Abstract:
To compare the microleakage of fiber post and resin-core system fabricated by different methods.The roots of 36 recently extracted single-rooted mandibular premolars were undergone endodontic treatment.Fiber posts and Paracore flowable resin composite were used for fabricating post-core restorations.Microleakage was examined by dye penetration method.The microleakage value was significantly higher in Direct-Mold-Cement-Method group(4.94 ± 1.71) mm compared to Direct-Mold-Secondary-Cement-Method group(0.91 ±0.33) mm and Indirect-Mold-Secondary-Cement-Method group (0.87 ± 0.27) mm (P ＜ 0.05).
