Influência da patência apical na adaptação do cone principal de obturação. Análise por tomografia computadorizada de feixe cônico

Procedimentos como a patência apical podem influenciar diretamente na adaptação do cone principal de guta-percha, provocando um maior desgaste e deixando espaços vazios maiores, o qual poderia comprometer o sucesso do tratamento endodôntico. Por isso, o objetivo do presente estudo foi avaliar por me...

Revisión de desobturación de gutapercha con limas manuales, Xilol y Reciproc

Odontoestomatol; 20 (32), 2018
El tratamiento endodóntico no quirúrgico es de primera elección en el caso de fracasos endodónticos. El primer paso del retratamiento es la desobturación del conducto radicular, que va a permitir la preparación biomecánica del conducto radicular con irrigación y desinfección correcta. El protoco...

Obturación del sistema de conductos radiculares: revisión de la literatura
Root canal system obturation: a review of the literature

Rev. ADM; 75 (5), 2018
Con el paso de los años, diferentes conceptos atribuidos a temáticas del área de la endodoncia sufren modificaciones. Una de estas etapas es la obturación del sistema de conductos radiculares, este procedimiento sumamente minucioso y crítico en la obtención de un resultado exitoso ha tenido en los ...

Contamination of gutta-percha cones in clinical use by endodontic specialists and general practitioners

ABSTRACT. Introduction: the present study evaluated the microbial contamination of gutta-percha cones proceeding from packages used clinically by endodontic specialists and general practitioners. Methods: two gutta-percha cones were selected from 30 original packages, already in clinical use, in dent...

Influência do cimento na radiopacidade de obturações com cone único
Sealer influence on radiopacity of single cone root canal fillings

Dent. press endod; 7 (2), 2017
Objetivo: o objetivo deste estudo foi avaliar a influência dos cimentos AH Plus e Endofill na radiopacidade de obturações em canais simulados, usando-se a técnica do cone único. Métodos: vinte blocos de resina com canais curvos simulados foram preparados até o instrumento rotatório ProTaper Univ...

Efeito de diferentes sistemas de obturação na resistência à fratura de raízes tratadas endodonticamente

Braz. dent. sci; 20 (1), 2017
Objective: This study aimed to compare the fracture resistance of endodontically treated roots filled by different obturation systems. Material and methods: Ninety-six maxillary central incisors were used and decoronated, retaining 12 mm of the roots. On the basis of obturation systems, the roots were ra...

Influence of solvents on the bond strength of resin sealer to intraradicular dentin after retreatment

Abstract This study evaluated the removal of filling material with ProTaper Universal Rotary Retreatment system (PTR) combined with solvents and the influence of solvents on the bond strength (PBS) of sealer to intraradicular dentin after canal reobturation. Roots were endodontically treated and distribu...

Evaluation of the physicochemical properties of silicone- and epoxy resin-based root canal sealers

Abstract To assess the physicochemical properties of AH Plus, GuttaFlow 2, GuttaFlow BioSeal, and MM Seal, five samples of each root canal sealer were evaluated to determine their setting time (ST), dimensional change (DC), solubility (SL), flow (FL), and radiopacity (RD) according to American National S...

Materials used for indirect pulp treatment in primary teeth: a mixed treatment comparisons meta-analysis

Abstract: This study aimed to systematically review the literature to address the question regarding the influence of different materials in the clinical and radiographic success of indirect pulp treatment in primary teeth. A literature search was carried out for articles published prior to January 2017 ...

Effect of rewetting solutions on micropush-out dentin bond strength of new bioceramic endodontic material

Abstract To evaluate the influence of rewetting solutions on bond strength to root dentin of conventional gutta-percha (GP) or niobium phosphate glass-based gutta-percha (GNb) associated with a bioceramic sealer. The root canals of 80 human mandibular premolars were prepared using nickel-titanium instrum...
