摘要
目的探讨自酸蚀黏接剂对树脂充填体边缘封闭后微渗漏的影响。方法选取2015年2月~2016年3月我院60颗新鲜离体双尖牙,将制备好的新鲜离体双尖牙按照不同黏接剂分为观察组和对照组,各有30颗新鲜离体双尖牙。观察组采用自酸蚀黏接剂,对照组采用纳米全酸蚀黏接剂,比较两组树脂充填体边缘封闭后微渗漏情况、牙齿窝洞深度。结果观察组染料渗入牙齿窝洞深度为(0.45±0.12)mm,对照组为(1.16±0.24)mm,差异有统计学意义(P<0.05)。观察组树脂充填体边缘封闭后微渗漏情况显著优于对照组,差异有统计学意义(P<0.05)。结论自酸蚀黏接剂具有操作简单、效果良好的优点,能有效降低染料渗入牙齿窝洞深度,改善微渗漏等级,为树脂充填体边缘封闭后微渗漏的首选治疗方式,值得临床进一步推广应用。
Objective To investigate the effect of self-etching adhesive on microleakage after sealing of resin-filled body.Methods Sixty fresh bicuspid in vitro in our hospital from February 2015 to March 2016 were collected and divided into two groups according to the different adhesive,30 teeth in each group.The observation group was treated with self-etching adhesive,while the control group was given nano-full-etching adhesive,microleakage after sealing resin-filled body and tooth cavity depth between two groups were compared.Results There was significant difference（P〈0.05）in the depth of dye penetration into the tooth cavity [（0.45±0.12） mm] in the observation group and that in the control group [（1.16±0.24） mm].The edge of the resin filling post-microleakage in the observation group was significantly better than that in the control group,and the difference was statistically significant（P〈0.05）.Conclusion Self-etching adhesive has the advantages of simple operation and good effect.It can effectively reduce the penetration depth of dyed tooth and improve the microleakage grade.It is the first choice of microleakage after resin sealing,worthy of further promotion and application.
