摘要
目的:对比F_(2000)复合体和BEAUTIFIL聚合体修复楔状缺损的临床疗效。方法:采用完全随机法将40例楔状缺损患者(80颗活髓牙)分为对照组(F_(2000)复合体,40颗)和实验组(BEAUTIFIL聚合体,40颗),采用改良USPHS系统评价修复后6、12、24个月时的临床疗效。结果:修复后6个月,两组疗效无明显差异(P>0.05);12个月后,实验组色泽协调性、边缘密合度优于对照组(P<0.05);24个月后,实验组色泽协调性、边缘密合度和修复体完整度优于对照组(P<0.05)。结论:BEAUTIFIL聚合体修复楔状缺损的疗效优于F_(2000)复合体,但远期疗效上需要进一步观察。
Objective： To compare the effects of F2000 composite and BEAUTIFIL polymer for repair of dental wedge-shaped defects. Methods： Eighty teeth with wedge-shaped defects obtained from 40 patients were randomly assigned to be treated with F2000 composite （control group, n = 40） and BEAUTIFIL polymer （treatment group, n =40）. The efficacy following repair was determined by using modified USPHS criterion after 6,12,24 months. Results： No significant between-group difference was found at month 6 （ P 〉 0.05 ）. The treatment group yielded preferential matching of color and marginal discrepancy as compared with control group at year 1 （ both P 〈 0.05 ） and the addition of restoration integrity at year 2 （ all P 〈 0.05 ）. Conclusion： BEAUTIFIL polymer appears as a preferential material for dental wedged-shaped defects as compared with F2000 composite yet needs to be tested in terms of prolonged therapy.
