目的 探讨树脂充填器在楔状缺损修复中的应用价值.方法 楔状缺损患者126例,共计178颗患牙,随机分对照组,用普通树脂填充器进行修复;研究组用Kerr树脂充填器进行修复,观察两组修复时间、效果及塑形能力.结果 研究组填充时间、塑形能力、充填有效率明显优于对照组,P<0.05,差异有统计学意义,且工作头无沾黏填充材料的现象.结论 Kerr树脂填充器用于修复锲状缺损临床效果明显.%Objective To investigate the application value of resin filling device in the repair of wedge-shaped defects. Methods 126 cases of wedge-shaped defect patients, a total of 178 teeth, were randomly divided into control group, repaired with ordinary resin filler, study group repaired with Kerr resin filler. Observe two groups of repair time, effect and shaping ability. Results Study group's filling time, shaping ability filling were significantly better than those of control group, P<0.05. There is statistically significant difference. And the work head has not sticking phenomenon of filling material. Conclusion Kerr resin filler can use of repairing wedge-shaped defect, has obviously clinal effect.
