In the original publication [1], there was a mistake in the legend for Figure 3, subtitle B. The term “increased” should be replaced with “decreased”. The correct legend appears below. The authors state that the scientific conclusions are unaffected.
The correct legend is as follows:
Figure 3.
Effects of R. palmatum root extract on S. oralis and P. gingivalis biofilms. After two hours of incubation, viability of S. oralis and P. gingivalis in 24-h biofilms was significantly inhibited by low concentrations of R. palmatum root extract of at least 1.95 mg/L-with a greater decrease in the viability of P. gingivalis. (A) Treatment with 1.95 mg/L and 31.25 mg/L R. palmatum root extract increased biofilm volume of S. oralis, whereas biofilm volume was decreased by 500 mg/L R. palmatum root extract. (B) Treatment with 1.95 mg/L and 500 mg/L R. palmatum root extract significantly decreased biofilm volume of P. gingivalis. (C) Treatment with 1.95 mg/L or more of R. palmatum root extract significantly decreased viability of S. oralis in biofilms. (D) Treatment with 1.95 mg/L or more of R. palmatum root extract significantly decreased viability of P. gingivalis in biofilms. (E) Treatment with 1.95 mg/L and above of R. palmatum root extract increased metabolic activity of S. oralis in biofilms. (F) Treatment with 1.95 mg/L or more of R. palmatum root extract increased metabolic activity of P. gingivalis in biofilms. N = 6 with S. oralis strain ATCC 9811 and P. gingivalis strain ATCC 33277/DSM 20709. * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001.
