Abstract

Background: Glass Ionomer Cement is a material used in dentistry for coating, as a base, or for complete restoration, depending on its composition. GIC exhibits anti-cariogenic properties due to its fluoride release, which helps protect teeth from decay. It also has a thermal coefficient similar to that of teeth and is highly biocompatible. However, GIC has drawbacks regarding mechanical properties, as it is brittle, prone to wear, and susceptible to abrasion. Purpose: Determine the impact of adding coconut husk fiber nanocellulose (Cocos nucifera L.) on the diametral tensile strength of GIC. Methods: This study used a true experimental laboratory research design with a post-test-only control group design. Four groups were tested, including three treatment groups and one control group. The treatment groups were the GIC group with the addition of 1%, 1.5%, and 2% nanocellulose, and the control group was the GIC group without the addition of coconut husk fiber nanocellulose (Cocos nucifera L.). Each group had seven cylindrical samples with a diameter of 4 mm and a height of 6 mm. Results: The highest mean diametral tensile strength value in GIC was achieved with the addition of 1.5% nanocellulose, resulting in a mean tensile strength value of 11.37 MPa. Conclusion: The results of the one-way ANOVA test indicate a significance value p = 0.002, p < 0.05, suggesting that the addition of coconut husk fiber nanocellulose (Cocos nucifera L.) has an effect on the diametral tensile strength of GIC. The LSD Post Hoc test analysis indicated statistically significant differences in diametral tensile strength among the experimental groups with 1%, 1.5%, and 2% nanocellulose concentrations, p < 0.05.
