Résumé
Parodontax dentifrice is a plant-based dentifrice which is supposed to have specific effect in preventing and treating gingivitis. The purpose of the present study was to compare clinical effectiveness of Parodontax and Crest complete toothpaste in controlling gingival inflammation and microbial plaque. This double-blind clinical trial was performed on 40 patients with gingivitis that had been referred to the periodontal department of Shahed Dental School. The subjects were randomly allocated into either the test group [n=20, Parodontax] or the control group [n=20, 7 Crest Complete]. Turesky's Plaque Index and Loe's and Silness's Gingival Index were used to evaluate plaque and gingivitis at baseline and one month after dentifrices' application. Plaque and Gingival index changes were evaluated by Wilcoxon test in each group and Mann-Whitney test between the test and control group. After one month, in the Crest group, PI reduced from 2.58 to 2.46 and in the Parodontax group PI reduced from 2.68 to 2.48. There was a significant reduction in plaque levels in both test and control groups. However, there was no significant difference between the two groups. Gingival index, decreased from 1.43 to 1.22 in the control group and from 1.36 to 1.15 in the test group. A significant reduction in gingivitis was observed in each group, although there was no significant difference between the two groups. Both dentifrices had similar effects on PI and GI. Parodontax dentifrice does not cause significant reduction in gingival inflammation and microbial plaque accumulation
