Figure 1From: Antimicrobial residual effects of irrigation regimens with maleic acid in infected root canals Kaplan-Meier survival probabilities at 60 days (probability of no growth) for experimental groups. Cum survival: percentage of samples that did not show E. faecalis growth at a given time. For clarity: ++, 7% MA + 0.2% CTR. At day 30, there was growth of E. faecalis in 7 out of 12 samples, meaning that 41.67% survived without growing.Back to article page
