Nd∶YAP激光联合自酸蚀粘接和树脂修复治疗牙本质敏感的临床研究

摘要

目的 探讨Nd∶YAP激光联合自酸蚀粘接系统对牙本质敏感的临床疗效.方法 选取108颗需要树脂充填的牙本质敏感患牙,随机分为实验组和对照组.实验组使用Nd∶YAP激光处理牙面后,联合自酸蚀粘接系统和树脂充填修复;对照组直接使用自酸蚀粘接系统和树脂充填修复,分别在治疗后6个月和12个月对牙敏感性,充填体固位性,充填体边缘密合性和总体疗效进行评估.结果 治疗后12个月随访,实验组牙齿敏感度改善情况、充填体固位性、充填体边缘密合度均优于对照组,差异有统计学意义(P＜0.05);实验组总体疗效高于对照组,差异有统计学意义(P＜0.05).结论 Nd∶YAP激光联合自酸蚀粘接系统对改善牙本质敏感疗效明显,充填体固位力和边缘密合度优,适合用于需要充填的牙本质敏感患者.%Objective To investigate the clinical effect of Nd∶YAP laser combined with self-etching adhesive system on dentin hypersensitivity.Methods 108 dentin-sensitive teeth requiring resin filling were selected and randomly divided into experimental group and control group.The experimental group were treated with Nd∶ YAP laser combined with self-etching adhesive system and Fushita F00 resin to restore the defect,while the control group were only treated by self-etching system.Tooth sensitivities,filling retention,marginal adherence and overall efficacy of the filling were used to evaluate the treatment effect respectively 6 and 12 months follow up.Results At 12 months after treatment,the improvement of dental sensitivity,the filling retention and marginal adherence of the experiment group were better than the control group (P ＜0.05).The difference of the overall efficacy between two groups was statistically significant (P ＜0.05).Conclusion Nd∶ YAP laser combined with self-etching adhesive system has obvious effect on dentine hypersensitivity.
