Abstract

Background: Glass ionomer cement (GIC) is widely recognized as the prevailing direct esthetic restorative material. In order for a restoration material to be considered effective, possess favorable physical and mechanical properties. Incorporating with hydroxyapatite (HA) can provide these properties. This research is to investigate the impact of integrating HA into GIC on the flexural strength and scanning electron microscopy (SEM) of the fractured surfaces. Methods: The study consisted of 28 samples of GIC, which are fabricated in the shape of rectangular prisms (25x2x2mm). The samples were divided into four groups n=7. Group 1 is a control group (GIC), Group 2 GIC+2%HA, group 3 GIC+2%HA, and GIC+4%HA. The flexural strength of the sample was evaluated by a Universal testing machine, followed by an examination of the fracture surface using SEM. Result: The Brown-Forsythe was used as data analysis to examine the flexural strength values across all groups, resulting in a statistically significant p-value of less than 0.05. The addition of HA does not result in a significant increase in the flexural strength value of the glass ionomer cement (GIC). The integration of microstructure based on scanning electron microscopy (SEM) pictures demonstrates improved visual quality following the incorporation of HA. Conclusion: The addition of HA to GIC did not result in a significant change in flexural strength compared to the control group. However, GIC group with 2% HA exhibited the highest average flexural strength value among all the groups

Abstract

Background: Biphasic calcium phosphate (BCP) is graft material contained HA and TCP. Tegilarca granosa shell is a natural source that may converted into BCP. This study aims to determine the composition and cytotoxicity of BCP synthesized from Tegilarca granosa shell used various hydrothermal hours and to evaluate the mechanical properties of BCP scaffold. Methods: Tegilarca granosa shell was converted into BCP using hydrothermal method at 200˚C for 6h (Group 1); 9h (Group 2); and 12h (Group 3). The composition was determined by XRD and the cell viability were evaluated using MTT Assays. Each group was added with 20% gelatin ratio 50:50 (w/v) and freeze-dried to form scaffold. Scaffolds (Ø6mm x 4mm) were prepared for diametral tensile strength (DTS) test (n=6) and scaffolds (Ø7mm x 11mm) were used for compressive strength (CS) test (n=6). All data were analyzed using Kruskall-Wallis followed by Mann-Whitney test. Results: The composition of BCP (HA/ TCP) at Group 1, Group 2, and Group 3 were 81.80%/14,10%; 87%/6%; and 72%/21%. The cell viabilities were good for all groups. The DTS and CS test showed there was a significant difference between Group 1 and Group 3 scaffold, meanwhile there was no significant differences between Group 2 and Group 3 scaffold. Group 3 scaffold showed the highest DTS and CS, 6.921 MPa and 1,233 MPa. Conclusion: The BCP composition were depent on hydrothermal hours. Although all scaffold groups were non-toxic, but BCP scaffold synthesized from Tegilarca granosa shell using hydrothermal for 12 hours showed the highest mechanical properties.
