目的观察G-BOND和I-BOND自酸蚀黏结剂治疗牙齿感觉过敏症的疗效。方法选择2009年6月至2011年3月广州军区联勤部门诊部口腔科收治的不同原因引起的2度和3度牙齿感觉过敏症患者112例(164颗患牙),随机分为G-BOND组(G-BOND自酸蚀黏结剂)、I-BOND组(I-BOND自酸蚀黏结剂)和对照组(极固宁),观察各组患者治疗后即刻、6个月、12个月疗效。结果治疗后即刻,G-BOND组和I-BOND组患者牙齿感觉过敏症效果满意(成功率分别为90.5%和89.8%),治疗后6、12个月成功率均有下降。G-BOND组和I-BOND组治疗后即刻、6个月、12个月疗效同对照组差异均无统计学意义(均P>0.05)。结论自酸蚀黏结剂为一种临床上较好的治疗牙齿感觉过敏症的方法。
Objective To observe the curative effect of G-BOND and I-BOND self-etching adhesives on dental hypersensitivity. Methods 112 cases (164 teeth) of 2 degree and 3 degree dental hypersensitivity who were admitted to Department of Stomatology of Joint Department of Guangzhou Military Region from June 2009 to March 2011 were randomly divided into G- BOND group (G-BOND self-etching adhesive), I-BOND group (I-BOND self-etching adhesive) and control group Month effect. Results Immediately after treatment, the patients with G-BOND and I-BOND had satisfactory dental hyperalgesia (success rates were 90.5% and 89.8% respectively), and the success rates were both decreased at 6 and 12 months after treatment. There was no significant difference between the G-BOND group and the I-BOND group in the immediate, 6-month and 12-month follow-up (all P> 0.05). Conclusion Self-etching adhesives are a clinically preferable method of treating tooth hypersensitivity.
