Effect of Biosilicate Addition on Physical-Mechanical and Biological Properties of Dental Glass Ionomer Cements.

This study investigated the influence of incorporating Biosilicate on the physico-mechanical and biological properties of glass ionomer cement (GIC). This bioactive glass ceramic (23.75% NaO, 23.

Effect of a Self-Assembly Peptide on Surface Roughness and Hardness of Bleached Enamel.

After bleaching, enamel surfaces are damaged, contributing to erosion and tooth sensitivity. Although fluoride is used after bleaching to try and revert alterations, it is not capable of repairing tooth structure. This study compared the effect of a self-assembly peptide (P11-4), with and without fluoride, and sodium fluoride (NaF 2%) on the Knoop microhardness (KHN) and surface roughness (Ra (μm)) of bleached enamel with an in-office bleaching regimen.
