Abstract The aim of this study was to evaluate the fracture resistance of endodontically treated teeth that were prosthetically restored with two fiber post designs (smooth and serrated) with different lengths (6, 8 and10mm). A total of Thirty intact upper central incisors were collected and decoronated 2mm coronally. Teeth were prepared 2mm ferrule circumferential and chamfer finish line of 0.5 mm. The teeth were embedded in epoxy resin blocks using a centralizing device. Root canals were prepared and obturated then post holes were prepared with the corresponding drill using the drilling machine, In this study the thirty samples were divided into 2 groups (n = 30) according to the post surface design group Ї: parallel smooth glass fiber post. (n = 15). group ЇЇ: parallel serrated glass fiber post. (n = 15) |
