Aim and objective: This study aimed to compare microleakage of resin-modified glass ionomer cement (RMGIC) and alkasite with and without adhesive system in class V cavity. Materials and methods: Thirty class V cavities were prepared on the buccal surface. All prepared samples were randomly divided into three groups. Group I was restored with RMGIC, group II was restored with Cention N after the application of adhesive system, and group III was restored with alkasite. Samples were subjected to 200 thermocycles between temperature baths at 5°C and 55°C. Samples were stained with 2% methylene blue. The teeth were sectioned longitudinally, and the sections were then observed under stereomicroscope at a magnification of 20×. Results: Statistical analysis showed that there was less microleakage in Cention N using adhesive system in both occlusal margin and gingival margin. Conclusion: There were significant differences between RMGIC, alkasite with adhesive system, and alkasite without adhesive system in class V cavity. Least microleakage at the occlusal margin and gingival margin was seen with Cention N using adhesive system and highest microleakage at the RMGIC. Clinical significance: Cention N using the adhesive system affects the microleakage in the class V restoration. The study theorizes that the material restorations showed less microleakage in the occlusal margin than in the gingival margin.
