Irrigation protocols effects on radicular dentin: Cleaning, disinfection and remaining ultrastructure

Odovtos (En linea); 25 (1), 2023
A successful endodontic treatment requires a combination of satisfactory mechanical instrumentation, adequate irrigation protocols, and three-dimensional obturation of the canal system. Irrigation is considered the most critical procedure to ensure cleaning and disinfection. To date, a large variety of i...

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...

Effects of dentinary contamination by endodontic irrigants on bonding strength of adhesive systems

J. res. dent; 10 (1), 2022
This study aimed to evaluate if 2.5% sodium hypochlorite compromises the adhesion of bonding materials. The factors in the study were the irrigation solutions in two levels: 2.5% sodium hypochlorite and saline solution; and the adhesive systems used in three levels: three-step adhesive, universal adhesiv...

Evaluation of the dentinal tubule penetration of an endodontic bioceramic sealer after three final irrigation protocols

J. res. dent; 10 (1), 2022
Introduction: This study aimed to evaluate the dentinal tubule penetration of an endodontic bioceramic sealer, Sealer Plus BC, after three final irrigation protocols. Methods: Thirty distobuccal roots of maxillary molars were selected. Root canal preparation was performed up to an #40.06 instrument (X1 B...

Bioseguridad en el laboratorio dental
Biosafety in the dental laboratory

Una enfermedad infecciosa es aquella producida por un agente infeccioso (bacterias, hongos, virus, etc.) que ingresa y se desarrolla en el organismo de un hospedero. Posteriormente, puede trasmitirse de un individuo a otro directamente por contacto entre ambos, o bien, indirectamente, por medio de un vec...

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...

Determination of sodium hypochlorite concentrations in the activation of the irrigant by passive technique with ultrasonic, during the ex vivo endodontic protocol

ABSTRACT: Introduction: Sodium hypochlorite and ultrasonic activation have a synergistic and improving effect on canal disinfection. Some authors found irrigant decrease after activation with ultrasonic, while others described an increased concentration in later stages. The aim of this study was to deter...

Sellado marginal aplicando hipoclorito de sodio versus ácido fosfórico como acondicionador dental

Rev. cuba. estomatol; 57 (1), 2020
RESUMEN Introducción: La microfiltración es uno de los problemas principales de todas las obturaciones a base de resina. Muchos estudios buscan optimizar un buen sellado marginal utilizando diversos acondicionadores, como el hipoclorito de sodio, que permite que el adhesivo penetre bien, al generar de...

Effect of passive ultrasonic activation on microorganisms in primary root canal infection: a randomized clinical trial

J. appl. oral sci; 28 (), 2020
Abstract Objective: This clinical study sought to evaluate the effectiveness of passive ultrasonic activation (PUA) in eliminating microorganisms in primary endodontic infection (PEI) after instrumentation of root canals using microbiological culture and checkerboard DNA-DNA hybridization. Methodology:...

Effectiveness of XP-Endo Finisher in the reduction of bacterial load in oval-shaped root canals

Abstract: This study investigated the effectiveness of XP-Endo Finisher (XPF) associated with XP-Endo Shaper (XPS) or Reciproc Blue (RB) files in reducing bacterial load in oval-shaped root canals (RC) during chemomechanical preparation (CMP) using 0.9% saline solution (NaCl) or 2.5% sodium hypochlorite ...
