 1, 7, 14, and Day 28 using fluoride ion-selective electrode. Intergroup and Intra-group analysis was done using One-way ANOVA with a Post-hoc test. A p-value of <0.05 was considered statistically significant. Results: Cention showed more fluoride release (in parts per million) than GIC and RMGIC at increased time duration. However, at the end of day 1, there was lesser fluoride release with Cention, as compared with the other groups. Conclusion: The new Alkasite restorative material showed promising results in terms of fluoride release and is better than GIC and RMGIC at increased time duration.
