The highest micro-leakage value was found with group I with a score of 2.2 ± 1.09 and the least score was recorded for group III (0.8± 0.37) with p value = (0.17) being highly significant this is might be because of Cu-NP having increased surface area that improves the physio-mechanical, hence more prevention in seepage of oral fluids.
