摘　　要：目的观察含肾上腺素排龈线修复牙颈部楔状缺损的临床疗效。方法选取唐山市协和医院2011年1月—2013年11月收治的唇颊面牙颈部楔状缺损患者120例,将其随机分为治疗组(60例)和对照组(60例),分别采用0.1%肾上腺素排龈线和不含药排龈线进行治疗,以排龈前1 d、排龈后0.5 h、1、3、7、14 d和1个月为观察点,测定龈沟液(GCF)量、天冬氨酸转氨酶(AST)和碱性磷酸酶(ALP)水平变化。结果两种排龈方法排龈效果没有统计学差异(P>0.05);两组患者排龈后0.5 h GCF量均有所增加,排龈后1、3 d与排龈前比较差异均显著(P<0.05);排龈后的0.5 h和1、3 d两组患者GCF中AST、ALP均有明显增高的趋势,1、3 d与排龈前比较,差异均具有统计学意义(P<0.05);对照组出血率(43.3%)高于治疗组(3.3%),差异有统计学意义(P<0.05)。结论两种排龈方法对牙周组织都存在一定损伤,但均可恢复;肾上腺素排龈线更有利于止血,降低出血发生率。Objective To observe the clinical efficacy of gingival retraction cord containing epinephrine in restoring cervical abrasion lesions. Methods The patients（120 cases） diagnosed with cervical abrasion lesions in Tangshan Union Medical College Hospital from January 2011 to November 2013 were randomly divided into treatment（60 cases） and control（60 cases） groups. The patients in the treatment group were treated with gingival retraction cord containing epinephrine while the patients in the control group were treated with pure cord. The quantity of gingival crevicular fluid（GCF） and the activities of aspartate aminotransferase（AST） and alkaline phosphatase（ALP） in GCF were observed 1 d before treatment, and 0.5 h, 1, 3, 7, 14, and 28 d after treatment. Results There were not significant difference（P〈0.05） between the two groups. The quantity of GCF in patients of two groups increased 0.5 h after treatment. The quantity of GCF 1 and 3 d after treatment in the treatment group was more than that in the control group with significant difference（P〈0.05）. The quantities of AST and ALP in GCF were significantly higher 0.5 h, 1, and 3 d after treatment. The quantities of AST and ALP in GCF 1 and 3 d after treatment in the treatment group were more than that in the control group with significant difference（P〈0.05）. The bleeding rate in the control group（43.3%） was higher than the observed group（3.3%） with significant difference（P〈0.05）.. Conclusion Both techniques caused a temporary inflammation in periodontal tissue. Gingival retraction cord containing epinephrine is more conducive to stop bleeding, and reduce the incidence of bleeding.
