Abstract Introduction The correct use of glass fiber posts in endodontically treated teeth is essential for the clinical success of restorative treatment. Objective This study evaluated the push-out shear bond strength of relined (R) or non-relined (NR) glass fiber posts, cemented with self-adhesive resin cement [RelyXTM U100 (U100)] and conventional resin cement [RelyXTM ARC (ARC)]. Material and method Sixty human single-rooted teeth were endodontically treated and divided into ARC-NR; U100-NR; ARC-R; U100-R groups. The teeth were sectioned into cervical, middle and apical thirds, and subject

Abstract:

BACKGROUND Endodontically treated teeth have higher fracture rate due to pronounced coronal destruction. The minimally invasive approach of associating adhesive techniques and posts seems to contribute to a better clinical prognosis for endodontically treated teeth. The purpose of this study was to evaluate the push out bond strength and mode of failure of fiber post using one self-etch resin cement and two selfadhesive resin cements. METHODS Sixty single rooted teeth were selected and decoronated 2 mm coronal to cementoenamel junction (CEJ). The teeth were prepared and obturated, then divided

Luting of fiber posts to intra-radicular dentin represents the worst-case scenario in terms of control of polymerization shrinkage. This study tested the hypothesis that filler content of resin cements does not influence luting of fiber posts to intra-radicular dentin, by assaying polymerization stress, push-out bond strength, and nanoleakage expression. The polymerization stress of experimental cements containing 10%, 30%, 50%, or 70% in filler content was investigated. Post spaces were prepared in endodontically treated teeth, and fiber posts were cemented with the experimental cements. A pu

Each group received irrigation with 1 × 5 mL EDTA (17%) and 3 × 5 mL NaOCl (5.25%). In the first group, the irrigants were not activated, while in the second and third group, LAI was adopted using PIPS

The maxillary incisors are most severely affected, with deep carious lesions usually involving the pulp. Teeth that have been endodontically treated often have little coronal tooth tissue remaining and as such require a post to retain the core and restoration .This study evaluated and compared the efficacy of EverStick glass fiber-reinforced composite post with ParaPost Taper Lux

Introduction: Fiber-reinforced composite posts (FRCP) have become popular due to their multiple advantages in teeth with extensive crown destruction. Proper disinfection is essential for the successful bonding of these posts. Commonly used solutions for cleaning and disinfecting the root canals adversely affect the bond strength (BS). Photodynamic therapy is an alternative method for irrigating the root canal and disinfecting the post space.This study was designed to evaluate the impact of photodynamic therapy on the BS of fiber posts to root canal dentin.
