Retratamiento endodóntico no quirúrgico de molar inferior con lesión apical: estrategia terapéutica
Non-surgical endodontic retreatment of a lower molar with an apical lesion: therapeutic strategy

La terapéutica endodóntica se apoya básicamente en dos modelos teóricos o paradigmas: el concepto de “tubo hueco” técnico y quirúrgico esencialmente mecanicista, y el modelo terapéutico para conductos radiculares, que busca la restitución ad integrum de los tejidos apicales y el hueso alveola...

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...

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...

Pulpotomía con biodentine comparado con formocresol en pacientes con dentición primaria

RESUMEN: Introducción: En dentición primaria, la pulpotomía con formocresol ha sido convencionalmente utilizada para el tratamiento de caries cercanas a la pulpa. Sin embargo, la seguridad de este material ha sido cuestionada. Por otro lado, el biodentine ha sido propuesto como un biomaterial sustitut...

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...

Treatment outcomes of pulp revascularization in traumatized immature teeth using calcium hydroxide and 2% chlorhexidine gel as intracanal medication

J. appl. oral sci; 28 (), 2020
Abstract Objective Pulp revascularization is an effective treatment for immature necrotic teeth. Calcium hydroxide has been used in pulp revascularization as an intracanal medication due to its antimicrobial action and the non-exhibition of crown discoloration and cytotoxicity for stem cells from the a...

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:...

Cleaning effectiveness of a nickel-titanium ultrasonic tip in ultrasonically activated irrigation: a SEM study

Abstract In endodontic treatment, regardless of the instrumentation technique, the presence of a smear layer covering contaminated dentin walls is always a concern. Thus, irrigation plays an essential role in reducing bacterial load. To enhance irrigation effectiveness, different ultrasonic activation me...

Irrigation trends among members of the Chilean Endodontic Society

J. oral res. (Impresa); 7 (7), 2018
Introduction: the aim of this study is to determine the current trends of irrigation during root canal therapy by specialists who are members of the Chilean Endodontic Society. materials and method: a survey (survey monkey -SurveyMonkey.com) was e-mailed to the 485 members of the Chilean Endodontic Socie...

Unprepared root canal surface areas: causes, clinical implications, and therapeutic strategies

Braz. oral res. (Online); 32 (supl.1), 2018
Abstract: Chemomechanical preparation is intended to clean, disinfect, and shape the root canal. This step is of utmost importance during treatment of infected teeth with apical periodontitis, because treatment outcome depends on how effectively the clinician eliminates bacteria, their products, and necr...
