Antimicrobial activity of different disinfectants against cariogenic microorganisms

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of this study was to assess the in vitro antimicrobial effects of chlorhexidine digluconate (CHX), polyhexamethylene biguanide (PHBM), and octenidine dihydrochloride (OCT) on cariogenic microorganisms by using their minimum inhibitory concentration (MIC) and minimum bactericidal concentr...

In vitro antibacterial activity of a silicone-based endodontic sealer and two conventional sealers

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of this study was to evaluate whether the modification in the silver component is capable of providing GuttaFlow 2 with antibacterial activity against Enterococcus faecalis compared with epoxy resin-based (AH Plus) and zinc oxide and eugenol-based (Endofill) sealers. The antibacterial ac...

Antimicrobial action of calcium hydroxide-based endodontic sealers after setting, against E. faecalis biofilm

Braz. oral res. (Online); 30 (1), 2016
Abstract Enterococcus faecalis are gram positive bacteria that can mostly resist endodontic therapy, inducing persistent infection in the root canal system. Endodontic sealers with antimicrobial activity may help eliminate residual microorganisms that survive endodontic treatment. The present study aimed...
