摘　　要：目的:评价渗透树脂治疗老年牙齿磨损继发牙本质过敏患者的效果,并阐明其作用原理。方法:将40例受试者随机分为对照组和实验组,每组20例。实验组患者使用Icon渗透树脂,对照组患者使用3M Adper easy one自酸蚀粘结剂。采用数字化疼痛评判法(VAS)评价治疗前、治疗即刻、治疗后1个月和治疗后3个月受试者的牙齿VAS评分。体外通过扫描电镜观察渗透树脂对牙本质小管的渗透作用。结果:2组患者治疗后即刻、治疗后1个月和治疗后3个月VAS评分均较治疗前明显降低(P<0.05),牙本质过敏症状明显减少;与对照组比较,实验组患者治疗后1个月、治疗后3个月VAS评分下降(P<0.05)。扫描电镜观察,渗透树脂在牙齿表面形成封闭,并在牙本质小管中渗透。结论:渗透树脂对老年人牙齿磨耗导致牙本质过敏有明显效果,可用于临床治疗。Objective To evaluate the effect of penetrating resin treatment on the elder patients with secondary dentin sensitivity following tooth abrasion,and to clarify its function principle.Methods 40 subjects were randomly divided into control and experimental groups（n=20）,and the patients in experimental group were treated with icon penetrating resin,and the patients in control group were treated with 3M adper easy oneselfetching adhesives.The visual analogue scale（VAS）method was used to evaluate the VAS scores of teeth of the patients in two groups at different periods,such as before treatment,right after treatment,1 month after treatment and 3month after treatment.The osmosis of resin for dentin tubule was observed by scanning electron microscope in vitro.Results Compared with before treatment,the VAS scores of the patiants in two groups1 month after treatment and 3 months after treatment were significantly decreased（P〈0.05）.Compared with control group,the VAS scores of the patients in experiment group 1 month after treatment and 3 months after treatment were decreased（P〈0.05）.The scanning electron microscope results showed that the penetrating resin formed a close in the tooth surface and penetrated in the dentin tubule.Conclusion Penetrating resin can be used as the dentin sensitivity treatment in the elderly,and it has apparent effect.
