Abstract:

Objective: To compare the effects of three kinds of fiber posts (CAD/CAM one-piece glass fiber posts-and-cores, prefabricated glass fiber post and light curing plastic fiber post) on the bond strength of flared root canals and the effect of thermal cycling on their bond strength.Methods: Extracted human single teeth (n=90) were endodontically treated and randomly divided into three groups (n = 30 each). The teeth were restored by three kinds of fiber post: CAD/CAM one-piece glass fiber posts-and-cores, prefabricated posts and light curing plastic fiber post. Following post cementation, the specimens were stored in distilled water at 37 ℃ for 7 days. Half bonded specimens of each group were submitted to thermal cycling (6 000 times, 5 to 55 ℃) prior to micro-push-out bond strength test. Fabrication of micro-push-out bond strength test specimens was conducted by precision slicing machine. The micro-push-out bond strength was tested using a universal testing machine, and the failure modes were examined with a stereomicroscope.Results: In CAD/CAM one-piece glass fiber posts-and-cores group, the bond strength of cervical, middle and apical was (9.58±2.67) MPa,(8.62±2.62) MPa,(8.21±2.48) MPa respectively before thermal cycling, and after thermal cycling the bond strength of cervical, middle and apical was (8.14±3.19) MPa,(6.43±2.47) MPa,(6.45±3.20) MPa respectively. In prefabricated posts group, the bonding strength of cervical, middle and apical was (3.89±2.04) MPa,(4.83±1.23) MPa,(4.67±1.86) MPa respectively before thermal cycling, and after thermal cycling the bond strength of cervical, middle and apical was (6.18±1.61) MPa,(5.15±1.94) MPa,(6.39±2.87) MPa respectively. In light curing plastic fiber post group, the bond strength of cervical, middle and apical before thermal cycling was (4.05±2.41) MPa,(1.75±1.70) MPa,(2.60±2.34) MPa respectively, and after thermal cycling the bond strength of cervical, middle and apical was (5.04±2.72) MPa,(1.96±1.70) MPa,(1.34±0.92) MPa respectively. Postal types and root canal regions were found to significantly affect the push-out bond strength. Compared with the other two groups, the one-piece glass fiber posts-and-cores had the highest bonding strength in the cervical, middle and apical. Temperature cycling has no significant effect on the micro push-out bond strength of three kinds of fiber posts.Conclusion: One-piece glass fiber posts-and-cores has better bonding strength and excellent bonding performance.
