两种楔状缺损修复材料的临床效果比较

摘要

目的 探讨两种修复楔状缺损材料的应用效果.方法 将294例患者共1242颗患牙随机分为两组.实验组:149例患者648颗患牙,采用Dyract AP复合体修复.对照组:145例患者594颗患牙,采用3M-Vitemer新一代光固化玻璃离子水门汀修复.修复后1～2年进行复查,观察两组的临床效果.结果 两种修复材料均显示出优良的固位性能和边缘密合性,对牙髓和牙周组织均无刺激；实验组和对照组的成功率分别为92.59％和88.38％,两组差异具有统计学意义(P＜0.05).结论 两种材料修复楔状缺损均可获得较好的临床效果,其中复合体修复的成功率高于光固化水门汀.%Objective To evaluate the application effect of two kinds of materials for restoration of the wedge-shaped defect.Methods 294 patients with a total of 1242 teeth with wedge-shaped defect enrolled and randomly divided into two groups.648 teeth with wedge-shaped defect of 149 patients in the experimental group were repaired with the Dyract AP complex.While 594 teeth with wedge-shaped defect of 145 patients in the control group were repaired with a new generation of 3M-Vitemer light-cured glass ionomer cement.The patients were recalled 1-2 years after restoration to evaluate the clinical effects of two kinds of materials.Results Both of the two kinds of repairing materials showed excellent retention and edge sealing,and no irritation to pulp and periodontal tissue.The success rate of the experimental group and the control group were 92.59％ and 88.38％ respectively,and there was statistical difference between the success rates of the two groups (P＜0.05).Conclusion Both of the two kinds of materials for restoration of dental wedge-shaped defects in the present manuscript can obtain good clinical effect,but the success rate in reparing the wedge-shaped defect with the complex is higher than that with light-cured cement material.
