Limitations of Push-out Test in Bond Strength Measurement

Journal of Endodontics, 2013
The push-out test has been widely performed to measure the bond strength of intracanal materials in dentistry. However, it is difficult to compare equitably the bond strengths from different testing specimens. The aim of this study was to investigate how a specimen's geometric parameters and the elastic moduli of dentin and intracanal filling materials

Evaluation of push-out bond strength of a new MTA-based sealer

European Archives of Paediatric Dentistry: Official Journal of the European Academy of Paediatric Dentistry, 2013
To evaluate the push-out bond strength of MTA Fillapex (Angelus) and compare it with ProRoot MTA (Dentsply) and AH Plus (Dentsply).Thirty extracted single-rooted teeth were selected and prepared using a rotary system. The samples were divided randomly into three groups (n = 10) and obturated, respectively, with: (1) AH Plus + gutta-percha (DiaDent); (2)

Push-out bond strength of circular and oval-shaped fiber posts

Clinical Oral Investigations, 2010
This study aimed at evaluating the post-root dentin push-out bond strength of circular and oval posts luted in oval-shaped canals with two different resin cements. Twenty extracted premolars with oval-shaped canals were selected, endodontically instrumented and obturated. The teeth were divided into two groups according to the drill used for post-space

Effect of Acidic Environment on the Push-out Bond Strength of Mineral Trioxide Aggregate

Journal of Endodontics, 2010
Reduced surface microhardness and decreased sealing ability have been shown after the placement of mineral trioxide aggregate (MTA) in an acidic environment. In this study, the effect of an acidic environment on the push-out strength of MTA was evaluated.Eighty root dentin slices from freshly extracted single-rooted human teeth were sectioned and their

Push-Out Bond Strength of a New Endodontic Obturation System (Resilon/Epiphany)

Journal of Endodontics, 2007
Endodontic sealers should demonstrate adhesive properties to dentin to reach the objectives of the obturation of the canal space and seal the canal space both apically and coronally, thus decreasing the chance of endodontic treatment failure. Adhesion to dentin with bonding to the tooth structure in the canal may provide greater resistance to tooth ...

Push‐out bond strength of an experimental self‐adhesive resin cement

European Journal of Oral Sciences, 2012
The adhesion of fiber posts luted with simplified adhesive systems has been a matter of great interest over the past years. The aim of this study was to assess the post retentive potential of experimental self‐adhesive resin cement (EXP) when used alone and in combination with a self‐etch adhesive.

Suboptimal push‐out bond strengths of calcium silicate‐based sealers

International Endodontic Journal, 2015
AbstractAimTo evaluate and compare the push‐out bond strength of MTA Fillapex (Angelus, Londrina, Brazil) and iRoot SP (Innovative BioCeramix Inc., Vancouver, Canada) to the dentine walls of root canals. AH Plus (Dentsply DeTrey, Konstaz, Germany) and MTA (Angelus, Londrina, Brazil) were used as reference materials.MethodologySixty extracted human ...

Comparison of Push-out Bond Strengths of Resilon with Three Different Sealers

Journal of Endodontics, 2010
The purpose of this study was to evaluate the push-out bond strengths of different obturating materials.Forty single-rooted human extracted teeth were used in this study. The teeth were instrumented and irrigated by using 5.25% NaOCl, 15% ethylenediaminetetraacetic acid, and sterile water.

Evaluation of Push-out Bond Strength of Two Endodontic Post Systems

Journal of Endodontics, 2012
The aim of this study was to evaluate the push-out bond strengths of a new polyfiber post system and a fiber post that were adhesively luted with a dual-cure resin cement.Forty single-rooted human maxillary teeth were sectioned below the cementoenamel junction, and the roots were endodontically treated.
