目的比较G-BOND、I-BOND自酸蚀粘结剂与常规抗敏药物极固宁治疗牙本质过敏症的疗效差异。方法将270颗牙本质过敏症的牙齿随机分为3组,分别采用G-BOND自酸蚀粘结剂、I-BOND自酸蚀粘结剂和极固宁3种药物进行脱敏治疗。观察治疗后即刻、1个月的临床疗效及随访6个月的远期疗效。结果在治疗后即刻、1个月时G-BOND组和I-BOND组与常规药物对照组比较,组间差异无统计学意义(P>0.05)。但是治疗后6个月,G-BOND组和I-BOND组的远期疗效更为理想,其总有效率的降幅值小于对照组(P<0.05)。结论 G-BOND组和I-BOND组的近期疗效肯定,远期疗效也较为理想,随着时间的推移其临床疗效持续较久。
Objective To compare the curative effects of G-BOND, I-BOND self-etching adhesive and conventional anti-allergy jingguning on dentine hypersensitivity. Methods 270 teeth with dentin hypersensitivity were randomly divided into three groups and treated with G-BOND self-etching adhesive, I-BOND self-etching adhesive and Agmatine for desensitization. Observed immediately after treatment, 1 month clinical efficacy and follow-up of 6 months long-term efficacy. Results In the G-BOND group and the I-BOND group, there was no significant difference between the two groups (P> 0.05) immediately after treatment and at 1 month. However, the long-term efficacy of G-BOND group and I-BOND group was better than that of control group (P <0.05) 6 months after treatment. Conclusions The short-term curative effect of G-BOND group and I-BOND group is definite, and the long-term curative effect is also ideal. As time goes on, the clinical curative effect lasted longer.
