Abstract:

 Background: The purpose of this study was to compare regional bond strength at middle and cervical thirds of theroot canal among glass fiber-reinforced composite (FRC) endodontic posts cemented with different cements, usingthe push-out test to compare the performance (retention) of two types of luting cements; polycarboxylate cementand Zinc phosphate cement used to cement translucent fiber post and to compare the result of the push-out testat different storage times;1 week ,1month and 2 months.Materials and methods: Ninety caries-free, recently extracted single-rooted human teeth with straight root canalswas used in this study, The root canals were endodontically instrumented at a working length of 0.5 mm from theapex by means of conventional instruments for hand use (Dentsply, Switzerland) up to size 35.then root canal fillingwas performed followed by post space preparation up to 8mm including cervical and middle one third of root canalthen the fiber post was cemented into canal post space then the root was sectioned to get cervical (4 mm inlength) and middle (4 mm in length) thirds ,these thirds were examined by push out test to get values of retention offiber post inside these canal thirds .Results and Conclusions: The results of this study has been showed that there was no significant differences betweenpush out bond strength between fiber post and root at cervical third as compared with middle third when usingpolycarboxylate cement or Zinc phosphate cement to cement the fiber post to the canal walls and the resultsshowed that there was no significant differences in push out bond strength for polycarboxylate or Zinc phosphatecement after one and two months but there was highly significantly increase in push out bond strength for resincements used to cement the fiber post to the root canal after one and two months.
