| dc.description.abstract | Aim: The aim of the study was to assess and determine the fatigue resistance of different fiber
posts and to observe their ultrastructures through scanning electron microscopy (SEM).
Objectives: To assess and compare the fatigue resistance of 4 different types of fiber posts, to
analyse and compare the surface morphology using scanning electron microscopy (SEM) and
to determine a correlation between the fatigue resistance exhibited by the different types of
posts and their structural characteristics. Materials and Methods: Four types of aesthetic posts
were selected for this study, namely: Radix Fiber Post (Dentsply Sirona, USA, zirconia glass
fiber), ParaPost Fiber White (Coltene/Whaledent, NJ, USA, glass fiber), Edelweiss Composite
Posts (Edelweiss Dentistry, Austria, hybrid glass) and GC Fiber Post (GC, Tokyo, Japan, glass
fiber). For each group, the 15 largest posts available were used. For the fatigue testing 10 posts
were used, the remaining 5 were used for processing in SEM evaluation. | en_US |
