3MP90粘结系统与精氨酸牙膏治疗牙本质过敏症疗效观察

Observation of efficacy of comparison between 3MP90 bonding system and arginine toothpaste on dental hypersensitiveness

目的:观察评价3MP90粘结系统与精氨酸牙膏对比治疗牙本质过敏症的疗效。方法:将120例牙本质过敏症患者随机分为3MP90组、精氨酸组和对照组各40例,3MP90组患者3MP90粘结系统进行脱敏治疗,精氨酸组采用8%精氨酸抗敏牙膏,对照组采用0.9%氯化钠溶液涂擦敏感牙面作为安慰剂进行治疗。观察比较三组患者治疗前、治疗后1月、2月、3月的治疗效果和压力阈值、可视疼痛评分(VAS)以及Schiff冷空气敏感指数等牙本质过敏指标。结果:3MP90组和精氨酸组各项指标均显著优于对照组(P<0.05);3MP90组治疗后2、3月总有效率分别为90.0%、85.0%,分别高于精氨酸组的70.0%、65.0%,差异具有统计学意义(P<0.05);3MP90组治疗后2月、3月压力阈值高于精氨酸组(P<0.05),治疗后3月的VAS评分、Schiff指数均分别低于精氨酸组(P<0.05),两组治疗后1月的VAS评分、Schiff指数比较差异无统计学意义(P>0.05)。结论:3MP90和精氨酸对牙本质过敏症均有治疗效果,但与精氨酸抗敏牙膏相比,3MP90粘结系统的临床效果更为显著,长期疗效更优。

Objective:To observe and evaluate the efficacy of comparison between 3MP90 bonding system and arginine toothpaste on dental hypersensitiveness.Methods:120 patients with dental hypersensitiveness were randomly divided into 3MP90 group,arginine group and control group with 40 cases in each,3MP90 group was given 3MP90 bonding system in desensitization treatment,arginine group was given 8%arginine toothpaste while the patients of control group were treated with 0.9%sodium chloride solution to rub sensitive tooth surface as a placebo reference.Observed and compared the efficacy and hypersensitivity indicators such as pressure threshold,visual analogue scale(VAS)and Schiff cold air sensitivity index before the treatment and 1,2,3 months after treatment.Results:The indexes of 3MP90 group and arginine group were significantly better than those of the control group(P<0.05).The effective rates 2 and 3 months after treatment of 3MP90 group were 90.0%and 85.0%,higher than 70.0%and 65.0%of arginine group,and the difference was statistically significant(P<0.05).The pressure threshold of 3MP90 group 2 and 3 months after treatment was higher than that of arginine group(P<0.05).The VAS score and Schiff index 3 months after treatment of 3MP90 group were lower than those of the arginine group(P<0.05).There was no significant difference between two groups 1 month after treatment(P>0.05).Conclusion:3MP90 and arginine have therapeutic effect on dental hypersensitiveness,but the clinical effect of 3MP90 bonding system is more remarkable than that of arginine anti-hypersensitiveness toothpaste.The long-term effect of 3MP90 is better and it is worthy of clinical application.
