    【Abstract】ObjectiveTo compare the clinical effect of fiber post and metal post for restoration of anterior teeth. Methods fiber post (group A, n 52) and metal post (group B, n50) were applied for restoration of 102 anterior teeth. The effect of restoration was evaluated after a follow-up period of one year. ResultsThe treatment is effective in 50 cases and failed in 2 case of group A. The treatment is effective in 40 cases and failed in 10 cases in group B. The difference between these two groups was statistically significant. Conclusion fiber post core has better clinical effect than metal post core in restoration of anterior teeth. ......
