Comparative Evaluation of Microleakage in Class II Cavity in Primary Molars Restored With Glass Ionomer Cement, Zirconomer, and Cention N Using Stereomicroscope: An In Vitro Study

Background: Microleakage is defined as the passage of bacteria, fluid, molecules or ions between cavity walls and restorative material. There are limited studies in literature that have compared microleakage newer materials. Therefore, aim this study to compare evaluate Class II primary molars restored with glass ionomer cement, zirconomer cention N using stereomicroscope. Method: Standardized cavities were prepared on extracted All samples divided into 3 experimental groups follows: Group I- GIC (GC Universal Restorative); II- Zirconomer (SHOFU Inc., Kyoto, Japan) III- Cention-N (Ivoclar Vivadent). The teeth thermocycled, immersed methylene blue dye sectioned along mesiodistal direction. penetration at occlusal surface cervical was evaluated a stereo-microscope. Data analysed Krushal-Wallis test (Non-parametric ANOVA). Results: Among three materials, Cention showed least both surface. Conclusion: material displayed lesser Zirconomer.
