Evaluation of the Physical Properties of Different Modifications of Glass Ionomer Dental Restorative Materials in Primary Dentition: A Comparative Ex Vivo Study
Year: 2025
Type: article
Abstract: Objectives: This study aimed to evaluate and compare the physical properties of different modifications of glass ionomer cement, namely giomer, zirconomer, and type IX glass ionomer cement (GIC) (pediatric), with resin-modified glass ionomer cement (RMGIC) in the primary dentition in terms of their compressive strength (CS), flexural strength (FS), wear resistance, and microleakage. Materials and methods: = 14) were prepared and subjected to thermocycling after storage in distilled water for 24 hours. After applying two coats of nail varnish 1 mm short of the restorative margins, samples were sectioned buccolingually and immersed in methylene blue dye for 24 hours. The evaluation of the cut sections was done using a stereomicroscope. The data obtained were subjected to statistical analysis. Results: Type IX GIC (pediatric) exhibited significantly greater CS, FS, and wear resistance in primary teeth as compared to RMGIC, giomer, and zirconomer in primary teeth. However, there was no significant difference in microleakage among the tested restorative materials. Conclusion: and clinical trials with large sample sizes are recommended to validate these results. Clinical relevance: Although GIC is the most frequently used dental material for restorative purposes in pediatric dentistry, the long-term success of conventional GIC is questionable due to suboptimal physical properties. The results of the study will help restore primary teeth with improved physical properties and long-term success. How to cite this article: Study. Int J Clin Pediatr Dent 2025;18(S-1):S86-S93.
