Desensitizer Oravive 联合 Er：YAG 激光治疗牙本质敏感的疗效观察

摘要

Objective:To observe the clinical effect of Desensitizer Oravive combined Er:YAG laser irradiation on dentin hypersen-sitivity.Methods:240 molars in 86 patients with dentin hypersensitivity were divided into 2 groups(n =1 20).In control group De-sensitizer Oravive was applied to the teeth surface for 30 s;in combination group the teeth surfaces were treated by Er:YAG laser irra-diation for 60 s,and then by Desensitizer oravive for 30 s.Each tooth was treated only once.Pain and pain relief were evaluated by VAS before treatment and immediately,4,8 and 1 2 weeks after treatment.Data were statistically analyzed.Results:Before treat-ment,VAS showed no significant difference between the groups(P >0.05).Both groups exhibited lower VAS after treatment(P <0. 05),VAS values were lower(P <0.05)and the effective rate was higher in the combination group than those in the control group at each treatment stage(P <0.05).Conclusion:Desensitizer Oravive combined with Er:YAG laser is more effective than Desensitizer Oravive in the treatment of dentin hypersensitivity.%目的：观察 Desensitizer Oravive 联合 Er：YAG 治疗牙本质敏感的临床疗效。方法：纳入(牙合)面磨耗造成上颌或下颌第一或第二磨牙牙本质敏感患者86例、240颗牙，随机分为2组（n ＝120）。联合组：Er：YAG 激光照射牙(牙合)面60 s 后再用 De-sensitizer Oravive 涂抹牙(牙合)面30 s；对照组：Desensitizer Oravive 涂抹牙面30 s。每牙均治疗1次。分别观察2组术后即刻、术后4、8、12周 VAS 值和牙本质敏感缓解程度并进行比较。结果：治疗前2组 VAS 基线值差异无统计学意义（P ＞0．05）。与治疗前比较，2组治疗后即刻、4周、12周 VAS 值均有下降（P ＜0．05），联合组下降更为明显（P ＜0．05）；治疗各阶段，联合组治疗有效率均高于对照组（P ＜0．05）。结论：Desensitizer Oravive 联合 Er：YAG 激光治疗牙本质敏感有较好疗效。
