PD纤维根管桩在残冠修复中的应用 　　[摘要] 目的 探讨PD（produits dentaires）纤维根管桩在??冠修复中的应用。 方法 选取2014年1月～2016年12月我院收治牙体牙髓病变60例作为观察组，给予其残冠修复，跟踪其修复结果，同期另选取50例健康体检者作为对照组，观察组修复前与修复后12个月（修复后）和对照组比较咀嚼功能及牙龈状况。 结果 经为期12个月随访，本组病例中58例获得成功，2例获得失败，成功率为96.66%。其中2例失败，其失败理由均为牙龈充血、水肿。修复前，观察组咬合力、咀嚼效率及牙龈指数均显著低于对照组，差异具有统计学意义（P0.05）。 结论 PD纤维根管桩与牙体具有高度的兼容性，是一种理想的残根残冠桩核修复材料。 　　[关键词] 玻璃纤维根管桩；残根残冠；牙髓病变 　　[中图分类号] R783.5 [文献标识码] A [文章编号] 2095-0616（2017）10-226-03 　　Application of residual crowns repair with PD fibrous root pile 　　LI Jie 　　Department of Dental， Huangpu District Hospital of Traditional Chinese Medicine， Guangdong， Guangzhou 510700， China 　　[Abstract] Objective To discuss the application of residual crowns repair with PD Fibrous root pile. Methods 60 cases of patients with Tooth pulp lesions in our hospital from January 2014 to December 2016 were selected as observation group， and they were treated with residual crown repair， tracking the results of its repair. At the same time， 50 cases of healthy persons were selected as control group. Masticatory function and gingival status before and 12 months after repair of the two groups were compared. Results Through 12 months follow up， there were 58 cases succeeding in observation group， and 2 cases were failed， so the rate of success was 96.66%. The reason of the 2 fail cases was about gum hyperaemia oedema.before the repair， bite force， masticatory efficiency， Gingival index of observation group were significantly lower than those of control group. There were statistical significances （P0.05）. Conclusion PD fibrous root pile is a kind of ideal residual root and crown of pile nuclear restorative materials. It has highly compatibility with teeth. 　　[Key words] Glass-fiber post； Residual root and crown； Pulpal pathosis 　　既往桩核修复主要采用金属桩核作为修复材料，因镍铬合金、银钯合金等桩核材料与牙体特性兼容性稍有欠缺，而时有发生牙龈染色、牙周炎症及牙体组织折裂等不良事件，结果不甚良好[1-2]。随着科学技术的不断提高，口腔修复材料的长足进展，复合树脂高强纤维材料出现于临床医师视野[3]。故我院于2014年1月～2016年12月采用PD纤维根管桩在残冠修复中取得良好效果，现报道如下。 　　1 资料与方法 　　1.1 一般资料 　　选取2014年1月～2016年12月我院收治
