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: E glass fiber dental is a fiber that is often used in dentistry. The availability of E glass fiber in Indonesia is still very limited. Various types of non-dental glass fiber materials are found in the market as engineering materials with relatively cheap prices so that they are expected to be used as an alternative to E glass fiber dental, which one of is coconut fiber. The composition of non-dental glass fiber is almost the same as that of dental E glass fiber. The composition affects the mechanical properties and chemical properties of the fiber. Glass fiber compositions such as Na2O and K2O will increase water resistance. Method: This study was conducted using a post test only control group design. The material used in this study was a composite of coconut coir fiber. The subjects of the coco fiber composite were divided into 4 groups for solubility test based on ISO 4049. The results obtained were analyzed using one-way ANOVA (p = 0.000). The results showed the lowest mean component solubility (%) was in the coconut fiber composite group A (0.476±0.03) and the highest yield was in the coco coir fiber composite D (0.6±0.01). Results: The results of the one-way ANOVA test showed a significant difference in the coco fiber composite in the solubility of the components (p
