Effect of surface treatment and type of cement on push-out bond strength of zirconium oxide posts.

Statement Of Problem: The effect of the surface treatment of zirconium oxide posts on their push-out bond strength is controversial.

Purpose: The purpose of this study was to compare the effects of 2 surface treatments on the bond strength of zirconium oxide posts cemented with different cements and to assess the failure mode.

Material And Methods: Seventy extracted human teeth were divided into 7 groups (n=10).

Effect of types of luting agent on push-out bond strength of zirconium oxide posts.

Objective: The aim of this study was to investigate the effect of different luting agents on the bond strength of zirconium oxide posts in root canals after artificial ageing.

Material And Methods: Thirty single-rooted extracted teeth were collected. Post spaces were prepared.

Bond strengths of custom cast and prefabricated posts luted with two cements.

Objective: This in vitro study evaluated the bond strength of custom cast and prefabricated posts luted with resin or zinc phosphate cements into unobturated canals of extracted teeth.

Method And Materials: Forty-eight custom cast and prefabricated posts were placed into extracted single-rooted human teeth. Post-cavity preparation was 1.
