Aim: To evaluate the microleakage of Cention N in comparison with glass ionomer-based Giomer and Vitremer in class II opensandwich cervical lining restorations with Fuji II as a control. Materials and Methods: Cavity preparation and grouping of specimens were performed as follows: the sample size was statistically derived at 50 samples into five groups of n = 10 cavities each. Standardized cavity preparation on the mesial surface at the cementoenamel junction of each tooth was: the width was 5 mm, the occlusal depth was 2 mm, and the axial wall length was 6 mm. The teeth were randomly assigned into five (groups 1–5) groups of n = 10 cavities each; group I and group II are the control groups. The samples were stored in artificial saliva at 37°C for 14 days to ensure resinous hydration of the restorations and then placed in water baths for thermocycling and immersed in methylene blue dye and then sectioned and viewed under a stereomicroscope (20×). The microleakage was scored at the occlusal, cervical, and interfacial surfaces. Results: Statistical analysis for microleakage was done with analysis of variance followed by Tukey’s post hoc test. For the interfacial microleakage, group IV (Cention N as a base) was significantly better than group III (Vitremer as a base) and group V (Giomer as a base) (Table 3, Graph 1). Conclusion: In this in vitro study, microleakage scores of Cention N were better than Giomer and Vitremer and comparable with Fuji II LC, suggesting it could be placed as a cervical lining for class II restoration.
