| Research Abstract |
First of all, I examined some growth conditions to form bacterial biofilm in vitro, using Enterococcus faecalis and Porphyromonas gingivalis. Then I tried to make bacterial biofilm in rat's root canal under the growth condition in vivo. As the result, I could not find any bacteria in all samples. I think that the cause was uncertain pulpectomy. Many immunity charge cells left in every root canal were killed all of bacteria. I suppose that biofilm formation in rat's root canal in vivo need continuous infection from bacterial flora.
