Curcumin as a Promising Antibacterial Agent: Effects on Metabolism and Biofilm Formation in S. mutans

Figure 5

Morphological characteristics of S. mutans biofilm treated with or without drugs. Representative SEM images of 24 h S. mutans biofilm grown in curcumin for 5 min (b) and 24 h (e) and grown in chlorhexidine for 5 min (c) and 24 h (f). The image of 24 h S. mutans biofilm grown in 1% BHIS for 5 min (a) and 24 h (d) as a control. Magnifications of 2000x, 5000x, and 10,000x are shown for each condition. The black arrows highlight the EPS of S. mutans, which was markedly reduced.
