Abstract Objective: To explore the long-term and long-term effects of traditional metal piles and glass fiber piles in the repair of oral roots. Methods: 94 patients with oral residual root disease admitted to our hospital from January 2016 to July 2018 were enrolled. The patients were divided into two groups according to the random number table method, 47 cases each. The study group (58 teeth) used glass fiber piles for residual root repair, while the control group (56 teeth) used metal piles.The effects of the mid-term (12 months after repair), long-term (24 months after repair) and the health index of the teeth at different times [sulcular bleeding index (SBI), gingival index (GI) ] were compared. Results: At 12 months after repair, the aesthetic effect, prosthetic strength, comfort, and chewing function scores of the study group were higher than those of the control group (P<0.05). The alkaline phosphatase (AKP) level in the control group was significantly higher than that before the repair. High (P<0.05), and there was no significant difference in the AKP level between the study group and the pre-repair (P>0.05).24 months after the repair, the repair effect of the study group (completed restoration, color matching, edge fit) was better than the control group, and the success rate of repair (94.83%) was higher than that of the control group (78.57%). The difference was statistically significant (P <0.05). The incidence of post-core fracture, root fracture, gingivitis, nucleus detachment or loosening, and gingival margin staining in the study group were lower than those in the control group (P<0.05).Repeated measures analysis of variance showed that the interactions between GI and SBI at the time point and group were significant (P<0.05). At 12 months and 24 months after repair, the GI and SBI of the study group were significantly lower. In the control group, the difference was statistically significant (P<0.05). Conclusion: Traditional metal piles and glass fiber piles have certain effects on the repair of oral roots. However, the long-term repair effect of glass fiber piles is better than that of traditional metal piles, which is more conducive to improving the periodontal health index and improving the success rate of repair.
