摘　　要：目的观察邻牙邻面去釉对树脂充填重建Ⅱ类洞邻接关系的临床效果。方法在选取的274颗邻牙邻面形态异常的Ⅱ类洞树脂充填修复患牙中,充填前应用邻面去釉技术对邻牙形态异常的邻面进行修整的邻牙邻面去釉组105颗,未进行邻牙修整的常规组169颗。充填后2周、12个月,对2组邻面形态和食物嵌塞的2项指标进行评价,并进行统计学分析。结果术后2周、12个月复查,邻牙邻面去釉组邻面形态评价满意率均为94.3%,常规组均为80.5%,差异有统计学意义(P<0.05);邻牙邻面去釉组食物嵌塞满意率分别为89.5%和88.6%,常规组分别为79.9%、78.1%,差异有统计学意义(P<0.05)。结论对伴有邻牙邻面形态异常的后牙Ⅱ类洞,充填时配合邻牙邻面去釉修整,可以提高治疗的满意率。Objective To study the clinical effect of interproximal enamel reduction of adjacent teeth for the proximal contacts in Class Ⅱ composite resin restorations. Methods Two hundreds and seventy-four molars and premolars of Class Ⅱ composite resin restorations,of which adjacent surfaces of adjacent teeth exists abnormal morphology,were collected,and they were divided into 2 groups： IPR group and control group. The interproximal enamel reduction treatments were applied in IPR group before filling. For the two groups,the satisfaction rates of adjacent surface morphology and food impaction were evaluated after 2 weeks and 12 months,respectively. All data were analyzed by chi-square test. Results In the IPR group,the satisfaction rates of adjacent surface morphology were 94. 3%,in the control group,they were 80. 5%,the difference was statistically significant（ P〈0. 05）; the satisfaction rates of food impaction in IPR group were 89. 5% and 88. 6%,in the control group,they were 79. 9% and 78. 1%,the difference was statistically significant（ P〈0.05）. Conclusion The interproximal enamel reduction of adjacent teeth can improve the satisfaction rate of Class Ⅱ cavity of posterior teeth,which adjacent surfaces of adjacent teeth exists abnormal morphology.
