62例楔状缺损修复后的临床疗效观察

Clinical observation of wedge-shaped defect repair in 62 cases

目的:观察自酸蚀粘接系统(G-BOND)应用于牙颈部楔状缺损修复的临床疗效。方法:将62例患者、174颗患牙进行随机分组,试验组采用自酸蚀粘接系统,对照组采用全酸蚀粘接系统。观察治疗后1周、6个月及12个月的疗效,并采用改良的美国公共健康部制定评定系统(USPHS)[1]进行疗效评估。结果:试验组在术后敏感程度与对照组有显著性差异(P<0.05),而在边缘密合度、继发龋、充填体脱落、牙髓病变及牙龈炎症等疗效上两组无统计学差异(P>0.05)。结论:G-BOND自酸蚀粘接剂临床疗效与全酸蚀相似,但操作更简便省时,应用于修复楔状缺损效果可靠。

Objective： To observe the clinical efficacy of self-etching bonding system G-BOND on the cervical wedge-shaped defect reparir. Methods： 62 patients （174 teeth） treated in the department were randomly divided into the experimental group that adopted self-etching bonding system （G-- BOND） and the control group that adopted the total-etching adhesive system. The efficacies of these treatments after 1 week, 6 months and 12 months were observed and evaluated by the improved assessment system set by the U. S. Department of Public Health （USPHS） . Results： The postoperative sensitivity of the patients in the experimental group was significant that of the control group （P〈0.05） ; while, there was no statistical difference in the ly better than efficacy as far as the marginal adaptation, secondary caries, filling mass loss, pulp disease and gingivitis were concerned （P〉0.05）. Conclusion： The G-BOND self-etching bonding agent has the similar clinical efficacy to the total-etching adhesive system, but its operation is easier and timesaving, and it is reliable in repairing the wedge-shaped defect.
