Abstract

Abstract The effect of zinc sulfadiazine (ZnSD) and silver sulfadiazine (AgSD) on reducing plaque formation and gingivitis was studied in 12 beagle dogs over a 14‐week period. 12 beagle dogs were scaled, root planed and pumiced to bring them to a similar level of gingival health, prior to placing them on a diet of Purina Dog Chow softened with canned gravy and molasses to promote the build‐up of plaque and the initiation of gingivitis. At the end of 8 weeks, the dogs were determined to have substantial bacterial plaque accumulation and apparent gingivitis. Thereafter, 4 dogs were treated 2 × daily with topical applications of 3% zinc sulfadiazine; 4 dogs were treated with 2% silver sulfadiazine while 4 dogs were treated with placebo gel serving as control over a 14‐week treatment period. By week 2, the zinc and silver sulfadiazine dogs showed a significant decrease in gingival index which was maintained throughout the study. Additionally, by week 2, the % of sites with bleeding was also seen to decrease significantly in the experimental groups. The plaque index remained consistent in all 3 groups until week 6 when the 2 experimental groups indicated significant decrease in plaque accumulation as compared to controls. Probing depths were also seen to decrease significantly in the experimental groups after 10 weeks of therapy. The mean stain index was similar in all 3 groups of dogs throughout the study. Data indicate that both zinc and silver sulfadiazine inhibit plaque formation and reduce existing gingivitis in beagle dogs.
