Methods: Seven different propolis drops (Group 1 to 7: UmayHerbal Organic Propolis, Bee'o Up [15%], Propoli EVSP, BrazilianGreen Liquid Propolis, Eğriçayır Propolis, Bee'o Up [30%],Biostore Propolis) were included in the study. Antimicrobial effectof drops was investigated by the agar plate diffusion method. Petridishes were prepared with Brain-Heart Infusion broth. 100 µl ofmicroorganisms and 10 µl of each propolis were planted to thesepetri dishes from a broth culture. Inhibition zones formed on the24th hour were measured in mm's and each experimental groupwas photographed. Data were compared by Mann Whitney-U test. Results: Only water-based propolis of the present study (Group1) formed no inhibition zone against both oral pathogens andalcohol-based groups 4 and 5 formed no zone only against thelatter. Group 5 showed significantly the highest antimicrobial effectagainst S. mutans, however that group showed no influence on E.faecalis. Group 6 was found significantly more effective on E.faecalis than other propolis drops (p<0.05). Conclusion: All of the groups showed antimicrobial effect oneither one of the oral pathogens except for the water-basedpropolis drop. Compared to E. faecalis, tested propolis drops hadaffected S. mutans more. Thus, propolis extracts could be used asa more natural and harmless prevention method to dental cariesspecifically.eninfo:eu-repo/semantics/openAccessTıbbi Araştırmalar DeneyselDiş HekimliğiMikrobiyolojiArticle83673678504427
