Abstract

Background: Glass ionomer cement (GIC) is a dental material often used in clinical practice. However, its use is limited due to its drawbacks. Natural resources such as propolis have been used to mainly enhance GIC’s antibacterial properties, but other properties attributed to this enhancement also require evaluation. Purpose: The study aims to evaluate the surface hardness, the surface roughness, and the water absorption of GIC containing ethanolic extract of propolis (EEP) from Trigona spp. Methods: Samples in this study were divided into four groups: GIC (control group); GIC + 25% EEP; GIC + 30% EEP; and GIC + 35% EEP. Surface roughness was measured using a surface roughness tester. Surface hardness was measured using a micro-Vickers hardness tester. Water absorption was measured by weighing the samples before and after immersion in distilled water. Surface characterization was carried out using a scanning electron microscope (SEM). Data was statistically analyzed using the Shapiro–Wilk normality test and one-way variance analysis along with the post-hoc Tukey’s test to determine significant differences between all four samples. Results: The statistical test showed significant differences in surface hardness and surface roughness between the control group and the GIC + EEP group. However, the test demonstrated no significant differences in water absorption between the control group and the GIC + EEP group. Conclusion: The addition of EEP to conventional GIC can affect its physical properties.

Abstract

Introduction: : Glass Ionomer Cement (GIC) is a dental restorative material that is widely modified to improve mechanical properties, such as compressive strength. Biomaterial that can be used to modify GIC is nanochitosan, a material that has been studied to improve the mechanical properties of GIC. Nanochitosan from Xylotrupes gideon can increase enamel hardness on home bleaching application. Objective: To investigate the effect of nanochitosan from Xylotrupes gideon on compressive strength of GIC. Methods: The research type conducted was an experimental laboratory. Samples of 6 mm (height) × 4 mm (diameter) GIC divided into 10 groups (n=5) that was modified with 10% v/v nanochitosan solution, 5% v/v nanochitosan solution, 10% w/w nanochitosan powder, and with 5% w/w nanochitosan powder. Samples were stored in an incubator at 37°C for 1 hour and 24 hours before testing. Compressive strength was tested using Universal Testing Machine. Result: Nanochitosan modified GIC decreased in compressive strength. The result of Two-Way ANOVA statistical analysis showed that there was no significant difference (p >0.05) between all test groups, while there was a significant difference between the 1 hour and 24 hours test groups (p <0.05). Conclusion: Nanochitosan from Xylotrupes gideon has no significant effect on the compressive strength of GIC.
