劲润牙本质保护膜对前牙瓷贴面修复后过敏症及固位力影响的临床观察

Clinical observation of anaphylaxis and retention influence to the front teeth after porcelain laminate veneer preparation with jetline dentin protective film

目的观察劲润牙本质保护膜对瓷贴面牙体预备后的牙过敏及固位力的影响。方法将82颗前牙在粘接瓷贴面之前随机分成2组,实验组基牙预备后涂布劲润牙本质保护膜后光固化树脂水门汀粘接,对照组直接光固化树脂水门汀粘接,于2年后复诊,详细记录修复体的完整性、边缘密和性及基牙的敏感性。结果 2组在修复体的完整性及边缘密和性差异无统计学意义(P>0.05)。2组基牙的敏感性比较有统计学意义(P<0.05)。结论涂布劲润牙本质保护膜后在减少全瓷贴面预备后基牙牙本质敏感的同时,对瓷贴面的固位力无影响。

Objective To observe the anaphylaxis and retention influence to the porcelain laminate veneer prepared teeth with jetline dentin protective film. Methods 82 front teeth were divided into two groups at random before bonding to the porcelain laminate veneer. After the preparation, teeth in experimental group coating jetline dentin protective iflm before bonding by light cured resin cement, and the teeth in control group bonding by light cured resin cement directly, were examined after 2 years to record the completeness of the restored teeth, the edge adaptation and the sensitivity of the target teeth. Results The comparison of two groups in the completeness of the restored teeth and the edge adaptation had no statistical signiifcance （P〉0.05）. The comparison of two groups in the sensitivity of the target teeth had statistical signiifcance （P〈0.05）. conclusion There’s a decrease on the sensitivity of the target teeth and no inlfuence on the bond with the porcelain laminate veneer after coating jetline dentin protective iflm.
