摘　　要：为对比临床常用3种排龈方法的排龈效果,将270例需预备龈下肩台的单冠修复者随机分成3组(n=90),在制取印模前分别进行单线法、双线法及排龈膏法排龈,随后从印模、模型质量,牙龈出血、患者主观感觉及排龈时间方面,综合评价三者的优劣。三者在修复体质量方面无统计学差异(P=3.209),在排龈时间及患者满意度方面,排龈膏组优于排龈线组(P<0.05)。270 patients underwent single crown prosthodontics were randomly divided into 3 groups （ n = 90） and received gingival retraction with single- cord, double- cord and gingival retraction paste respectively. The prosthesis quality of the 3 groups was not statistically significant （ P = 3. 209）. The patient satisfaction was more and the gingival retraction time of the paste group was shorter than those of the cord groups （ P〈0.05）.
