Evaluation of the Effect of Nanographene Oxide on Microleakage of Conventional and Resin-Modified Glass Ionomer

Table 4

Occlusal and gingival microleakage of CGIC groups compared to their corresponding groups in RMGIC.

Groups	P-value
	Occlusal	Gingival
CGIC (control) - RMGIC (control)	0.671	0.007
CGIC + 1% nGO - RMGIC + 1% nGO	0.089	0.012
CGIC + 2% nGO - RMGIC + 2% nGO	0.435	0.165

Mann–Whitney U test. CGIC, conventional glass ionomer cement; RMGIC, resin-modified glass ionomer cement; nGO, nanographene oxide.
