摘　　要：目的分析可塑纤维桩在前牙残根残冠修复中的应用效果。方法根据采用的不同修复桩核,将120例上颌前牙残根残冠患者分为可塑纤维桩者(A组)68例、金属铸造桩者(B组)52例。修复前及修复完成后1周、1个月、1年,分别检测两组患者龈沟液中白介素-6(IL-6)、白介素-8(IL-8)及肿瘤坏死因子α(TNF-α)水平,修复1年后评价总体临床疗效,并比较患者修复失败的因素。结果两组修复后1周、1个月、1年IL-6、IL-8及TNF-α水平均较修复前显著下降,且A组下降幅度显著大于B组;A组1年后修复成功率显著高于B组,而牙龈变色、牙龈红肿、桩冠松动或脱落及牙根断裂的发生率显著低于B组,差异均有统计学意义。结论可塑纤维桩在前牙残根残冠的修复中具有较高的应用价值,可明显减轻炎性反应,有效提高修复成功率。Objective To analyze the application value of EverStick fiber post in the restoration for residual root and crown of upper anterior tooth. Methods One hundred and twenty patients with residual root and crown of upper anterior tooth in our hospital were selected. The patients were divided into group A（EverStick fiber post）68 cases and group B（metal casting post）52 cases according to their will. The levels of interlukin-6（IL-6）,IL-8 and tumor necrosis factor-α（TNF-α）in gingival crevicular fluid before restoration, 1 week, 1 month and 1 year after restoration were detected in both groups,and the total clinical effects and failure factors 1 year after restoration were compared. Results Before restoration, 1 week, 1 month and i year after restoration, the levels of IL-6, IL-8 and TNF-α decreased obviously in two groups, and the decreased range in group A was larger than in group B. The restoration success rate was markedly higher, while incidences of gingival discoloration and swelling, post crown loose or falling off and root fracture were notably lower in group A than in group B after 1 year, with significant differences. Conelusion EverStick fiber post in the restoration for residual root and crown has a higher application value,which can not only alleviate inflammatory response obviously, but also improve the restoration success rate effectively.
