Effect of different irrigant activation protocols on push-out bond strength

Lasers in Medical Science, 2015
The study aimed to evaluate the effect of various final irrigant activation protocols on push-out bond strength of fiber post. Thirty-two single-rooted human maxillar central teeth were sectioned below the cementoenamel junction, instrumented and obturated.

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.

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

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

European Archives 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)

Thermocompaction decreases long-term push-out bond strength of methacrylate-based sealers

Acta Odontologica Scandinavica, 2015
The purpose of this study was to evaluate the immediate and long-term bond strengths to root dentin of Epiphany/Resilon and AH Plus/gutta-percha fillings, after using either lateral condensation or Tagger's hybrid thermomechanical compaction techniques.Eighty human single-rooted teeth were used. The root canals were prepared by means of hand crown-down

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 ...

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.

Push-out bond strengths of tooth-colored posts bonded with different adhesive systems.

American journal of dentistry, 2005
To evaluate the effect of luting systems and root region on the push-out bond strengths of a glass fiber-reinforced post and a zirconia post.Thirty-two extracted human anterior teeth (central incisors and canines) were endodontically treated with lateral condensation of gutta percha and AH26 sealer.
