目的探讨玻璃纤维桩在修复前牙残根残冠中的应用效果。方法将2013年1月—2015年12月诊治的120例前牙残根残冠患者随机分为观察组60例(95颗患牙)与对照组60例(97颗患牙),观察组接受玻璃纤维桩修复治疗,对照组接受铸造金属桩修复治疗,计数资料采用χ~2检验,以P<0.05为差异有统计学意义。结果观察组显效66颗、有效26颗、无效3颗;对照组显效52颗、有效27颗、无效16颗;观察组患牙修复效果显著优于对照组,差异有统计学意义(χ~2=2.5557,P<0.05)。观察组非常满意35例、满意23例、不满意2例;对照组非常满意27例、满意21例、不满意12例;观察组治疗满意度显著优于对照组,差异有统计学意义(χ~2=2.0774,P<0.05)。观察组牙根断裂、全冠松动或脱落发生率均低于对照组,差异均有统计学意义(χ~2=7.288、5.209,均P<0.05)。结论玻璃纤维桩修复前牙残根残冠的疗效良好,具有修复成功率及患者满意率高等优点。
Objective To investigate the application effect of glass fiber posts in repairing anterior teeth residual root crown. Methods A total of 120 patients with residual anterior residual root crown who were diagnosed and treated from January 2013 to December 2015 were randomly divided into 60 cases (95 teeth) in the observation group and 60 cases (97 teeth) in the control group. The observation group received Glass fiber post repair treatment, the control group received casting metal post repair treatment, count data usingχ ~ 2 test to P <0.05 was considered statistically significant. Results The observation group showed 66 effective, 26 effective, 3 ineffective; the control group markedly effective 52, effective 27, ineffective 16; the healing effect of the observation group was significantly better than the control group, the difference was statistically significant (χ ~ 2 = 2.5557, P <0.05). The observation group was very satisfied with 35 cases, satisfied with 23 cases, not satisfied with 2 cases; the control group was very satisfied with 27 cases, satisfied with 21 cases, not satisfied with 12 cases; the observation group treatment satisfaction was significantly better than the control group, the difference was statistically significant (χ ~ 2 = 2.0774, P <0.05). In the observation group, the incidence of tooth root fracture and total crown loosening or shedding were all lower than those in the control group (χ ~ 2 = 7.288,5.209, all P <0.05). Conclusion Glass fiber post repair residual crown of the anterior teeth with good curative effect, with the success rate of repair and patients with high rate of satisfaction.
