Análisis de 117 episodios de bacteriemia por enterococo: estudio de la epidemiología, microbiología y sensibilidad a los antimicrobianos
Analysis of 117 episodes of enterococcal bacteremia: Study of epidemiology, microbiology and antimicrobial susceptibility

Rev. argent. microbiol; 48 (4), 2016
La bacteriemia por Enterococcus adquirió un papel relevante en los últimos años, debido al incremento de casos intrahospitalarios. Nuestro objetivo fue describir los episodios ocurridos en pacientes adultos de nuestro hospital. Entre enero del 2000 y diciembre del 2013 se registraron 117 episodios. El...

Efecto del cemento endodóntico modificado con antibióticos en la reducción in vitro de enterococcus faecalis
Effect of cement endodontic modified antibiotics in reduction invitro of enterococcus faecalis

Evid. odontol. clín; 2 (2), 2016
Introducción: determinar el efecto del cemento endodóntico Apexit plus combinado con 5 antibióticos por separado contra el enterococcus faecalis, bacteria resistente y asociada directamente al fracaso endodóntico. Materiales y Método: Se utilizarón cepas de Enterococcus faecalis ATCC 29212, las cua...

Exopolysaccharide dispelled by calcium hydroxide with volatile vehicles related to bactericidal effect for root canal medication

J. appl. oral sci; 24 (5), 2016
ABSTRACT Objective: Enterococcus faecalis is the dominant microbial species responsible for persistent apical periodontitis with ability to deeply penetrate into the dentin. Exopolysaccharides (EPS) contribute to the pathogenicity and antibiotic resistance of E. faecalis. Our aim was to investigate the ...

Actividad antibacteriana y antifúngica de un extracto de Salvia apiana frente a microorganismos de importancia clínica
Antibacterial and antifungal activity of Salvia apiana against clinically important microorganisms

Rev. argent. microbiol; 48 (3), 2016
Debido a la gran problemática mundial de la resistencia bacteriana a los antibióticos, es necesaria la búsqueda continua de nuevas moléculas con características antimicrobianas. Este estudio evaluó el efecto antibacteriano y antifúngico de un extracto hexánico proveniente de la raíz de Salvia ap...

Effect of addition of nano-hydroxyapatite on physico-chemical and antibiofilm properties of calcium silicate cements

J. appl. oral sci; 24 (3), 2016
ABSTRACT Objective Mineral Trioxide Aggregate (MTA) is a calcium silicate cement composed of Portland cement (PC) and bismuth oxide. Hydroxyapatite has been incorporated to enhance mechanical and biological properties of dental materials. This study evaluated physicochemical and mechanical properties a...

Estudo da capacidade fagocítica de macrófagos humanos frente a diferentes cepas de Enterococcus faecalis

Enterococcus faecalis (E. faecalis) é um microrganismo presente em lesões endodônticas persistentes, mostrando maior resistência do que outras bactérias ao Hidróxido de Cálcio, um medicamento alcalino que consegue eliminar diversos microrganismos durante o tratamento endodôntico. Assim, os...

Influência da agitação do hipoclorito de sódio como protocolo de irrigação final quanto à atividade antibacteriana no sistema de canais radiculares

Diferentes manobras para promover agitação do hipoclorito de sódio têm sido propostas para incrementar a desinfecção do sistema de canais radiculares (SCR). O objetivo deste trabalho foi comparar, ex vivo, diferentes formas de agitação do NaOCl usado na irrigação final do SCR, avaliando a mais ...

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...

Antimicrobial activity and substantivity of Uncaria tomentosa in infected root canal dentin

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of this study was to analyze the antimicrobial activity and substantivity of Uncaria tomentosa Willd DC (cat's claw, CC) in root dentin contaminated with Enterococcus faecalis. Forty-eight human premolars were contaminated with E. faecalis (ATCC 29212) and randomly divided into four grou...
