Aim: To evaluate the resistance of union between a glass fiber post and radicular dentine after cleaning root with 17% EDTA filling different endodontic cements. Methods: Forty uniradicular bovine incisors were removed to obtain lengths 18 mm. Endodontic treatment was performed on all roots using cements (zinc oxide eugenol-based, OZE; cement based epoxy resin, AH) solutions (saline, SA or EDTA...

INTRODUCTION Particle size and distribution can influence the properties of materials. This study analyzed and compared the particle size of Root MTA, calcium hydroxide (CH), and a new endodontic cement called calcium enriched material (CEM). MATERIALS AND METHODS The particle size of each material was analyzed three times using 0.05 mg of test material with a particle size analyzer. The part...

INTRODUCTION Some studies in dental literature have proposed that short term and long term exposure of root dentin to calcium hydroxide predisposes it to fracture. Mineral trioxide aggregate (MTA) and a recently introduced endodontic material, calcium-enriched mixture (CEM) cement may be used instead of calcium hydroxide and might have an effect on the strength of root dentin. Therefore, the ai...

introduction: this in vitro study aims to evaluate the coronal and apical sealing ability of gutta-percha (gp) root filling used with either mineral trioxide aggregate (mta), new endodontic cement (nec) or ah26 as filler/sealers. materials and methods: forty eight single-rooted extracted teeth were selected, decoronated and then instrumented. samples were randomly divided into three experimenta...

Fiber reinforced composite (FRC) posts are commonly used by clinicians in post-endodontic restorations, mostly due to their favorable physical properties, i.e. the modulus of elasticity close to that of dentin (1). Yet, clinical failures involving endodontically treated teeth reconstructed with FRC posts could occur and are mainly attributed to cementation flaws (2). The design and composition ...

AIM To compare posts of different flexibility using static load testing. Hypotheses tested were (1) the flexural modulus of endodontic posts does not show a linear relationship with failure load and (2) the flexural modulus of endodontic posts does not show an association with failure mode. METHODOLOGY Thirty 2 mm diameter rods of a glass fibre material Aesthetiplus (A), a carbon fibre Compos...

BACKGROUND AND AIM Bioceramics are ceramic compounds obtained both in situ and in vivo, by various chemical processes. Bioceramics exhibit excellent biocompatibility due to their similarity with biological materials, like hydroxyapatite. Bioceramics and multi-substituted hydroxyapatite or similar compounds have the ability to induce a regenerative response in the organism. The aim of this paper...

AIM To report the endodontic treatment of an immature maxillary central incisor with dens invaginatus. SUMMARY Dens invaginatus is a rare malformation of teeth, probably resulting from an infolding of the dental papilla during tooth development. The present case describes the complex endodontic treatment of a type III dens invaginatus in an immature maxillary central incisor with a necrotic p...

an important factor that interferes with the bonding between the root canal wall and resin cement is the root canal sealer remnant. there is controversy about the effect of eugenol-containing sealers on the bond strength between resin cements and fiber post. the aim of this study was to evaluate the effect of the type of endodontic sealer on the bond strength of frc posts cemented with resin ce...
