Abstract
Glass ionomer cement (GIC) is a well-known restorative fabric implemented in dentistry. The present work aims to study the effect of hydroxyapatite (HA) addition on physical and structural properties of GIC derived Alumino-Silicate-Fluoride (ASF) glass ceramic sintered at 700 °C. The utilization of waste substances particularly clamshell (CS) and soda lime silica (SLS) glass as substitutes for the respective CaO and SiO2 sources in the fabrication of alumino-silicate-fluoride (ASF) glass ceramics powder. According to the findings of this study, heat treatment had no significant influence on the traditional GIC utilized, but it had a substantial effect on the resin modified GIC, boosting both compressive strength and modulus while decreasing stress relaxation properties and fluoride release. GIC was created using ASF glass ceramics, polyacrylic acid (PAA), and deionized water, with (1-5) wt.% HA powder added to improve the properties of the cement samples. The control and modified GIC samples were created using a 3:1:1 ASF glass ceramics/HA: polyacrylic acid (PAA): deionized water ratio. Before being characterized by density measurement, X-ray diffraction (XRD), Fourier transform infrared (FTIR), and field emission scanning electron microscopy (FESEM), all GIC samples were exposed to five distinct ageing times which are 1, 7, 14, 21, and 28 days. The addition of HA to the GIC formulation results in an increase in density measurement for certain samples. Furthermore, XRD, FTIR, and FESEM analyses showed the existence of the fluorapatite (FA) crystal phase in the GIC sample. XRD study of GIC samples indicated the presence of fluorapatite (FA) crystal peaks, which was corroborated by FTIR investigation, which revealed an asymmetric PO stretching mode at a wavenumber of 1020 cm-1. In addition, FESEM morphology indicates the development of spherical particles and agglomerated needle- like apatite crystals. Overall, the addition of HA to GIC produces good results and improves its properties, therefore encouraging its usage as a restorative material in dentistry.
