Objective: This study aimed to assess the in vitro cariogenic potential of some Bifidobacterium species in comparison with caries-associated bacteria. Design: Bifidobacterium lactis, Bifidobacterium longum, Bifidobacterium animalis, Bifidobacterium dentium, Lactobacillus acidophilus, Lactobacillus casei, Actinomyces israelii, Streptococcus sobrinus and Streptococcus mutans were tested for acidogenicity and aciduricity by measuring the pH of the cultures after growth in glucose and bacterial growth after exposure to acid solutions. Biofilm biomass was determined for each species either alone or associated with S. mutans or S. mutans/S. sobrinus. Enamel hardness was analyzed before and after 7-days biofilm formation using bacterial combinations. Results: B. animalis and B. longum were the most acidogenic and aciduric strains, comparable to caries associated bacteria, such as S. mutans and L casei. All species had a significantly increased biofilm when combined either with S. mutans or with S. mutans/S. sobrinus. The greatest enamel surface loss was produced when B. longum or B. animalis were inoculated with S. mutans, similar to L. casei and S. sobrinus. All strains induced similar enamel demineralization when combined with S. mutans/S. sobrinus, except by B. lactis. Conclusion: The ability to produce acidic environments and to enhance biofilm formation leading to increased demineralization may mean that Bifidobacterium species, especially B. animalis and B. longum, are potentially cariogenic.
