摘要
目的:对比不同操作在后牙树脂充填中的临床疗效。方法:随机选择临床需要充填的Ⅱ类深洞133例(189颗)。实验分为4组,分别采用制备釉质斜面和不制备斜面、水平充填和斜方充填,评价充填后的成功率、边缘密合度以及固位情况。结果:充填后1、6、12个月,Ⅳ组在成功率、边缘密合度及固位性方面较I组有显著性差异(P<0.05)。结论:复合树脂在后牙Ⅱ类深洞的充填中制备釉质斜面、斜方充填的临床疗效明显优于不制备斜面和水平充填。
Objective To evaluate the clinical effect of posterior composite restorations with different operation methods.Methods 133 class Ⅱ deep posterior cavities were randomly selected and divided into 4 groups with non-bevel/bevel preparation,horizontal/oblique filling.The success rate,marginal adaptation and retention form were evaluated after restoration.Results After 1,6,12 month of restoration,group IV had significant differences in success rate,marginal adaptation and retention form,compared with group I（P0.05）.Conclusion The clinical effect of posterior composite restoration with bevel preparation and oblique filling was better than restoration with non-bevel preparation and horizontal filling.
