Phytochemical and biological study of phenolic components from Geoffroea decorticans stem bark

The stem bark of Geoffroea decorticans (Gill.ex Hook. etArn.) Burk. was used medicinally to cure several skin affections; however, phytochemical and biological antecedents were not found. Analyses of purified methanolic extract from G. decorticans bark (PFGB), realized by silylation d...

Efecto antimicrobiano in vitro de extractos de Caesalpinia Spinosa (algarrobo) sobre patógenos orales

La resistencia antimicrobiana es un problema de sa-lud pública mundial. Las infecciones por microorga-nismos resistentes pueden ser altamente transmisi-bles e incluso causar la muerte. Este hecho genera grandes costos para los pacientes y para los servi-cios de salud. El objetivo del presente trabajo fu...

Comparación de la efectividad antimicrobiana entre hipoclorito de sodio 2, 5% y ácido hipocloroso 5% frente a Enterococcus faecalis: prueba in vitro
Comparison of antimicrobial effectiveness between sodium hypochlorite 2.5% and hypochlorous acid 5% against Enterococcus faecalis: an in vitro test

La terapia endodóntica tiene como uno de sus objetivos lograr la completa desinfección del sistema de conductos radiculares. Por esto, se deben seleccionar sustancias irrigantes que tengan la capacidad de eliminar todo el contenido de dicho sistema. La acción antimicrobiana es una de las característi...

Influence of EDTA and its Association with Benzalkonium Chloride on Enterococcus faecalis Adhesion to Dentin

ABSTRACT: The aim of this in vitro study was to investigate the influence of ethylenediaminetetraacetic acid (EDTA) associated with the benzalkonium chloride (BAK) on the adhesion and formation of Enterococcus faecalis biofilms attached to coated dentin. Discs standard bovine dentin blocks were treated w...

Purpose: evaluate the antimicrobial activity of intracanal dressings and their influence on dentinal colour changes. Material and methods: eighty single-rooted human extracted teeth were decoronated and divided into eight groups (n=10) according to intracanal dressing protocols inserted into the root can...

Effect of a calcium hydroxide-based intracanal medicament containing N-2-methyl pyrrolidone as a vehicle against Enterococcus faecalis biofilm

J. appl. oral sci; 28 (), 2020
Abstract This study investigated the effect of a calcium hydroxide (CH) paste (CleaniCal®) containing N-2-methyl pyrrolidone (NMP) as a vehicle on Enterococcus faecalis (E. faecalis) biofilms compared with other products containing saline (Calasept Plus™) or propylene glycol (PG) (Calcipex II®). ...

Influencia de la dentina en el efecto antibacteriano de 2 concentraciones de hipoclorito de sodio en el crecimiento de Enterococcus faecalis ATCC 29212

Este estudio in vitro evaluó la influencia de la dentina sobre el efecto antibacteriano contra Enterococcus faecalis ATCC 29212 de dos concentraciones de Hipoclorito de Sodio (NaOCl) 2,5 % y 5 %. Se empleó polvo de dentina a partir de dientes humanos (84 µg/ml) y la supervivencia de la bacteria se eva...

Antibiotic resistance of Enterococcus faecalis from persistent endodontic infections

Enterococci are important nosocomial pathogens due to their intrinsic multiresistance and the acquisition of new antibiotic resistance genes (ARG). Enterococcus faecalis has been shown to be one of the main pathogens in persistent endodontic infections, therefore, the main objective of this study was to ...

Role of extracellular DNA in Enterococcus faecalis biofilm formation and its susceptibility to sodium hypochlorite

J. appl. oral sci; 27 (), 2019
Abstract Objective This study investigated the role of extracellular deoxyribonucleic acid (eDNA) on Enterococcus faecalis ( E. faecalis ) biofilm and the susceptibility of E. faecalis to sodium hypochlorite (NaOCl). Methodology E. faecalis biofilm was formed in bovine tooth specimens and the biofilm ...
