Abstract:

BACKGROUND: Post-core-crown can maintain the dental tissue to the utmost, restore tooth function and beautify the appearance. Post and core material selection is the key to successful tooth repair.

OBJECTIVE: To compare the application value of fiber post and metal post in repairing the maxillary premolars.
METHODS: Totally 132 patients with maxillary premolar defects (146 teeth) were enrolled, including 54 males and 78 females, aged 43-67 years. According to patient’s willingness, the patients were divided into testing group (fiber post, n=74) and control group (metal post, n=58). All the patients were followed up for 12 months for clinical evaluation. Levels of interleukin-6, interleukin-8, and tumor necrosis factor α in the gingival crevicular fluid were detected before, at 1 week, 1 month, and 12 months after treatment.
RESULTS AND CONCLUSION: Of the 83 affected teeth in the testing group, crown fracture occurred in 2 teeth, post loosening occurred in 2 teeth, and the successful rate was 96.4%. Of the 63 affected teeth in the control group, crown fracture occurred in 1 tooth, root fracture in 4 teeth, post shedding in 3 teeth, periapical change in  2 teeth, and the successful rate was 81.0%. Compared with the control group, the successful rate was higher in the testing group (P < 0.05). After treatment, the levels of interleukin-6, interleukin-8, and tumor necrosis factor α in the gingival crevicular fluid were all significantly decreased in both two group (P < 0.05), but these levels were significantly lower in the testing group than the control group after treatment (P < 0.05). Overall, the fiber post for repairing maxillary premolars can alleviate inflammatory response and improve the treatment success rate, which has a higher application value than metal post.
