Diagnóstico, planificación del tratamiento y endodoncia de un primer premolar inferior con dos canales mediante tomografía computarizada 3D: reporte de un caso

J. oral res. (Impresa); 7 (9), 2018
El tratamiento endodóntico debe considerar que los dientes presentan una morfología del sistema de canales radiculares con alta variabilidad y complejidad. por lo tanto, el conocimiento acabado de la anatomía radicular y la planificación del procedimiento utilizando sistemas imagenológicos previos a...

Current options concerning the endodontically-treated teeth restoration with the adhesive approach

Braz. oral res. (Online); 32 (supl.1), 2018
Abstract: Adhesive procedures have changed the way to restore endodontically treated teeth (ETT). It started with the shift from cast post-and-core to fiber post. The original focus on strength also shifted towards failure modes, revealing that catastrophic failures are still a concern when restoring end...

How to improve root canal filling in teeth subjected to radiation therapy for cancer

Abstract The aim of this study was to evaluate the influence of radiation therapy on root canal sealer push-out bond strength (BS) to dentin and the sealer/dentin interface after different final irrigation solutions (NaOCl, EDTA, and chitosan). Sixty-four maxillary canines were distributed into two group...

Immediate tooth replantation: root canal filling for delayed initiation of endodontic treatment

Abstract The aim of this study is to evaluate the action of paramonochlorophenol associated with Furacin followed by calcium hydroxide (CH) dressing in the control of inflammatory root resorption in cases of immediate tooth replantation with delayed endodontic treatment. A total of 28 incisors of 3 male ...

Evaluation of the sealing ability of different root canal sealers: a combined SEM and micro-CT study

J. appl. oral sci; 26 (), 2018
Abstract Objective: The purpose of this study was to analyze the ability of multiple compounds to seal the dental tubules using scanning electron microscopy (SEM) and micro-computed tomogra-phy (micro-CT). Material and Methods: Twenty-four single-root human mandibular premolars were selected and instru...

Incidencia y tipo de istmos en primeros molares permanentes humanos, evaluación in vitro

Int. j. morphol; 35 (4), 2017
RESUMEN: El conocimiento de la complejidad anatómica del sistema radicular de conductos generada por conductos accesorios, deltas apicales e istmos, aumenta la probabilidad de éxito en el tratamiento endodóntico, dado que dichos sitios pueden ser un reservorio de microorganismos y materia orgánica qu...

Estabilizador Endodóntico en Fractura Complicada de Raíz en visita única
Endodontic Stabilizer in Complicated Root Fracture in a single visit

Introducción: La fractura complicada de raíz del tercio medio es una entidad compleja de pronóstico mayormente desfavorable y curso sintomático, donde el éxito clínico en no pocas oportunidades se convierte en una utopía, dado que la estabilidad en el afrontamiento de los bordes libres de los frag...

Influence of elastic modulus of intraradicular posts on the fracture load of roots restored with full crowns

Objective: This study aimed to evaluate the fracture load and displacement of roots restored with posts of different elastic modulus. Material and method: Thirty-six replicas of epoxy resin mixed with glass microfibers were made from an endodontically-treated human premolar root prepared to a length of...

Diagnosis of alveolar and root fractures: an in vitro study comparing CBCT imaging with periapical radiographs

J. appl. oral sci; 25 (2), 2017
Abstract Objective To compare periapical radiograph (PR) and cone-beam computed tomography (CBCT) in the diagnosis of alveolar and root fractures. Material and Methods Sixty incisor teeth (20 higid and 40 with root fracture) from dogs were inserted in 60 anterior alveolar sockets (40 higid and 20 wit...

Root and canal morphology of permanent mandibular incisors

There are no studies in the literature reporting the prevalence of root canal ramifications in samples of lower incisors in the population of northern Brazil. The knowledge of the usual endodontic morphology and its possible anatomical variations is important. The aim of this study was to evaluate the pr...
