Purpose: The present study investigated the effect of cement application techniques on the push out test of one type of fiber post (EasyPost) at different root regions cemented with 2 self adhesive resin cements (SmartCem2) and (RelyX Unicem). Materials and methods: A total of 30 single rooted teeth were decoronated 1mm above the cement-enamel junction. Conventional root canal preparation and obturation were performed. The fiber posts were divided into 2 equal groups (n=15 each) according to the self adhesive cement. Group (I): Smart Cem 2. Group (II): Rely X unicem. Each group was further divided in to 3 subgroups (n=5each) according to the method of cement application. Subgroup (i): using A lentuloSpiral. Subgroup (ii): using the application tip. Subgroup (iii): (Control) The cement was applied onto the surface of the posts and into the orifice of the root canal using a small spatula. After cementation all specimens were stored in normal saline then thermocycled. A universal testing machine was used for push-out testing. Data were statistically analyzed using one way ANOVA. A scanning electron microscopic examination was carried out. Results: Regardless to application method or root region it was found that Rely-X cement recorded higher push out bond strength mean value (5.9 ± 2.4 MPa) than Smart-cem2 (4.4 ± 1.4 MPa) (p < 0.05). Conclusions: The technique of application of the self adhesive cements had a great effect on the bond strength of adhesively luted fiber post to root dentine. RelyX Unicem with its elongation tip is considered the most appropriate method as a technique of application. Inadequate adhesion was obtained when SmartCem2 was applied with the application tip method.
