Comparison of mean (SD) values of fibroblast survival rate of freshly mixed and set form of the same sealer with control group on days 1, 3 and 7 (a) AH plus (p<0.05 for freshly mixed sealer at day 1, 3, and 7) (P>0.05 for set sealer at day 1 and 3 and P<0.05 for day 7), (b) GuttaFlow 2 (P<0.05 for freshly mixed and set sealer at day 1, 3, and 7) , (c) Dia-Proseal (P<0.05 for freshly mixed sealer at day 1, 3, and 7) (P<0.05 for set sealer at day 1 and 7 and P>0.05 for day 3), and (d) Pulpdent Root Canal Sealer (P<0.05 for freshly mixed and set sealer at day 1, 3 and 7). The error bars denote standard deviation (SD)
