    International Endodontic Journal, 2015
    Co-Authors: Cecilia Goracci, Jelena Juloski, R. Schiavetti, P. Mainieri, A. Giovannetti, Alessandro Vichi, Marco Ferrari
    Abstract:

    Aim To verify whether the Filler Load of luting agents influences the radiopacity of intraradicularly placed posts. Methodology Digital radiographs of the following posts were taken: RelyX Fiber Post (3M ESPE), GC Fiber Post (GC Corporation), DT Light Post Illusion (RTD), DT Light SL Post (RTD), Endo-Composipost (RTD), FibreKleer Parallel Post (Jeneric Pentron Incorporated), FRC Postec (Ivoclar Vivadent), Parapost Taper Lux (Coltene/Whaledent AG), Radix Fiber Post (Dentsply Maillefer), EverStick Post (Stick Tech Ltd), Dentin Post X (Komet), Tech 21 X-op (Isasan), ENA Post (Micerium). Post radiopacity was measured in millimetres of aluminium (mmAl) with reference to an aluminium step wedge. Two extracted contralateral premolars were root filled. After post space preparation, taking the midpoint of the post hole as a reference, each tooth was cut longitudinally into two halves in a mesiodistal direction. On each half, the exposed root dentine was ground flat to the deepest point of the post space, and an even layer of cement was placed and light-cured. To obtain a clinically relevant layer of cement, the material thickness was reduced to 75 μm by grinding with wet abrasive paper. A cement formulation with 30 wt% of Filler was tested in one premolar, whilst a formulation with 70 wt% of Filler was utilized in the contralateral tooth. Posts were then placed between the two facing root halves of each premolar, and radiopacity was measured in mmAl. Data were analysed using t-test for paired samples (P < 0.05). Results Radiopacity of posts ranged between 1.44 (ENA Post) and 5.78 mmAl (FibreKleer). In the presence of the more heavily filled cement, significantly higher values of post radiopacity were measured (P < 0.001). Conclusion The radiopacity of the luting agent contributed to the overall post radiovisibility within the root. Even when the cement with lower Filler content was used in combination with the least radiodense dowels, the post was detectable within the root.

  • effect of Filler Load on the curing behavior and mechanical and thermal performance of wood flour filled thermoset composites
    Journal of Cleaner Production, 2017
    Co-Authors: Omid Nabinejad, D Sujan, Muhammad Ekhlasur Rahman, Ian J Davies
    Abstract:

    Abstract The mechanical and thermal performance of wood flour composites (WFCs) containing thermoset resin is known to be strongly dependent on the curing reaction. In the present work, WFCs were prepared based on either unsaturated polyester, vinylester or epoxy reinforced by oil palm shell (OPS) flour with a major focus being the preferential reaction of the curing initiator with the natural fiber cells instead of the thermoset resin. Increasing the Loading of OPS was found to delay the curing reaction of all thermoset resins by decreasing the peak exothermic temperature and increasing the time to peak. Selecting a suitable surface treatment for the OPS was observed to play a significant effect on the rate of curing reaction. Thermal degradation (in an inert atmosphere) and linear shrinkage of the WFCs was found to decrease with an increase in Filler Load. In terms of the mechanical performance, the flexural modulus increased steadily with Filler Load whereas the tensile modulus reached its maximum value of 2.74 GPa (30% improvement) at a Filler content of 23 wt% for the hot alkali treated OPS reinforced polyester composite. Increasing the Filler Load was found to decrease the tensile strength whilst the flexural strength experienced an optimal value of 70.6 MPa (28% improvement) for a Filler Load of 9 wt%. Furthermore, the OPS Filler exhibited improved interfacial bonding with the polyester matrix when compared to vinylester and epoxy.
