Figure 1: UltraSeal XT® disk diffusion test. Petri plates containing Brain hearth infusion broth added with Lactobacillus reuteri (a1), Streptococcus mutans (b1) and Streptococcus salivarius (c1) and disks of UltraSeal XT® (50 μl) are shown on the left. On the right (a2, b2, c2), Ultraseal sealant disks were removed from plates, showing underlying halos of growth inhibition by contact
