Zur antimikrobiellen Wirkung von NaF-haltigen Zahnpasten

Einer synergistischen antimikrobiellen Wirkung von 106 NaF-Zahnpasten auf Mikroorganismen des supra- und subgingivalen Biofilms wurde mit dem Agar-Hemmhof-Test nachgegangen. NaF-Zahnpasten mit Zink/Zinn lösten im Mittel Hemmhofzonen gleich Zahnpasten mit NaF allein oder mit natürlichen Wirkstoffen oder Zink aus. Die Wirkung der NaF-Zahnpasten mit Triclosan war am stärksten ausgeprägt. Ob die remineralisierende Wirkung der Zahnpasten in vivo von einer antimikrobiellen Wirkung begleitet ist, bleibt offen.

The antimicrobial efficacy of ingredients in toothpastes with NaF on the synergistic reduction of supra- and subgingival biofilms was determined in vitro. The agar diffusion assay was performed with reference strains. Toothpastes with zinc/tin produced no significantly larger inhibition zones compared with those with NaF or natural antimicrobials or zinc. Triclosan-toothpastes caused the largest inhibition zones. The in vivo implication of the results is still not clear.
