3种材料修复楔状缺损的临床观察

目的观察3种材料修复楔状缺损的疗效。方法186例患者的518颗患牙随机分为3组,分别用GC FujiⅡ型玻璃离子(A组)、Dyract AP复合体(B组)和3M-VitremerTM光固化玻璃离子水门汀(C组)修复楔状缺损,修复后1、2年复查,观察临床疗效。结果修复后1、2年的成功率分别为:A组83.77%、63.04%,B组93.08%、80.67%;C组94.38%、89.86%。术后1年、2年C组和B组的成功率均高于A组(P<0.01)。结论Dyract AP复合体、3M-VitremerTM光固化玻璃离子水门汀修复楔状缺损的疗效比GC FujiⅡ型玻璃离子的疗效好。

Clinical observation of restoration of dental wedge-shaped defects with three different methods

Objective To observe the effects on restoring dental wedge-shaped defects with three methods. Methods 518 teeth in 186 cases with wedge-shaped defects were randomly divided into three groups which were restored with GC Fuji Ⅱ glass-ionomer（A group）, Dyract AP Cement（B group）and 3M-Vitremer glass-ionomer cement（C group）, respectively. Results The 1-year and 2-year-after-treatment successful rates of A group were 83.77% and 63.04% ,93.08 % and 80.67 % of B group,94.38 %and 89.86% of C group.The 1-year and 2-year successful rates of C group and B group were higher than those of A group. The difference was statistically significant（ P 〈 0.01 ）. Conclusion The curative effects of 3M-Vitremer glass-ionomer cement and Dyract AP Cement were superior to those of GC Fuji Ⅱglass-ionomer for restoring wedge-shaped defects.
