Antimicrobial effect of Rosa damascena extract on selected endodontic pathogens.

The purpose of this study was to compare the antimicrobial activity of a plant-derived extract (2 percent Rosa damascena extract) with 5.25 percent sodium hypochlorite (NaOCl) and 2 percent chlorhexidine (CHX) on selected endodontic pathogens. The minimum inhibitory concentrations (MICs) of 2 percent rose extract and 2 percent CHX for test microorganisms, except F. nucleatum, were lower than that of 5.25 percent NaOCl. All solutions were able to kill all test microorganisms after one minute.
