Changes in colony-forming units (Log CFU/mL, means ± standard deviations) of S. mutans after being cultured in the supernatant (Sup.) of S. oligofermentans (So) and L. reuteri (Lr). S. mutans was cultivated in minimal medium (MM), MM with glucose (MM+Glu), MM with glycerol and glucose (MM+Gly+Glu), MM with Lactic acid and glucose (MM+Lac+Glu), MM with arginine and glucose (MM+Arg+Glu) and all-full medium (MM+all) (controls), as well as supernatants of the probiotics. Glucose was additionally added to the MM+Gly, MM+Lac, and MM+Arg group of probiotic supernatants as it is described in section “Culture of S. mutans With Probiotic Supernatants.” Each experiment was repeated three times. Dunnett’s test: *P < 0.05, ***P < 0.001, versus controls.
