Effect of amine fluoride (AmF)/stannous fluoride (SnF2) toothpaste and mouthwashes on dental plaque accumulation, gingivitis and root-surface caries

Abstract

The aim of the study was to assess the effect of a toothpaste and mouthwashes containing amine fluoride (AmF) and stannous fluoride (SnF2) on dental plaque, gingivitis and root-surface caries. Forty-four adults participated in a five-month double-blind study. The following combinations of toothpastes and mouthwashes were used: (1) AmF/SnF2 toothpaste and AmF/SnF2 (Meridol) mouthwash (20 patients, mean age 45.7 years), (2) sodium fluoride (NaF) toothpaste and NaF mouthwash (24 patients, mean age 48.8 years). The mean values for dental plaque (Silness-Löe index) were clinically and statistically significantly reduced in both groups, the difference being greater in the AmF/SnF2 group. Sulcus-bleeding index values were clinically and statistically significantly decreased in both groups. There was no marked difference between the groups. The root caries index (RCl, Katz) had decreased by the end of the experiment by 10% in the NaF group and by 47.4% in the AmF/SnF2 group.
