Abstract:
Objective:To evaluate the antimicrobial effect of ozonated water on the putative periodontopathic bacteria.Methods:Pophyromonas gingivalis (P.g)ATCC33277,Haemophilus actinomycetemcomitans (H.a)ATCC29522,Fusobacterium nucleatum (F.n)ATCC1 0957 and clinically seperated strain of P.g(C -P.g)were treated by ozonated water with ozone concentration(mg/L) of 0.03,0.06 and 0.1 2 for 30,60,90 and 1 20 s respectively.The bactericidal effect was tested by bactericidal assay.H2 O2 was used as the positive control and distilled water as the negative control.Results:The antimicrobial rate of ozonated water agaist the bacteria increased with the ozone concentration increase.There was no statistic diffrence of the effect on P.g and C -P.g(P >0.05).Linear regression analysis showed that the βvalues of the concentration factor were over 0.95,that of the time factor under 0.1 1 .Conclu-sion:The ozonated water has dose-dependent bactericidal effect on P.g,H.a and F.n.
