Özet

The aim of this in vitro study was to evaluate the adhesion strength of two new fiber post systems (FiberSite (TM) Post and Cytec (TM) Blanco Post) cemented with two different adhesive resin cements (Panavia (TM) SA and Maxcem (TM) Elite). Root canals of sixty extracted human mandibular premolars were prepared using ProTaper Universal (TM) rotary files (Dentsply Sirona Endodontics, York, PA, USA). The root canals were irrigated with 5.25% sodium hypochlorite (NaOCl) during instrumentation. After root canal preparation, the canals were irrigated with 2 mL of 17% EDTA (1 min), followed by 2 mL of 5.25% (5 min) NaOCI, and 2 mL saline. The root canals were dried with paper points and divided randomly into two study groups (n = 30) according to the type of post system: Group 1, FiberSite (TM) Post (MegaDental, Partanna, Italy); and group 2, Cytec (TM) Blanco Post (Hahnenkratt, Konigsbach-Stein, Germany), with one of the two adhesive resin cements: Subgroup A, Panavia (TM) SA Cement Plus Automix (Kuraray, Osaka, Japan); subgroup B, Maxcem (TM) Elite (Kerr, Orange, CA, USA). Following thermocycling, the adhesion strength was evaluated using the push-out adhesion (bond) strength test. Fractographic analysis was performed using stereomicroscope. The data were analyzed using two-way analysis of variance (p = 0.05). The adhesion strength values of both the posts were significantly higher when cemented with subgroup B (Maxcem (TM) Elite). The highest adhesion strength value was demonstrated by group 1B (FiberSite (TM) post cemented with Maxcem (TM) Elite cement). The type of post did not have a significant impact on the bond strength values for either cement material.
