摘　　要：探讨双线排龈法和Nd∶YAG激光排龈法的排龈效果、患者疼痛反应程度和对牙周健康的影响。将96颗患牙随机分组,即双线排龈组和Nd∶YAG激光排龈组。对石膏模型、印模及患者疼痛度进行调查,通过牙周健康指数对修复后1周、1个月、3个月的基牙牙周健康状况进行评价。两组石膏模型及印模均达到满意效果。Nd∶YAG激光排龈组的无痛率明显高于双线排龈组(P<0.05)。两组治疗后1周及1个月的探诊深度(PD)值均较治疗前降低,但Nd∶YAG激光组PD值高于双线排龈组(P<0.05)。3个月后两组PD值均恢复至治疗前水平(P>0.05)。Nd∶YAG激光组操作时间明显短于双线排龈组。两种排龈方法均可以达到理想的排龈效果。但Nd∶YAG激光具有操作简便,耗时少且无痛等优点。To investigate the influence of Nd∶YAG laser gingival retraction techniques on gingival retraction and the impact of painful reaction and periodontal local health in comparison with two- gingival retraction cords, 96 teeth are selected in clinic randomly and divided into two groups, two- gingival retraction cords group and Nd∶YAG laser gingival retraction group, observing the plaster model, impression and painful reaction. The periodontal parameters are evaluated and analyzed statistically after one week, one month and three months. The plaster models and impressions in these two groups are satisfying. The no pain rate in Nd∶YAG laser group is significantly higher than that in the two- gingival retraction cords group, the difference is statistically significant（P〈0.05）. The probing depth（PD） values one week and one month after treatment significantly decrease compared with those before treatment, and the PD values of the Nd∶YAG laser group are higher than those in the two-gingival retraction cords group, the difference is statistically significant（P〈0.05）.The PD values after three months are restored to the original level, the difference is not statistically significant（P〉0.05）. The treatment time of the Nd∶YAG laser group is significantly shorter than that in the two-gingival retraction cords group. These two methods can both reach ideal clinical effect. But the Nd∶YAG laser gingival retraction technique has shown better features in operation, time consuming and painful reaction.
