本临床试验评估了Gluma Dentin Bond在准备接受完整铸型修复的牙齿中抑制牙本质敏感性的能力。20名患者提供了76颗牙齿。在牙齿准备后，用无菌水（对照组）或两次30秒的Gluma牙本质黏合剂（测试）涂在完整或去除的涂抹层上。14天后召回患者，测试制备好的牙本质对压缩空气、渗透刺激（饱和CaCl2溶液）的敏感性，并在控制负荷下通过划痕试验进行触觉刺激。与对照组相比，两组对测试刺激的牙齿数量明显减少（P < 0.01）。在使用Gluma治疗之前，涂抹层完整或去除的牙齿之间没有差异。
This clinical trial assessed the ability of Gluma Dentin Bond to inhibit dentinal sensitivity in teeth prepared to receive complete cast restorations. Twenty patients provided 76 teeth for the study. Following tooth preparation, dentinal surfaces were coated with either sterile water (control) or two 30-second applications of Gluma Dentin Bond (test) on either intact or removed smear layers. Patients were recalled after 14 days for a test of sensitivity of the prepared dentin to compressed air, osmotic stimulus (saturated CaCl2 solution), and tactile stimulation via a scratch test under controlled loads. A significantly lower number of teeth responded to the test stimuli for both Gluma groups when compared to the controls (P less than .01). No difference was noted between teeth with smear layers intact or removed prior to treatment with Gluma.
