Antibacterial effect of different PS supernatants in solution and gel forms against E. faecalis. A: ZOI of the antibacterial activity of four experimental groups of PS solution. 1: Lactobacillus plantarum, 2: Lactobacillus rhamnosus, 3: Lactobacillus acidophilus, 4 (Mix): Cocktail mix and one control group: distal water. The cocktail mix showed the largest ZOI (16 mm). B: ZOI of the antibacterial activity of four experimental groups of PS gel. 1: Lactobacillus plantarum, 2: Lactobacillus rhamnosus, 3: Lactobacillus acidophilus, 4 (Mix): Cocktail mix and one control group: poloxamer gel. The cocktail mix showed the largest ZOI (15 mm). *The label was set to mark the plate with PS gel after the calibrated observers measured the ZOI
