This study aims to develop a gutta-percha with antibacterial property. We added an organic antibacterial agent, cetylpyridinium chloride (CPC) into gotta-percha (TACTENDO GUTTA, TG), then investigated antibacterial effect on an oral bacterium, Porphyromonas gingivalis by monitoring optical density of the bacterial culture to examine bacterial growth and viable cell count to examine bacterial activity. TG alone (without CPC) rather inhibited the bacterial growth, but bacterial activity was not clearly observed. However, addition of 0.05% CPC conferred not only inhibition of the growth but also a high bacterial activity. This result suggests that addition of CPC is useful for root canal treatment.
