Push-out Bond Strength of Root-end Filling Materials [PDF]

open access: yesBrazilian Dental Journal, 2016
Abstract The aim of this study was to evaluate the bond strength of root-end filling materials. Forty 2-mm-thick slices were obtained from human single-rooted teeth. After root canal preparation using a 1.5 mm diameter cylindrical drill, the dentinal walls were prepared by diamond ultrasonic tip (CVD T0F-2).

The push out bond strength of polydimethylsiloxane endodontic sealers to dentin [PDF]

open access: yesBMC Oral Health, 2019
The purpose of this experiment was to assess the push out bond strength of Polydimethylsiloxane sealers (GuttaFlow 2 and GuttaFlow Bioseal by Colte'ne/Whaledent, Altstätten, Switzerland). AH Plus (Dentsply, DeTrey, Konstanz, Germany) was used as a reference material for comparison.Thirty root slices were prepared from the middle third of 10 mandibular ...

Push-out bond strength of different endodontic obturation material at three different sites : in-vitro study [PDF]

open access: yes, 2017
The key to success of any root canal therapy is adequate obturation of the prepared root canal space. Root canal sealers are not dimensionally stable and might dissolve partially over a period of time.
