Abstract:

BACKGROUND: Glass fiber post or metal post and core are currently used to repair dental injury in the clinic. Both methods can achieve ideal repairing effect. 
OBJECTIVE: To investigate the effect of glass fiber post and metal post and core on repairing dental injuries.
METHODS: 112 patients with dental injury were selected, including 52 males and 60 females, aged 27-74 years. The patients with odd numbers provided at admission were assigned to the control group (n=56) and received dental repair by metal post and core, and those with even numbers were assigned to the observation group (n=56) and received dental repair with glass fiber post. The incidence of adverse reactions during treatment was recorded, including gingivitis, post and core fracture, crown loosening, gingival staining, post and core loosening. The total effective rate was compared between the two groups 1 week after treatment. The marginal fitness, restoration integrity, and color matching of the two groups were observed at 3 years of follow-up. The levels of periodontal alkaline phosphatase were measured at 3 years of follow-up. This study was approved by the Ethics Committee of Huiji Hospital Affiliated to Hubei Vocational and Technical College of China (approval No. 20150810321)
RESULTS AND CONCLUSION: The incidences of gingivitis, post and core fracture, crown loosening, gingival staining, crown or root fracture and post and core loosening in the control group were significantly higher than those in the observation group (control group: 8.9%, 5.3%, 7.1%, 5.3%, 7.1%, 8.9%; observation group: 3.5%, 1.7%, 3.5%, 1.7%, 3.5%, 1.7%, P < 0.05). The total effective rate of dental repair in the control group was significantly lower than that in the observation group (39.29%, 85.7%, P < 0.05). The repair integrity and color matching in the observation group were better than those in the control group (control group: 80.3%, 78.5%; observation group: 98.2%, 94.6%, P < 0.05); and there was no difference in the marginal fitness between the two groups (P > 0.05). In the control group, alkaline phosphatase level was significantly higher after dental repair than that before repair (P < 0.05). In the observation group, alkaline phosphatase level did not change after dental repair compared with before dental repair (P > 0.05). The alkaline phosphatase level in the observation group was significantly lower than that in the control group (P < 0.05). The results suggest that the overall effect of glass fiber post in repairing dental injury was superior to that of metal post and core.

Key words: glass fiber post, metal post and core, dental injury, post and core fracture, full crown loosening, nano resin, alkaline phosphatase, repair
