Acción antimicrobiana in vitro de distintas medicaciones sobre Enterococcus faecalis y Actinomyces israelii

Objective: To compare in vitro antimicrobial effect of different root canal medicaments on Enterococcus faecalis and Actinomyces israelii. Methodology: The agar diffusion test was used to assess the bacterial growth inhibition zones achieved with different antibiotic pastes, including a metronidazole- containing paste (Grinazole ® ), a combination of dexamethasone, tyrothricin and both polymyxin and neomycin sulfate (Septomixine forte ® ), calcium hydroxide (Calcipulpe ® ), and camphorated paramonochlorophenol (Kri-3 ® ) against E. faecalis and A. israelii. Results: Antibacterial inhibition against E. faecalis was significantly (P<0.05) greater with Septomixine forte ® (30.7 mm) followed by Kri-3 ® (22.5 mm), Calcipulpe ®
