摘　　要：目的:系统评价激光排龈法在固定修复应用中的临床效果。方法:计算机检索PubMed,The Cochrane Library,EMbase,Scopus,Web of Science,CBM,CNKI,WanFang Data,VIP数据库,收集建库至2020年2月与激光排龈法与排龈线排龈法比较的随机对照试验。由两名研究者独立筛选文献,评价研究质量和提取相关数据,采用Rev-Man5.3软件进行Meta分析。结果:最终纳入7个随机对照试验,共422名患者,530颗牙齿。经过亚组分析后,Meta分析结果显示激光排龈组可减少患者疼痛程度(无痛[MD=95.57,95%CI(50.73,180.06),P<0.00001],轻度疼痛[MD=0.02,95%CI(0.01,0.04),P<0.00001]和中度疼痛[MD=0.10,95%CI(0.02,0.44),P=0.002]),术中牙龈止血效果[MD=9.31,95%CI(4.70,18.41),P<0.00001],术后预备体满意度[MD=3.12,95%CI(1.45,6.75),P=0.004],印模满意度[MD=2.06,95%CI(1.10,3.87),P=0.02]和模型满意度[MD=2.04,95%CI(1.14,3.67),P=2.04],术后1周后牙龈健康状况[MD=2.53,95%CI(1.37,4.66),P=0.003]均优于排龈线排龈组,且比较差异均有统计学意义。结论:在固定修复应用中,激光排龈法在减轻患者疼痛程度,术中牙龈止血效果,医师对预备体、印模、模型满意度,术后1周牙龈健康状况,均优于排龈线排龈法,对固定义齿修复临床效果较好。受纳入研究质量和随访时间的限制,此结论还需要更高质量、大样本、更长随访时间的随机对照试验来进一步验证。Objective:To systematically evaluate the clinical effects of gingival retraction with laser.Methods:Use computer to search randomized controlled trials comparing laser gingival retraction and gingival retraction line in PubMed,Cochrane Library,EMbase,Scopus,Web of Science,CBM,CNKI,WanFang Data,VIP database and collected the database until February 2020.Two researchers independently screened the literature,evaluated the quality of the researches,and extracted relevant data.Meta-analysis was performed using RevMan 5.3.Results:Seven randomized controlled trials involving 422 patients and 530 teeth were included.After the subgroup analysis,the meta-analysis results showed that the laser gingival removal group reduced the pain of the patients(no pain[MD=95.57,95%CI(50.73,180.06),P<0.00001],mild pain[MD=0.02,95%CI(0.01,0.04),P<0.00001]and moderate pain[MD=0.10,95%CI(0.02,0.44),P=0.002]),gingival hemostatic effect during surgery[MD=9.31,95%CI(4.70,18.41),P<0.00001],postoperative preparation satisfaction[MD=3.12,95%CI(1.45,6.75),P=0.004],impression satisfaction[MD=2.06,95%CI(1.10,3.87),P=0.02]and model satisfaction[MD=2.04,95%CI(1.14,3.67),P=2.04],gum health after 1 week[MD=2.53,95%CI(1.37,4.66),P=0.003]were better than the gingival line and gingival line group,and the differences were statistically significant.Conclusion:In fixed restoration applications,the laser gingival retractionmethod reduces the pain of patients,improves the hemostatic effect of the gums during the operation andthe physician’s satisfaction with the preparation,the impression,the model,and the gingival health status at 1 week after surgery,the effect is better than the gingival retraction line method.which is beneficial to the clinical effect of fixed denture restoration.Limited by the quality of the included studies and the follow-up time,this conclusion needs to be further validated with randomized controlled trials of higher quality,larger samples,and longer follow-up time.
