Clinical application of glass fiber post in the restoration of endodontically treated teeth

Objective: To evaluate the clinical use of glass fiber post in the restoration of endodontically treated teeth. Methods: Ninety-five patients with 198 endodontically treated incisors were selected and restored with glass fiber post and porcelain-fused-to-metal crown, which age ranged from 20 to 61.The restorations were evaluated clinically according to the modified United State Public Health Service criteria(USPHS) after 15-39 months intervals. Results: During 15-39 months clinical observation, good results were found in aspects of the retention, marginal adaption and recurrent caries. Conclusion: Glass fiber posts could achieve good clinical performance without root fractures. However, more long-term studies with larger numbers of restorations are needed.
