Background: The oral route is one of the main portals for Helicobacter pylori transmission. elimination this bacterial species from cavity might be useful in health and decreasing infections due to H. pylori. This study aimed evaluate effect a liquorice-extract-containing mouthwash at different concentrations on proliferation vitro. Methods: was cultured, isolated strains specific culture medium were prepared welling procedures. liquorice (Glycyrrhiza glabra) 12.5% 25% added case group wells 1,1/2,1/4,1/8, 1/16 dilutions. In control group, regular daily containing cetylpyridinium chloride sodium fluoride components used. growth inhibition zones analyzed groups. data by SPSS reported using descriptive statistics (means±standard deviation). Results: both mouthwashes concentration, means 1, 1/2, 1/4, 1/8, dilutions larger than those group. Further, largest zone seen with undiluted mouthwash. There no significant differences between (P=0.14). Conclusions: Mouthwashes extracts inhibited more significantly extract. Therefore, it suggested that extract-containing used prevent clinical studies.
