Aim of the study: The purpose of the study was to compare and evaluate clinically and radigraphically three different types of prefabricated posts (glassfiber, carbonfiber coated with fiber glass and metal posts), cemented by two different resin cements in restoration of endodontically treated permanent incisors. Also the aim of this study was to measure the fracture resistance as well as the push out test for the different types of posts and cementation techniques.Materials and Methods: Sixty fractured permanent upper incisors indicated for endodontic treatment and post restoration of children aged between nine and fourteen years with mean age of (12.2 ± 1) have been selected in this study. The selected subjects were divided randomly into three groups according to the post materials, each group was subdivided into two groups according to resin cement used. Subjects were followed for one year both clinically and radiographically immediately postoperatively, 3 months, 6 months and 12 months postoperatively. Also sixty single rooted teeth are sectioned at the cemento-enamel junction and treated endodontically. Post holes will be prepared according to the manufacturer’s instructions using the corresponding burs. Then, specimens are divided into the same experimental groups. Retentive bond strength was measured using push-out test.A compressive load was applied and all samples were loaded until failure (fracture resistance test). Data were collected and statistical analysis.Results: Carbon fiber posts exhibited highest fracture resistance among the three post types and highest retentive values especially when cemented with Multilink resin cement.Conclusion: Carbon fiber posts with Multilink resin cement are the best to be used in restoring root canal treated anterior teeth, regarding fracture and retention strength values.Traumatic Dental Injuries; Prefabricated posts materials;Resin cements.
