Effect of SnF2 Mouthrinse on Initial Bacterial Colonization of Tooth Enamel

Abstract
Microbiologic and electron microscopic techniques were used to observe the effects of SnF2 mouthrinse (100 ppm F-) on early plaque formation in vivo. The results of microbiologic determinations indicated that the total number of bacteria and the number of streptococci were greatly decreased in two-day-old plaque samples. Electron microscopy confirmed the marked reduction of bacterial accumulation.
