目的评价应用G-BOND自酸蚀黏结系统和全酸蚀黏结系统对楔状缺损修复后牙本质敏感的影响。方法选择2008年6月至2010年12月在大连大学附属中山医院口腔科就诊的牙颈部楔状缺损患者64例,共200颗患牙,自身随机配对分为两组,各100颗患牙。自酸蚀组使用G-BOND自酸蚀黏结系统,全酸蚀组使用全酸蚀黏结系统,进行光固化复合树脂修复,比较两组修复后即刻、1个月、3个月的牙本质敏感改善效果。结果自酸蚀组修复后的牙本质敏感减轻效果明显优于全酸蚀组,组间差异有统计学意义(P<0.05)。结论应用G-BOND自酸蚀黏结系统可降低楔状缺损术后敏感发生。
Objective To evaluate the effect of G-BOND self-etching adhesive system and all-acid-erosion adhesive system on dentin sensitivity after wedge-shaped defect repair. Methods From June 2008 to December 2010, 64 patients with dental wedge-shaped defect in Zhongshan Department of Stomatology, Zhongshan Hospital of Dalian University were enrolled. A total of 200 teeth were randomly divided into two groups with 100 teeth each. Self-etching system using G-BOND self-etching bonding system, all etching group using all-acid etching bonding system, light-cured composite resin repair, two groups were compared immediately after repair, 1 month, 3 months of dentin sensitivity Improve the effect. Results The dentin sensitization effect after self-etching group was significantly better than that of all-acid etching group. The difference between the two groups was statistically significant (P <0.05). Conclusion The application of G-BOND self-etching adhesive system can reduce the incidence of postoperative wedge-shaped defects.
