Evaluation of Antimicrobial Activity and Cytotoxicity of an Epoxy Resin-Based Endodontic Sealer Containing Nanoparticles Amorphous Calcium Phosphate

Table 5

To assess the significance of variations in the mean cell viability values, an independent samples t-test was performed between the AH Plus + NACP sealer group and the negative control group at different time intervals.

Time (hr)	Mean viability (%) ± SD		P value (t-test)	Significance
	Negative control	AH Plus + NACP
24	95.563 ± 1.50	94.251 ± 0.582	0.4386	NS
72	93.17 ± 1.0	92.129 ± 1.75	0.6182	NS
168	85.339 ± 0.58	83.564 ± 0.64	0.2080	NS

NS, non-significant.
