From: No-ozone cold plasma can kill oral pathogenic microbes in H2O2-dependent and independent manner
The bactericidal effect of NCP mounted with dental tips is dependent on the pore size and the length of tips. (A) Total 7 kinds of dental tips that can be mounted on NCP device were prepared. Left panel a photograph showing the appearance of 7 tips. Right panel a table showing specific information of the tips. (B) S.mutans samples on solid medium were subjected to NCP treatment for 5 min in unmounted or mounted with 7 kind of tips respectively. Upper panel A photographs showing a clear zone formed by 5 min of NCP treatment. Bottom panel: a graph showing the size of a clear zones. (C) The H2O2 level change of 2 ml of liquid medium after NCP treatment mounted with 7 kinds of dental tips. Data shown are the average of three independent experiments, **< 0.01.
