文题释义：
Ceram Xduo纳米树脂：Ceram Xduo是一种双组半透明系列的光固化修复材料，射线不能透过，包括4种近似天然牙本质的半透明材料和3种近似天然牙釉质的颜色，这些颜色相互组合后可涵盖所有的Vitapan标准颜色，可取得较满意的美容修复效果。
铸造金属桩核：具有良好的机械性能、与牙体组织密合性好、修复成功率高、铸造流程简易等优点，常成为后牙桩核系统修复首选，铸造金属桩核所用材料为合金，主要分为贵金属(金合金、钯银合金)和非贵金属(钴铬合金、铜合金等)，贵金属材料弹性模量相对较小，可减少根折风险，但价格昂贵；非贵金属弹性模量高、强度高，应用时要求牙体剩余组织量较多。
 
 
背景：目前临床多使用玻璃纤维桩或金属桩核修复牙体损伤，2种治疗方法均可取得理想的修复效果。
目的：对比金属桩和玻璃纤维桩核修复牙体损伤的效果。
方法：选择湖北职业技术学院附属惠济医院收治的牙体损伤患者112例，其中男52例，女60例，年龄27-74岁，将单号入院者划为对照组(n=56)，采用金属桩核进行修复；将双号入院者划为观察组(n=56)，采用玻璃纤维桩进行牙体修复。记录治疗期间两组不良反应发生情况，包括牙龈炎、桩核折断、全冠松动、牙龈着色、桩核松动等；治疗完成后1周，对比两组修复总有效率；随访3年后，观察修复体边缘适合性、修复完整性及颜色匹配度等；随访3年后，检测两组牙周碱性磷酸酶水平。试验通过湖北职业技术学院附属惠济医院伦理委员会批准，批准号：20150810321。
结果与结论：①对照组牙龈炎、桩核折断、全冠松动、牙龈着色、冠折或根折及庄核松动的发生率明显高于观察组(对照组：8.9%，5.3%，7.1%，5.3%，7.1%，8.9%；观察组：3.5%，1.7%，3.5%，1.7%，3.5%，1.7%，P < 0.05)；②对照组牙体修复总有效率低于观察组(39.29%，85.7%，P < 0.05)；③观察组的修复完整性及颜色匹配度均优于对照组(对照组：80.3%，78.5%；观察组：98.2%，94.6%，P < 0.05)；两组修复体边缘适合性比较无差异(P > 0.05)；④对照组修复后的碱性磷酸水平高于修复前(P < 0.05)，观察组修复前后的碱性磷酸酶水平无变化(P > 0.05)，观察组修复后的碱性磷酸酶水平低于对照组(P < 0.05)；⑤结果表明，应用玻璃纤维桩修复牙体损伤的整体效果明显优于金属桩核。

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
