evaluation and characterization of some properties of glass ionomer cement reinforced by novel boron nitride nanoplatelets

Purpose: this study characterized and incorporated a novel boron nitride nanoplatelet (bnnp) into conventional cement known as glass ionomer cement (gic) with changed ratios (range from 1%, 3%, 5%, and 7%wt) subsequently.materials and methods: the study examined the impact of adding bnnp on the mechanical characteristics of gic, including its flexural strength (fs), diametral tensile strength (dts), water sorption/solubility, and setting times. the bnnp was characterized using physio-chemical characterization, and brunauer-emmett-teller (bet) testing, and density was also measured. in addition to showing considerably greater dts (16.34± 1.26mpa) and fs (24.037 ± 0.816 mpa), the results showed that 3% wt. bnnp-modified gic specimens decreased in water sorption/solubility 19.358±2.40 and 2.979±0.65 µg/mm3, respectively, compared with traditional gic.results: in this work, a novel bnnp containing gic was created, resulting in a 15% reduction in water sorption. when compared to commercial gic, the demonstrated gic can quadruple the dts and fs.conclusion: for water-based cement types, the glass-ionomer formulations including bnnp exhibit equivalent and acceptable working qualities.
