The effect of soft-laser application on postoperative pain and swelling was evaluated in a double-blind, crossover study. Twenty-five healthy adults with bilateral identically impacted lower third molars were selected for this study. The teeth were removed in two separate operations. Laser treatment was tested in comparison with placebo laser, with a 40-mW, 830-nm Biophoton laser (Roenvig Dental, Denmark). All surgical procedures and measurements were done by the same surgeon. The following features were statistically analyzed: swelling, trismus, and subjective registration of pain on a visual analog scale. No statistically significant differences were observed in comparison of the experimental side with the placebo side. It may be concluded that soft-laser treatment has no beneficial effect on swelling, trismus, and pain after third molar surgery.
在一项双盲交叉研究中评估了软激光应用对术后疼痛和肿胀的影响。本研究选取了25名双侧下颌第三磨牙均为相同阻生情况的健康成年人。牙齿在两次单独的手术中拔除。使用一台40毫瓦、830纳米的生物光子激光（丹麦Roenvig Dental公司生产）与安慰剂激光进行对照测试。所有手术操作和测量均由同一位外科医生完成。对以下特征进行了统计学分析：肿胀、牙关紧闭以及视觉模拟量表上的疼痛主观记录。实验组与安慰剂组相比未观察到统计学上的显著差异。可以得出结论，软激光治疗对第三磨牙手术后的肿胀、牙关紧闭和疼痛没有有益影响。
