摘　　要：选择楔状缺损颈部边缘位于龈下0-2 mm内、较难充填的活髓患牙120颗,分3组（n=40）：Ⅰ组：排龈线排龈;Ⅱ组：排龈膏排龈;Ⅲ组：对照组,直接充填。充填后1、2年复查,以改良的USPHS直接临床评价系统评估疗效。修复1年及2年后实验组和对照组成功率差异均有显著性,实验组之间成功率差异无显著性。120 teeth with wedge-shaped defects at subgingival depth of 0 - 2 mm were selected and divided into 3 groups（n=40）. Gingival retraction code and EXPASYL gingival retraction paste were used for gingival retraction in the 2 retraction groups,and none retraction was used in the control group. After restoration of the defects,all cases were followed up for 1 year and 2 years. The results were evaluated by modified USPHS criteria. No significant difference was detected for 1 year and 2 year successful rates between the extraction groups（P〉0. 05）. The successful rate in extraction groups was higher than that in the control group（P〈0. 05）.
