摘要:
目的 采用临床随机对照的方法 观察和评估玻璃纤维牙本质桩结合纳米树脂直接法修复上中切牙切角缺损后的的临床效果。方法 选取2013年6月至2016年2月解放军第一一七医院口腔科门诊收治中切牙切角缺损患者94例，共132颗患牙。将所有患者按数字随机表分为对照组、观察组各47例。观察组68颗患牙采用玻璃纤维牙本质桩加纳米树脂直接法充填修复，对照组64颗患牙仅采用纳米树脂直接充填，比较治疗后 7d、６个月和２年2组修复体边缘适合性、充填体脱落和边缘染色等3项指标的失败率。结果 治疗7d后，2组的修复体边缘适合性、充填体脱落和边缘染色均未出现异常；观察组治疗6个月后3项观察指标失败率低于对照组，但差异均无统计学意义（P>0.05）；观察组2年后较对照组修复体边缘适合性（2.9% vs 12.5%）和边缘染色（4.4% vs 20.3%）失败率明显降低（P<0.05）。结论 玻璃纤维牙本质桩能够增强纳米树脂修复上中切牙切角缺损的远期效果。
Abstract:
Objective This research aims to observe the clinical effect of glass fiber dentin post with composite resin restoration on incisal angle defects.Methods A total of 94 patients with incisal angle defects were selected from June 2013 to February 2016 in the 117th Hospital of PLA. All patients were randomly divided into control group and experimental group. The experimental group (68 teeth) were restored with glass fiber post and composite resin. The control group (64 teeth) were restored with composite resin only. The scores of marginal adaptation, restoration retention, and marginal discoloration were evaluated and recorded at 7 days, 6 months and 2 years after treatment.Results Both experimental group and the control group were not abnormal after 7 days of treatment. The failure cases of experimental group after 6 months of treatment of three observation index were lower than that in the control group, but there were no significant differences between the two groups（P>0.05）. The failure cases of experimental group after 6 months of treatment of three observation index were lower than that in the control group, but the restoration retention of two groups were shown non-significant difference. The marginal adaptation（2.9% vs 12.5%） and marginal discoloration （4.4% vs 20.3%） between the two groups were statistically significant difference（P<0.05）.Conclusion The glass fiber dentin post could effectively enhance the long-term effect of composite resin on treatment of incisal angle defects.
