目的：观察新型自黏结树脂水门汀的黏结力，探讨其临床适用性。方法选择2010年5月~2011年10月在本院就诊的58例进行根管治疗的患者，随机分为试验组30例和对照组28例，试验组采用新型自黏结树脂水门汀黏结修复处理，对照组采用传统聚羧酸锌水门汀黏结修复处理，观察两组的患牙修复成功率并分别测试和记录1、3、6、12、24个月的黏结强度。结果试验组患牙修复成功率为97.1%(34/35)，对照组患牙修复成功率为94.1%(32/34)，两组比较差异无统计学意义(χ2=0.3795，P=0.5379)。1个月后，两组黏结强度比较差异无统计学意义(P>0.05)；3、6、12、24个月后，试验组的黏结强度明显高于对照组，差异有统计学意义(P<0.05)。结论相对于传统聚羧酸锌水门汀，新型自黏结树脂水门汀虽未明显提高患牙修复功率，但其黏结强度大，可以更好地增强黏结效果，值得临床推广应用。%Objective To observe the bonding power of new self-adhesive resin cement and discuss its clinical appli-cability. Methods Fifty-eight patients visited our hospital for root canal therapy from May 2010 to October 2011 were selected and divided into experimental group (n=30)and control group (n=28).In the experimental group,new self-adhe-sive resin cement for repair was applied,while in the control group,traditional zinc polycarbonoxylate cement was adopt-ed.The success rate of repair in the affected teeth was observed and the adhesive strength was measured and recorded after 1,3,6,12,24-month. Results The success rate of repair of the affected teeth in the experimental group was 97.1%(34/35),while in the control group,the rate was 94.1%(32/34),with no statistical difference (χ2=0.3795,P=0.5379).Adhe-sive strength in both groups after one month was compared,with no statistical difference (P>0.05).However,adhesive strength in the experimental group after 3,6,12,24 months was more powerful than that in the control group respectively, with statistical difference (P<0.05). Conclusion In comparison with traditional zinc polycarbonoxylate cement,new self-adhesive resin cement doesn’t improve the success rate of repair,but increases the adhesive strength,which can better strengthen the adhesive effect and is worthy of promotion and application in clinic.
