Effect of curcumin on live/dead bacteria and thickness of the biofilm of S. mutans. After mature biofilm formed by clinical strains, the biofilm was treated with 500 μM curcumin for 5 min (a) and 24 h (b). The green color of image was for live bacteria, red color was for dead bacteria, merged image was for dead and live bacteria, and three-dimensional reconstruction image was also showed. c and d showed the live bacteria and total bacteria counts after the treatment of curcumin. e showed the change of the biofilm thickness after the curcumin- treated in the SECC and the CF group. The data are expressed as mean ± standard deviation. * indicates that the data for the different groups are statistically different (* P < 0.05, ** P < 0.01, ***P < 0.001)
