目的评价Vitremer树脂加强型玻璃离子修复楔状缺损前使用Gluma脱敏剂和极固宁TM,对术后牙齿敏感和远期临床疗效的影响。方法 78例患者,共243颗因楔状缺损导致牙本质过敏的牙齿,在Vitremer树脂加强型玻璃离子修复楔状缺损前,治疗组分别采用Gluma脱敏剂和极固宁TM脱敏,对照组不采取任何措施,比较术后脱敏效果,并于修复后6个月及12个月用改良的USPHS系统评价其远期临床疗效。结果术后,治疗组与对照组对外界刺激的反应有统计学差异(P<0.01);在修复成功率方面,Gluma脱敏剂组6个月成功率高于对照组,与极固宁TM组之间无统计学差异,12个月成功率Gluma脱敏剂组、极固宁TM组、对照组间均无统计学差异。结论 Vitremer树脂加强型玻璃离子修复楔状缺损前使用Gluma脱敏剂,能降低牙本质过敏的发生,且能在一定程度上提高其修复成功率。
Objective To evaluate the effect of using Gluma desensitizer and jiugangning TM before the vitremer resin reinforced wedge-shaped defect repair on the sensitivity and long-term clinical curative effect of postoperative teeth. Methods A total of 243 teeth with dentin hypersensitivity caused by wedge-shaped defect were included in 78 patients. Before vitremer resin-reinforced glass iontophoresis wedge-shaped defect, the treatment group was desensitized with Gluma desensitizer and denguning TM respectively and the control group did not take Any measures to compare postoperative desensitization, and 6 months and 12 months after repair with a modified USPHS system to evaluate its long-term clinical efficacy. Results The postoperative response of the treatment group and the control group to the external stimuli was statistically different (P <0.01). In the success rate of repair, the success rate of Gluma desensitizer group at 6 months was higher than that of the control group, There was no significant difference between the two groups. There was no significant difference between the 12-month success rate Gluma desensitizer group, the Jiulinging TM group and the control group. Conclusion The use of Gluma desensitizer before Vitremer resin reinforced wedge-shaped defect repair can reduce the incidence of dentin hypersensitivity and improve the repair success rate to a certain extent.
