Stress analysis of maxillary central incisors endodontically -treated with varying ferrule heights and three different post dowel materials - a finite element analysis

J. oral res. (Impresa); 8 (2), 2019
Statement of problem : fracture of endodontically treated teeth is reduced by the use of a post with ferrule, but the effect of different ferrule configurations and dowel materials is not clear. Purpose: to evaluate the effect of ferrules with different configurations and heights on the stress of endodon...

Resistencia a la Fractura de Dientes Tratados Endodónticamente Obturados con Selladores Biocerámicos Versus Selladores Resinosos. Revisión Sistemática

RESUMEN: El objetivo de este estudio fue determinar mediante la revisión de la literatura científica disponible cuál es el tipo de cemento sellador que proporciona mayor resistencia a la fractura en dientes tratados endodónticamente, los cementos a base de biocerámicos o los en base a resina epóxic...

Volume and/or time of naocl influences the fracture strength of endodontically treated bovine teeth

Braz. dent. j; 30 (1), 2019
Abstract The aim of this study was to evaluate whether amplifying the volume and/or time of contact of NaOCl affects the fracture strength of endodontically treated bovine teeth. Four bovine incisors from 10 animals were allocated into 4 groups using a split-mouth design. Root canals were instrumented us...

New material perspective for endocrown restorations: effects on mechanical performance and fracture behavior

Abstract The aim of this study was to investigate the mechanical performance and the fracture behavior of endocrown restorations prepared using distinct restorative materials. A total of 42 sound molars with similar crown size and shape were cut at 2 mm above the cementoenamel junction and endodontically...

Colagem de fragmentos: uma alternativa de reparo para fraturas dentárias - revisão de literatura
Dental bonding fragments: a repair alternative for tooth fractures – Literature review

Rev. Salusvita (Online); 38 (2), 2019
Introdução: fraturas coronárias de dentes anteriores são frequentemente observadas, tanto em crianças, quanto em adolescentes, devido à posição desses elementos na cavidade oral serem bastante vulneráveis. Em virtude disso, a colagem de fragmentos surge como uma alternativa viável de reparo dos...

Assessment of a conservative approach for restoration of extensively destroyed posterior teeth

J. appl. oral sci; 27 (), 2019
Abstract Extensive restorations in posterior teeth always bring doubts to the clinicians regarding the best protocol, mainly when structures of reinforcement were lost. Objective This study aimed to evaluate the effect of beveling on the fracture resistance and pattern of class II (MOD) restored teeth....

Effect of aging on dentinal crack formation after treatment and retreatment procedures: a micro-ct study

Braz. dent. j; 29 (6), 2018
Abstract In order to evaluate the volume of dentinal cracks taking into account the age of the dentin and the type of file system used for endodontic procedures, forty freshly extracted single-rooted lower incisive teeth presenting similar root volume, were divided into two groups according to the age of...

Efeito do hipoclorito de cálcio na resistência de adesão do cimento obturador AH Plus à dentina

RFO UPF; 23 (2), 2018
Objetivo: avaliar o efeito do uso de hipoclorito de cálcio (Ca(OCl)2) como irrigante na resistência de adesão do cimento AH Plus (De Trey-Dentsply, Konstanz, Alemanha) à dentina pelo teste de micro push-out. Materiais e método: trinta e três dentes humanos monorradiculares foram seccionados transve...

Light curing resin cements containing iodonium salts promote suitable apical bonding of posts to radicular dentin

Abstract The aim of this study was to analyze the efficiency of experimental light-curing resin cements (ERCs) with a ternary photo-initiator system containing diphenyliodonium hexafluorphosphate (DPI) and different amines on retention of glass-fiber posts to dentin (GFP). ERCs formulations: a 1:1 mass r...
