摘要
目的评价牙本质即刻封闭技术对瓷贴面修复后基牙敏感的防治效果。方法选择76名患者的138颗活髓前牙进行瓷贴面基牙预备后随机分为试验组和对照组。其中,试验组69颗牙齿,基牙预备后,用牙本质粘接剂(single bondⅡ)涂布于基牙表面再取印模;对照组69颗牙齿,基牙预备后直接取模。然后2组均常规制作临时冠粘接。在取模后24 h、1周和1个月时去除临时冠,对预备的基牙唇面进行敏感程度的评估后,做瓷贴面粘接。结果基牙预备后其敏感程度24 h评估与1周后评估,试验组与对照组比较均在1度和2度上差异有统计学意义;而1个月后进行评估,试验组与对照组牙齿敏感程度在0度和2度上差异有统计学意义。结论瓷贴面基牙预备之后,在取模之前运用牙本质粘接剂可以降低基牙的敏感程度,减少患者适应义齿的时间。
Objective To evaluate the effect of immediate dentin sealing in the prevention of dentin hypersensitivity after porcelain veneer restoration.Methods 76 patients with 138 upper anterior teeth in different patients were randomly divided into two groups,namely experiment group(69 teeth) of dentin bonding agent(single bond Ⅱ) coating the preparational surface of abutment and light-cured following preparation before making the impression,control group(69 teeth) of making the impression after preparation directly.After the removal of the temporary veneer,sensitive evaluation of labial surface of abutment 24 hours,one week later,and one month later before the veneer restoration finished was conducted.Results There are significant differences between experiment group and control group in 1 degree and in 2 degrees when evaluated prepared 24 hours and one week later.There is significant difference between experiment group and control group in 0 degree and 2 degrees when evaluated prepared one month later.Conclusion The effect of dentin bonding agent in the prevention of dentin hypersensitivity after porcelain veneer restoration are significant.In our clinical trail,coating the preparational surface of abutment and light-cured following preparation before making the impression can reduce the abutment hypersensitivity and shorten the time of patients who adapt to the dentures.
