Aim: The aim of the present in vitro study was to comparatively evaluate the microleakage in three different esthetic restorative materials in class I cavities using the dye penetration technique. Materials and methods: Class I cavities were prepared on 24 human maxillary premolar teeth. The teeth were randomly divided into four groups of six samples each. Group I: Cention-N without adhesive (Ivoclar Vivadent, India), group II: Cention with adhesive (Ivoclar Vivadent, India), group III: type IX glass ionomer cement (Fuji), group IV: posterior composite (3M ESPE). The specimens were polished, subjected to thermocycling, and suspended in methylene blue dye for 24 hours. The teeth were sectioned longitudinally and the extent of microleakage was evaluated using the stereomicroscope. Results: The results were subjected to statistical analysis using the Pearson's Chi-square test and the interobserver variability was assessed by the Kappa test for interobserver variability. The analysis showed statistically significant results among the groups. Although, Cention N with adhesive showed the least microleakage followed by Cention N without adhesive. Conclusion: All the materials tested were unable to completely eliminate microleakage in class I cavities. However, the newer alkasite material Cention N proved to have the least microleakage among all groups. Clinical significance: According to the present study, Cention N, a newer alkasite restorative material, demonstrated promising results with the least microleakage in comparison with posterior resin composites and glass ionomer cements.
