| Objectives: To test if the alkasite-based composite could encourage the accumulation calcium and phosphorus at tooth/restoration interface and to assess its adhesion to tooth structure using scanning electron microscope (SEM) after pH cycling. Method: Cervical cavities were prepared on the buccal surfaces of 60 molars for the following restoration groups: group 1, Samples were kept moist without any further treatment ; group 2, samples were kept in demineralizing solution; group 3, new alkasite based composite(Cention -N); and group 4, Cention -N with bonding agent ;group 5, A resin-modified glass ionomer restorative material (active bioactive composite);group 6, high-viscosity conventional glass ionomer restorative material(Equia Forte). The restored teeth were PH cycled for 30 days. Each tooth was buccolingually sectioned into two halves. One half was subjected to elemental analysis under low vacuum at 1000× magnification using Energy Dispersive X-Ray (EDX). The recorded values represented the average calcium (Ca) and phosphorus(P) weight percentages. The other half was sputter coated and micromorphological analysis of restoration/Tooth interface was done using SEM (JEOL, JSM 6510 IV, Japan) at 15.0 kV. Micrographs at magnifications of 2000×were captured. Results; after restoration with Cention -N, Active bioactive composite, and Equia Forte the Ca levels were significantly increased. In contrast to restorations with Cention-N with bonding agents Ca levels were insignificantly increased. P levels showed slight insignificant increase after restoration with all tested restorative materials. Conclusion; The tested restorative materials showed promising results regarding remineralization. | ||
