Efficacy of Chlorine Dioxide as an Endodontic Irrigant for Pulp Dissolution in vitro

Determine the efficacy of 5 % chlorine dioxide as an endodontic irrigant for pulp dissolution. Thirty five samples of human dental pulp were obtained, previously weighed and immersed in three solutions= 5 % ClO 2, 5.25 % NaOCl and saline (control group), for 10 minutes at 32 ºC; they were dried and rewe...

Comparação da propriedade antimicrobiana da clorexidina e do hipoclorito de sódio como irrigantes endodônticos: revisão integrativa

Rev. Ciênc. Plur; 8 (3), 2022
Introdução:Durante o tratamento endodôntico, devido às complexidades anatômicas dos canais radiculares, a ação mecânica dos instrumentos não é suficiente para a completa desinfecção dos condutos. Dessa forma, se faz necessário o uso de soluções irrigadoras que possampotencializ...

Irrigación Activada por Láser en Endodoncia

El objetivo de la endodoncia es prevenir o curar la periodontitis apical. Por lo tanto, los microorganismos que han colonizado el sistema de canales radiculares deben ser eliminados para promover la regeneración y cicatrización. Desafortunadamente, la existencia de canales accesorios, anastomosis, istm...

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...

Penetration degree of sealer in artificial lateral canal after passive ultrasonic irrigation with EDTA for different times

Acta odontol. latinoam; 32 (2), 2019
The aim of this study was to evaluate the degree of penetration of obturation cement in artificial lateral canals after Passive Ultrasonic Irrigation (PUI) with ethylenediaminetetraacetic acid (EDTA) for different times. Fifty upper molar palatine roots were used, in which two artificial lateral canals w...

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 ...

Influence of surfactants addition on the properties of calcium hypochlorite solutions

J. appl. oral sci; 27 (), 2019
Abstract Objectives The aim of this study was to evaluate the influence of surfactants 0.2% or 0.1% cetrimide (Cet) or 0.008% benzalkonium chloride (BAK) on 2.5% calcium hypochlorite (Ca(OCl)2), and compare to sodium hypochlorite (NaOCl), regarding the properties of pH, free chlorine content, surface te...

Antibacterial efficacy of synthetic and natural-derived novel endodontic irrigant solutions

Braz. dent. j; 29 (5), 2018
Abstract The aim of this study was to compare the efficacy of grape seed extract (GSE), calcium hypochlorite [Ca(ClO)2], and sodium hypochlorite (NaOCl) irrigant solutions with rotary or reciprocating instrumentation for disinfection of root canals inoculated with Enterococcus faecalis. The mesiobuccal r...

Demetallization of Enterococcus faecalis biofilm: a preliminary study

J. appl. oral sci; 26 (), 2018
Abstract Objectives To determine the concentration of calcium, iron, manganese and zinc ions after the application of chelator to Enterococcus faecalis biofilms. Material and Methods Fifty bovine maxillary central incisors were prepared and inoculated with E. faecalis for 60 days. The following were ...

Efficacy of relacin combined with sodium hypochlorite against Enterococcus faecalis biofilms

J. appl. oral sci; 26 (), 2018
Abstract Objective Relacin is a synthetic molecule that targets RelA, an essential protein in a conserved bacterial stress response system. It was shown to inhibit bacterial growth. The aims of this study were to evaluate the antimicrobial effect of relacin combined with sodium hypochlorite (NaOCl) on ...
