The retentive effects of pre-fabricated posts by luting cements

summary  The purpose of this study was to compare the retention of two different pre‐fabricated posts cemented to the root canal with four different adhesive luting cements and a zinc phosphate cement. The crowns of 100 freshly extracted human mandibular central and lateral incisors were removed at...

Description
Summary:summary  The purpose of this study was to compare the retention of two different pre‐fabricated posts cemented to the root canal with four different adhesive luting cements and a zinc phosphate cement. The crowns of 100 freshly extracted human mandibular central and lateral incisors were removed at the cementoenamel junction and divided into two main groups (A = ParaPost and B = Flexi‐Post) and further divided into five subgroups to evaluate the effects of five different cements (Rely‐X ARC, Panavia F, ParaPost Cement, Flexi‐Flow Natural and Adhesor) each with 10 samples. Post‐holes were prepared on all of the roots following the manufacturer's instructions. Each sample was placed into a specialized jig and tensile strength tests performed by using testing machine with a crosshead speed of 0·638 cm min−1 and force applied until failure. The data were analysed with one‐way anova (Post Hoc a Scheffe's S test) and two‐way anova (P
