AIMS To investigate how the interfacial shear strength of the dentin-post interface with and without defects changes for different combinations irrigant/sealer. METHODS In forty human decoronated and instrumented teeth, fibreglass posts were inserted. The obtained root segments were randomly assigned to four different groups according to the irrigant adopted and the cement used to seal the ro...

Purpose: This study evaluated the influence of surface treatments on the microtensile bond strength between a glass fiber post surface and resin cements. Methods: Forth-five posts (Reforpost, Angelus, Londrina, PRBrazil) were assigned to three groups with different surface treatment: Group 1: No treatment and silane application only (G1); Group 2: immersion in 96% ethyl alcohol for 10 minutes f...

OBJECTIVE This study investigated the effect of different endodontic irrigant solutions and resin cement systems on the bond strength of cemented fiber posts. METHODS Sixty human single-rooted anterior teeth were sectioned transversely at 2 mm incisal to the cemento-enamel junction (CEJ). The roots were treated endodontically, and teeth were distributed into six groups: group A, includes 5.25...

INTRODUCTION The aim of this in vitro study was to evaluate the effect of various irrigants on the push-out bond strength of calcium-enriched mixture (CEM) cement and mineral trioxide aggregate (MTA). METHODS AND MATERIALS A total of 140 dentin disks with a thickness of 1.5±0.2 mm and lumen size of 1.3 mm, were randomly divided into 12 groups (n=10) and 4 control groups (n=5). The lumen of di...

Introduction: To evaluate the effects of using sodium hypochlorite irrigant on pull-out bond strength of self-etch and self-adhesive resin cements to dentin. Methods: Sixty intact premolars were decoronated and the root canals were prepared by step-back technique. The teeth were divided into two groups according to the irrigant used during root canal treatment: 5.25% sodium hypochlorite and nor...

An endodontic post is required to retain and support the core restoration in case of insufficient remaining coronal dentin after root canal therapy. This study analyzed biomechanical thermal behavior PEEK prefabricated choosing head design that produces least amount stress on tooth structure. These results were compared with most common commercially available post, which titanium glass fiber po...

Due to the carious processs peripheral destruction and endodontic treatments central destruction, majority of endodontically treated teeth are structurally compromised weaker. In an effort strengthen tooth a post was placed hold core material in place when there not enough clinical crown left. Thus main Aim : our study compare evaluate efficacy three different luting cements these materials pla...

AIM This study used a modified tooth-clearing technique to allow observation of accessory canals following filling with a warm gutta-percha technique and one of two endodontic cements. METHODOLOGY Ten extracted human maxillary molars with three roots were selected and divided into two equal groups of five teeth. Each group had 15 canals. Root canal preparation was performed with a modified do...

Mineral trioxide aggregate (MTA) cement is widely used in the field of endodontic treatment. We herein synthesized calcium silicates from carbonate and silicon dioxide, with aim reducing cost associated MTA. Additionally, we prepared gypsum-containing silicate to reduce setting time while enhancing mechanical strength. evaluated physical properties this investigated response human dental pulp s...
