Resolution of Gingivitis in Dogs Following Topical Applications of 0.4% Stannous Fluoride and Toothbrushing

Abstract

The efficacy of 0.4% SnF2 rinse in reducing plaque-associated gingivitis around the teeth of 6 adult beagle dogs with existing gingivitis was tested. The Gingival Index (GI) and Plaque Index (PI) were assessed for the mesial, buccal and distal aspects of 4 carnassial teeth and 14 premolar teeth in each dog. The greatest decrease in individual PI scores was observed within 48 h following the brushing and SnF2 rinse regimen. The greatest reduction in GI scores occurred 7-14 days later. Regular SnF2 rinses, in combination with brushing, resulted in a significant reduction of supragingival plaque; brushing alone had only minimal effect. Resolution of gingivitis occurred following the elimination or reduction of plaque. The potential of dilute SnF2 rinses in the treatment of early periodontal disease is of great interest.
