Abstract

Aim:  Invitro evaluation of microleakage in Class V Cavities restored with Chemically cured GIC, Light cured GIC, Nanofilled Resin Modified GIC and Cention N using Stereomicroscopic analysis. Materials and Methods: One-Hundred extracted human permanent mandibular 1st and 2nd molar teeth were collected. Class V cavity preparations were done in all the teeth. All the specimens were then divided into 5 groups, with 20 teeth per each group. In Group A: Chemically cured GIC, Group B: Light cured GIC, Group C: Nanofilled Resin Modified GIC, Group D: Cention N, were used as restorative materials. Group E: Control Group in which the prepared cavities were not restored. Dye penetration test was done using Methylene blue dye and the microleakage was measured using Stereomicroscope. Statistical analysis was done by One-Way ANOVA and Post Hoc-Tukey test and the P-value was < 0.0001 and is highly significant. Results: Nanofilled Resin Modified GIC and Cention N showed optimum tooth-restoration interface with minimal or no microleakage compared to Chemically cured GIC, Light Cured GIC and Control Group. Control Group showed maximum microleakage at tooth-restoration interface. Conclusion: Nanofilled Resin Modified GIC and Cention N showed better marginal adaptation with least microleakage compared to Light cured GIC and Chemically cured GIC.
