Effect of Flossing, with and without Iodine, on Human Interproximal Plaque Flora

Abstract
Flossing per se temporarily reduces the proportion of Streptococcus mutans in interproximal plaque when these organisms are present in high numbers. Flossing with iodine reduces the proportion of S. mutans more than flossing alone. However, to maintain low levels, repeated treatment appears to be necessary. Flossing, with or without iodine, does not eliminate S. mutans from interproximal sites and does not significantly alter the proportion of actinomyces.
