Abstract:
BACKGROUND:Studies have shown that fiber post is superior to cast metal post in the restoration of large-area dental defects, in prognostic terms of post and core crown off, post and core breakage, root fracture. OBJECTIVE:To explore the application value of glass fiber post and cast metal post in restoration of tooth defects. METHODS:Totaly 100 patients with dental defects (150 teeth; 51 males and 48 females) were selected and randomly divided into observation group (50 cases, 70 teeth) and control group (50 cases, 80 teeth). Al of the patients were treated with glass fiber post and metal post repair. After repair, al the patients were folowed up for 1-3 years. The repair effect of the two groups were observed and compared in terms of integrity, color matching, marginal fit, periodontal pocket depth, alkaline phosphatase activity and post and core crown damage. RESULTS AND CONCLUSION:After 1 year of repair, the observation group was better than the control group in aspects of marginal fit and color matching (P < 0.05); after 1-3 years, the alkaline phosphatase activity was significantly lower in the observation group than the control group (P < 0.05), and there was no difference in the periodontal probing depth between the two groups; while the observation group exhibited higher successful rate than the control group (P < 0.05). The results show that compared with the cast metal post, glass fiber post is better for restoration of tooth defects, exhibiting better restoration effect and long-term success rate, which is conducive to the maintenance of periodontal health.
