GLUMA CPS脱敏性粘接系统治疗牙本质过敏症的临床研究

目的：试验GLUMA CPS脱敏性粘接系统治疗牙本质过敏症的疗效，并探索其最佳应用方式。方法：将152例361个患牙随机分为4组，3个实验组分别用GLUMA CPS粘接系统中的Primer(牙本质粘接剂）、Conditioner(酸蚀处理剂）＋Primer即C＋P、Conditioner Primer Sealer(封闭剂）即C＋P＋S进行脱敏治疗；对照组用75％氟化钠甘油脱敏，比较各组的有效率，3月后复查。结果：C＋P和C＋P＋S两组有效率显著高于另外两组（P＜0．01），且两组之间无显著差异（P＞0．05），3月后亦然。结论：GLUMA CPS脱敏性粘接系统对牙本质过敏症疗效确切而持久，C＋P为其最佳应用方式。

A clinical study on the effects of GLUMA CPS desensitizing bonding system in the treament of dentin hypersensitivity

AIM:The purpose of this study is to test the curative effects of GLUMA CPS desensitizing bonding system and the best way to be applied in the treatment of dentin hypersensitivity. METHODS: 361 sensitive teeth in 152 patients were devided into four groups randomly. Three experimental groups were treated with primer(dentinal bonding agent), Conditioner(acid etching agent) Primer, and Conditioner Primer Sealer(sealant) respectively. The control group was treated with 75% sodium fluoride glycerine paste. Effective rates of the four groups were compared with each other. Three months later, curative effects were evaluated again. RESULTS: Effective rates in groups of C P and C P S were significantly higher than that in the other two groups( P <0.01). There were no statistically significant differences between the groups of C P and C P S ( P >0.05). Three months later, the conclusions were alike. CONCLUSIONS:GLUMA CPS desensitizing bonding system could treat dentin hypersensitivity effectively, and C P was the best composite.
