Abstract：BACKGROUND:Post-core restoration of dental defects can restore the morphology and function of the teeth. Glass fiber post and casting metal post are commonly used in the post-core restoration, and have different repair effects. OBJECTIVE:To compare the effect of glass fiber post and metal post restoration for dental defects. METHODS:97 patients of dental defects in 146 teeth were divided into two groups, glass fiber post group (49 cases, 74 teeth) and casting metal post group (48 cases, 72 teeth). Al patients were folowed up for 12 months. Periodontal alkaline phosphatase levels, integrity of dental prosthetics, edge matching condition, color matching condition, crown post rupture, prosthetic loosening and dental root rupture were observed before repair and 24 hours after repair. RESULTS AND CONCLUSION:At 24 months after repair, alkaline phosphatase levels in the casting metal post group were significantly increased compared with before repair (P< 0.05), and were obviously higher than that in the glass fiber post group (P< 0.05), there was no significant differen ce in the glass fiber post group before andafter repair (P > 0.05). The edge matching condition and color matching condition in the glass fiber post group were significantly better than that in the casting metal post group (P< 0.05). Six teeth in the glass fiber post group and 17 teeth in the casting metal post group appeared crown post rupture, and the successful repair rate in the glass fiber post group was significantly higher than that in the casting metal post group (91.9%, 76.4%,P< 0.05). Compared with casting metal post, glass fiber post can restore better appearance, better mechanical functions, higher success rate and fewer impact on periodontal tissue.
