Abstract:
Objective: To examine effects of Platycodon grandiflorum (JG), Glycyrrhiza uralensis Fisch (GC) or the compound of JG with GC on the growth of cariogenic and periodontopathic bacteria in vitro . Methods: JG,GC and the compound were extracted with ?=65% ethanol respectively. The minimal inhibitory concentration(MIC)and minimal bactericidal concentration (MBC) of JG, GC or compound against S.mutans MT818, S. sobrinus 6715, P.gingivalis 381 and B.forsythus 43037 were measured by drug sensetivity test.Results: JG showed no effect on the growth of oral pathogens tested;GC inhibited S.mutans MT 8418 and S.sobrinus 6715 with MIC of 3.91 mg/ml.The compound inhibited the microorganisms with the MIC of 1.96 mg/ml against S.mutans MT8148 or S.sobrinus 6715, 3.91 mg/ml against P.gingivalis 381, 7.81 mg/ml against B.forsythus 43037 respectively.Conclusion: The compound of JG and GC has stronger inhibition and bactericidal effects on oral pathogens than the single medicine.
