摘要
目的评价牙本质保护膜在全瓷冠修复的活髓牙备牙后牙本质面的保护作用。方法选择63例行全瓷冠修复的患者，共82颗活髓牙，按就诊顺序随机分为A组和B组。A组32例（42颗牙），备牙后涂布牙本质保护膜；B组31例（40颗牙），备牙后涂布Gluma脱敏剂。采用可视分级评价法（VAS）评价探针刺激以及空气刺激预备牙的敏感程度。结果A组：治疗前、后探针刺激以及空气刺激VAS值比较差异有统计学意义（P〈0．05）。B组：治疗前、后探针刺激以及空气刺激VAS值比较差异有统计学意义（P〈0．05）。A组和B组问，探针刺激以及空气刺激VAS值比较差异无统计学意义（P〉0．05）。结论牙本质保护膜能显著降低全瓷冠修复的活髓牙牙体预备后的牙本质敏感症状。
Objective To evaluate the protective effect of dental adhesive resin cement on dentin surface after preparation for all-ceramic crown. Methods 63 patients with 82 teeth prepared for all-ceramic crown were divided into groups A and B in time sequence. Group A （ 32 patients, 42 teeth ）was applied with dental adhesive resin cement; and group B （ 31 patients, 40 teeth ） was applied with Gluma desensitizer. Visual analog scale （ VAS ）was used to assess the sensitivity degree of the prepared teeth using tactile test and air blast test. The results were analyzed using a statistics software. Results In groups A and B, significant differences were found between the baseline VAS value of tactile test and air blast test （ pre-treatment ） and the value gained after both tests （ P〈 0.05 ）. No significant difference was found between group A and group B in the VAS value （ P〉 0.05 ）. Conclusions Dental adhesive resin cement can markedly relieve the symptoms of dentin hypersensitivity after dental preparation of all-ceramic crown.
