Abstract

Glass ionomer cement is a dental restorative material that is widely used in dental application and usually utilized as a filling and luting material. The conventional GIC is also known for its drawbacks where it is lack in terms of physical, bonding and mechanical properties which limits the usage of GIC in dentistry field as a restorative material. The present work focusses on enhancing the properties of GIC by adding hydroxyapatite (HA) to the GIC. In this research alumino-silicate-fluoride (ASF) glass, polymeric acid (PAA) and deionized water were used to prepare the GIC samples. In order to formulate modified GIC samples, the materials were prepared based on 3:1:1 ratio referring to ASF glass/HA:PAA:H2O before undergoes ageing process for five different periods of time. All GIC samples were characterized by density measurement, Fourier transform infrared (FTIR), X-ray diffraction (XRD), Field emission scanning electron microscopy (FESEM). For certain samples, the inclusion of HA to the GIC samples results in an increase in density measurement. The highest density recorded for the GIC samples was 1.82 g/cm3 added with 3% of HA at 28 days of ageing time while the lowest iii density was 1.239 g/cm3 added with 1% of HA. In addition, XRD, FTIR, and FESEM studies further confirmed the presence of the fluorapatite (FA) crystal phase in the GIC sample. The existence of fluorapatite (FA) crystal peaks was found by XRD analysis of GIC samples, which was confirmed by FTIR research revealed an asymmetric PO stretching mode at a wavenumber of 1020 cm-1. Next, FESEM study of the microstructure reveals the production of spherical particles and agglomerated needle-like structures indicating the formation of apatite crystals. Overall, the addition of HA to GIC improves the physical and structural properties of the material for dental applications.
