Article Abstract
The aim of this study was to compare the potential of standard ion-releasing materials to repair demineralized lesions with recently introduced alkasite and glass hybrid materials. Glass ionomer (GC Fuji TRIAGE), two glass hybrids (EQUIA Forte HT, Riva SC), calcium silicate cement (Biodentine) and an alkasite (Cention Forte) were tested. A total of 72 human third molars were used for sample preparation; on the dentine surface, a class-I cavity was prepared, and one half was covered with nail varnish. The teeth were subjected to a demineralization protocol, filled with the examined materials, and cut in half. The evaluation included a dentine microhardness assessment ( = 10) and SEM/EDS analysis ( = 2). The results were analyzed using SPSS 22.0 statistical software and compared using an analysis of variance and Scheffe post-hoc test. The statistical significance level was set to 0.05. Mean microhardness values (HV0.1) after 14 and 28 days were, respectively: EQUIA Forte HT (26.7 ± 1.45 and 37.74 ± 1.56), Riva Self Cure (19.66 ± 1.02 and 29.58 ± 1.18), Cention Forte (19.01 ± 1.24 and 27.93 ± 1.33), Biodentine (23.35 ± 1.23 and 29.92 ± 1.02), GC Fuji TRIAGE (25.94 ± 1.35 and 33.87 ± 5.57) and control group (15.57 ± 0.68 and 15.64 ± 0.82). The results were significantly different between most groups ( < 0.001). SEM/EDS revealed varying patterns, material deposits and distinct elemental variations. To conclude, all materials increased microhardness and affected the dentine surface appearance and chemical composition; EQUIA Forte HT demonstrated the most pronounced effects.

Article Synopsis
- In 2017, Europe banned the use of amalgam fillings for children under 15 and pregnant/breastfeeding women, creating a demand for better alternative materials.
- This study tested the surface roughness of five different amalgam-replacement materials using six finishing techniques across three time points, involving 960 samples made from 3D-printed molds.
- Results showed that conventional and hybrid glass-ionomer cements had smoother surfaces than high-viscosity alternatives, with some materials demonstrating stable roughness over time, emphasizing the need for careful selection of finishing methods.

Background: This study aimed to determine the fluoride release and flexural strength of four ion-releasing restorative materials.
Material And Methods: A total of 80 samples of four different materials were prepared in standardized molds: Ketac Universal, Beautifil II, Cention N, and Equia Forte Fil. The fluoride release was quantified at 1, 3, 7, 14, and 28 days post-immersion using an ion-selective electrode.

Article Synopsis
- Dental restorative materials can lead to bacterial growth, so it's important to find materials that reduce microbial adherence for better dental health and longer-lasting restorations.
- The study compared the bacterial adhesion on three different dental materials: a nanohybrid resin composite, a glass hybrid restorative, and an alkasite, while also examining their surface roughness.
- Results showed that the alkasite had the lowest bacterial adhesion, while the nanohybrid composite had the smoothest surface, but no direct link was found between adhesion and surface roughness across the materials.
