Objective: The aim of this study was to assess the micro-push-out bond strength a mineral-based root canal sealer, BioRoot RCS in canals prepared by K3XF rotary systems two different tapers. Material and Methods: Eighty caries free maxillary central incisors were used study. samples allocated into 4 groups (n=20) according sealer taper instruments. obturated using single cone obturation techniq...

This study evaluated the influence of the cementation system on the regional push-out bond strength and failure pattern of fiber posts to radicular dentin. The roots of 48 extracted human incisors were prepared and divided into 3 groups (n = 16), according to the cementation system: AdperScotchbond Multi-Purpose + resin cement RelyX ARC (SBMP+ARC); Adper SingleBond 2 + RelyX ARC (SB+ARC) and; R...

Introduction: An apical sealing material may be exposed to an inflamed environment with low pH levels. The change in physical and chemical properties of mineral trioxide aggregate has been well-documented in the presence of low pH. However, on literature search there is no documentation of the effect of low pH on BiodentineTM. Aim: To compare the effects of various levels of acidic pH on the pu...

Aims The aim of the study was to evaluate the effect of 10% sodium ascorbate (SA),10% hesperidin, 1% riboflavin 5-phosphate, collagen cross-linkers, on the pushout bond strength of the fiber resin postluted to the radicular dentin. Materials and Methods Twenty-eight, single-rooted extracted human teeth were collected. The cleaning shaping and obturation was done followed postspace preparation...

INTRODUCTION The aim of this in vitro study was to evaluate the effect of 2% chlorhexidine (CHX) on the push-out bond strength (BS) of calcium-enriched mixture (CEM) cement. METHODS AND MATERIALS Root-dentin slices from 60 single-rooted human teeth with the lumen diameter of 1.3 mm were used. The samples were randomly divided into 4 groups (n=15), and their lumens were filled with CEM cement ...
