皆さんこんにちは。

今回もヒポクロの抗菌作用に関する論文について

紹介します。

失活した単根歯60本を用いたin vivoの研究です。

The antibacterial action of sodium hypochlorite and EDTA in 60 cases of endodontic therapy

In this study the antibacterial effect of irrigating infected root canals with 0.5 and 5 per cent sodium hypochlorite solutions was evaluated clinically. The results indicated that there was no difference between the antihacterial effect of these two solutions. The combined use of EDTA and 5 per cent sodium hypochiorite solution was more efficient than the use of sodium hypochiorite solutions alone.

つまり…前回同様、0.5％と5.0％という

10倍の濃度差があるにも関わらず、

ヒポクロの抗菌効果に有意差は無かったということです。
