Abstract

BACKGROUND:

More and more structurally compromised teeth are restored with either tapered or parallel-sided glass fiber reinforced posts. While the clinical effect on the restoration with different-shape posts still need to be confirmed.

OBJECTIVE:

To investigate the clinical effectiveness over 2 years of parallel-sided and of tapered glass-fiber posts to restore structurally compromised teeth.

METHODS:

The study population was composed of 121 patients with 156 endodontically treated teeth. They were divided into two groups randomly and restored by the post-and-core technique with either tapered or parallel-sided glass-fiber posts. The final full crowns were either all-ceramic or porcelain-fused-to-metal crowns. The restorations were examined clinically and radiologically every half year. The inspection items included the retention and sealing property of restorations, state of periodontaltissue and occlusal function. The total observation period was 2 years.

RESULTS AND CONCLUSION:

All the patients completed the 2-year clinical investigation. One parallel post was broken at cervical level. In the taper post group, one post was broken and one restoration fall off. The survival rate for parallel-sided posts was 98.7% and for tapered posts was 97.5%. There was no significant difference between these two groups (P > 0.05). It indicated that both parallel-sided posts and tapered posts could achieve satisfactory clinical performance in 2-year follow-up, while long-term effects still need to be observed.
