Objective: To evaluate the antibacterial action of Amalgomer CR and Fuji VII against bacteria causing S-early childhood caries. Materials and Methods: Antibacterial activity of Amalgomer CR and Fuji VII was assessed using the agar diffusion test in triplicate. The powder and liquid of each test material was mixed and inserted in the punched wells (6 mm × 2 mm). A composition of 0.2% chlorhexidine digluconate acted as control. The agar plates were incubated at 37°C for 24 h for Streptococcus mutans, S. salivarius, S. parasanguinis and Actinomyces viscosus, whereas Lactobacillus casei was incubated for 48 h. Sizes of the inhibition zones were calculated by subtracting the diameter of the specimen (6 mm) from the average of the three measurements of the halo. For each test material against each bacteria, 9 measurements were made (3 measurements × 3 times). Kruskal-Wallis test was done to compare the zones of inhibition of test materials against individual bacteria. Pair-wise comparison was done by Mann-Whitney U-test. Results: Amalgomer CR had the most antibacterial against S. mutans (31.0 mm), followed by A. viscosus (21.87 mm), S. salivarius (13.87 mm), S. parasanguinis (10.80 mm), and L. casei (9.69 mm). Fuji VII had the most antibacterial action against S. salivarius (10.65 mm), followed by A. viscosus (9.10 mm). However, it did not inhibit the growth of S. mutans (0 mm), S. parasanguinis (0 mm), and L. casei (0 mm). Conclusion: Amalgomer CR and Fuji VII showed wide variation in antibacterial action against all test organisms.
