| Research Abstract |
(1)The fracture strength of structurally compromised tooth with flared root canal was high value when the cast metal post and core was cemented after the reinforcement of the tooth structure used resin composite together with the clear acrylic post.
(2)Composite resin cores with the experimental posts without glass fiber have similar fracture strength to that with prefabricated glass fiber posts and the fracture strength of endodontically treated teeth restored with composite resin cores is not influenced by the flexural modulus of these posts.
