[Root caries incidence with regular use of AmF/SnF2 mouth rinse].

The caries protective effect of an AmF/SnF2 mouth rinse solution on exposed root surfaces was examined in 49 patients who had undergone periodontal surgery. The experimental group (EG, 19 patient) rinsed 1x/d using the F- rinse solution. The control group (KG) consisted of 30 patients. The trial was carried out over a period of 16 months. In addition to a complete periodontal status the root caries index (RCI) was recorded. Although the baseline values were comparable in both groups, there was a lower incidence of root caries in the EG at the end of the clinical trial. This clinical study shows that there is a lower root surface caries incidence after long-term application of the AmF/SnF2 rinse solution.
