Improvement Effects of Dentifrice Containing Plant Extracts on Periodontal Disease / 日本補完代替医療学会誌

ABSTRACT

Effects of three plant extracts (Hordeum vulgare L., Apocynum Venetum L., Brasenia schreberi J.F.G mel.) on human gingival fibroblasts were examined. As a result, we observed the promoting effect of the extract of Hordeum vulgare L. and the extract of Apocynum Venetum L. respectively on FGF2 and FGF7 production. Moreover, the mixture of the three plant extracts showed the effect of improving the changes in type I collagen gene expression and matrix metalloproteinase 1 gene expression by LPS addition. Next, a dentifrice containing the three plant extracts was subjected to human efficacy trials. We measured periodontal pocket depth, attachment level, bleeding on probing and saliva TNFα as an indicator of periodontal disease. The results suggest that the dentifrice formulated with the three plant extracts were effective for the improvement of periodontal disease.
