INTRODUCTION Many studies have been performed to evaluate the stress distribution around endodontic posts; those which compared posts composed of different materials are rare. The aim of this study was to compare stresses induced in dentin by three structurally different posts using photoelasticity method. MATERIALS AND METHODS Nine blocks of PSM-5 Photoelastic material with 45×45×10 mm dimen...
Glass fiber-reinforced endodontic posts are considered to have favorable mechanical properties for the reconstruction of endodontically treated teeth. The aim of the present investigation was to evaluate the survival of two tapered and one parallel-sided glass fiber-reinforced endodontic post systems in teeth with different stages of hard tissue loss and to identify risk factors for restoration...
This literature review summarizes the recent research on fiber posts and provides information regarding their bonding to resinous cement or composites, based on the results of original scientific full-papers from peer-reviewed journals listed in Pub Med. The search was conducted evaluating the different materials available for luting fiber posts to radicular dentin. A consistent number of in vi...
Background and Objective: Relining fiber posts with flowable composites is a procedure used for strengthening the weak walls of endodontically treated teeth. The aim of this study was to evaluate the effect of relining fiber posts with two types of flowable composites on the fracture resistance of the endodontically treated teeth. Materials and Methods: In this laboratory experimental study, 3...
background and aims. various factors influence the interfacial bond between the fiber posts and root canal dentin. the aim of the present study was to evaluate the effect of pre-warming of resin cement on the push-out bond strength of fiber posts to various segments of root canal dentin. materials and methods. in this in vitro study, 40 single-rooted human premolars were decoronated and underwe...
the aim of this study was to evaluate the effect of cyclic loading on the bond strength of quartz fiber posts to root canal dentin after different surface treatments of different regions of root canal dentin.forty-eight single-rooted human teeth were selected. post spaces were prepared and then the teeth were divided into four groups: g1: no treatment (control); g2: irrigation with a chemical s...
SELECTION CRITERIA The authors searched MEDLINE, EMBASE, CENTRAL, and Scopus electronic databases through 2004 for eligible articles. The authors also searched International Association for Dental Research conference proceedings and abstracts from 1996-2004 and contacted manufacturers and other known experts to identify unpublished studies. Studies had to be randomized or quasi-randomized clini...
AIM To compare the efficacy of resin composite restorations, retained with either polyethylene or zirconia-rich glass fiber posts. METHODS Sixty-two single rooted maxillary and mandibular central incisor teeth in forty-four patients (15 males and 29 females; age range 15-32 years) were restored either with an ultrahigh molecular weight polyethylene (UHMWP) fiber post (Bondable Reinforcement R...
BACKGROUND Post design and material has very important effects on dentinal stress distribution since the post placement can create stresses that lead to root fracture. MATERIALS AND METHODS In this study we use finite element analysis (FEA) to evaluate stress distribution on endodontically treated maxillary central incisors that have been restored with different prefabricated posts. Six model...
This retrospective study evaluated the clinical outcome of 139 teeth restored with carbon fiber posts after 3 years of placement, considering the amount of remaining dentin as the main variable. Eighty-one patients received the fiber posts within a period of 16 months and were recalled after 3 years. The tooth type, amount of remaining dentin, and prosthetic crown material were evaluated. No lo...
