[Analysis of the in vitro antibacterial action of a fluoridated amalgam].
To a conventional silver amalgam alloy was added 1% of stanous fluoride, to prove in vitro, if it presents any antibacteria actions against S. mutans and Lactobacillus acidophilus. Thirteen Petri plate were seeded with S. mutans and 12 Petri plate with Lactobacillus, in both cases, was disposited fluoride containing amalgam and conventional amalgam. The average of inhibition signs in the Petri plates with S. mutans was 1.7 mm in the Petri plates with Lactobacillus the average was 2.4 mm. Is demonstrated that the fluoride containing amalgam has in vitro antibacteria action in comparison with conventional amalgam, that has none.
