目的：观察Er，Cr：YSGG（铒和铬、钇、钪、镓、石榴）激光治疗急性牙周脓肿的短期临床疗效。方法将入选的58名急性牙周脓肿患者随机分为实验组和对照组，实验组28名，对照组30名。所有患者给于龈上洁治、龈下刮治及根面平整。对照组给予生理盐水袋内冲洗置盐酸米诺环素软膏，而实验组应用Er，Cr：YSGG激光进一步进行牙周袋内清创及肿胀控制，而后给予生理盐水袋内冲洗。记录并分析基线及治疗后3d时的疼痛程度、牙周袋溢脓情况、牙齿松动度。结果治疗后两组各项指标均较治疗前有所改善（P<0.05）；实验组疼痛的改善程度优于对照组，差异具有显著性（P<0.05）；两组间治疗疗效差异无显著性（P>0.05）。结论 Er，Cr：YSGG激光治疗急性牙周脓肿具有较好的作用。

Objective To investigate the Clinical effects of Er, Cr:YSGG on acute periodontal abscess. Methods 58 patients with acute periodontal abscess were divided into experimental group (28 cases) and control group (30 cases). All patients were treated with supragingival scaling , subgingival scaling and root planning. In addition Er, Cr:YSGG was administered in the experimental group. After periodontal rinsing with normal saline,control group were administered minocycline locally. The pain degree,mobility degree , purulent exudation were evaluated before treatment and 3 days later. Results Between both groups, a statistically significant improvement of the indicators was found after therapy (P<0.05). Results between experimental and control groups showed a statistically significant difference in pain (P<0.05).The success rates showed no statistical difference between them either (P>0.05). Conclusion Er, Cr:YSGG is effective in the treatment of acute periodontal abscess.
