ABSTRACT: Our aim was to assess the modalities of use and the anti-inflammatory activity of enoxolone included in toothpaste and in a mouthwash solution.
We used gingival fragments kept alive during 3 days at 37 degrees C. To induce inflammation, inflammatory mediators (SP and LPS) were applied to culture medium on contact with corium. The toothpaste versus placebo was applied on epithelium, in double blind. Histological analysis was then performed on hematoxylin and eosin stained slides. Edema was evaluated with semi-quantitative scores. Vasodilatation was studied by counting the percentage of dilated vessels according to scores and the surface of these dilated vessels by morphometrical image analysis. An inflammatory cytokine, IL8, was measured in culture supernatants. Dosing IL1alpha tested the mouth solution.
The toothpaste induced a significant decrease of edema, vasodilatation, and IL8 excretion. The enoxolone solution induced a decrease of IL1alpha.
Enoxolone demonstrated an anti-inflammatory property whatever the carrier was.

ABSTRACT: The aim of this study was to evaluate and to compare the potential for wound healing of the buccal mucosa with the use of two mouth rinses; one containing 0.10% chlorhexidine with alcohol, the second containing 0.12% chlorhexidine without alcohol.
Using a model of human buccal mucosa kept alive ex vivo, an immunohistochemical assessment of the mitotic potential of epithelial cells and a biochemical evaluation of the capacity of the fibroblasts of the gingival mucosa to synthesize collagen was performed.
A mouth rinse containing 0.10% chlorhexidine with alcohol (Eludril) did not alter the potential for epithelial proliferation and for collagen synthesis within the gingival chorion grown in survival conditions. The results revealed a significant difference between the two mouth rinses for each of the parameters studied. The most favourable results were obtained with the mouth rinse containing alcohol.
The presence of alcohol in a mouth rinse containing 0.10% chlorhexidine has no deleterious effects on healing capacity. On the contrary, it helps stimulate wound healing. The combination of chlorhexidine plus alcohol is superior for healing, chlorhexidine alone does not show any significant difference compared with the control.

ABSTRACT: Our aim was to evaluate the effect of a gingival gel containing chlorhexidine and Rheum Palmatum extract on gingival fragments stimulated by SP (substance P) and lipopolysaccharides (LPS).
Gingival fragments were maintained in survival for 3 days at 37 degrees C. To induce inflammation, SP and LPS were applied to the culture medium in contact with the corium. The gingival gel was applied on epithelium. Histological analysis was then performed on hematoxylin and eosin stained slides. Edema was evaluated with semi-quantitative scores. Vasodilation was studied by counting the percent of dilated vessels according to scores and the surface of these dilated vessels by morphometrical image analysis. An inflammatory cytokine, IL8, was measured in culture supernatants. Immunohistochemical expression of metalloproteinase type 9 (MMP9) implicated in inflammatory processes, was also studied (% of positive cells).
Edema, vasodilation and IL8 were significantly increased after application of SP and LPS. Application of gingival gel showed a significant decrease of these parameters. A significant decrease of MMP9 on fibroblasts and mononuclear cells was observed after use of gingival gel.
