AIM To compare and evaluate marginal microleakage of CENTION-N with bulk FILL SDR and ZIRCONOMER using confocal microscopy. METHODOLOGY Thirty freshly extracted human maxillary premolars were selected for the study. Standardized mesio-occlusal [MO] cavities were prepared. The specimens were randomly divided into three groups. Group I restored with Cention-N. Group II restored with bulk-fill SDR. Group III restored with Zirconomer. The specimens were thermocycled, and a layer of nail varnish was applied on all surfaces except for 1mm around the restoration margins. The samples were then immersed in 0.6 % rhodamine dye solution for 24 hours. Samples were sectioned and observed under confocal microscope (x10). STATISTICAL ANALYSIS the statistical analysis of this study was done using kruskal wallis and mann whitney U tests. RESULTS A statistically significant difference was observed among all the groups tested. The minimum leakage was seen in group-I (Cention-N) and the maximum in group-III (Zirconomer). CONCLUSION Based on the results of this study, it can be concluded that bulkfill SDR showed least microleakage scores followed by cention-N and zirconomer
