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 clinical efficacy of F_ (2000) complex and BEAUTIFIL polymer in the repair of wedge-shaped defects. Methods: 40 cases of wedge-shaped defect (80 live pulp teeth) were divided into control group (F_ (2000) complex, 40) and experimental group (BEAUTIFIL polymer, 40) using a completely randomized method. Evaluate the clinical efficacy at 6, 12 and 24 months after repair. Results: At 6 months after the repair, there was no significant difference between the two groups (P> 0.05). After 12 months, the color coordination and the edge adhesion of the experimental group were better than those of the control group (P <0.05). After 24 months, Group color coordination, edge adhesion and restoration integrity better than the control group (P <0.05). CONCLUSION: The BEAUTIFIL polymer is superior to the F_ (2000) complex in repairing wedge-shaped defects, but the long-term curative effect needs further observation.
