目的
本研究的目的是探讨牙龈切除术和连续使用低强度激光治疗（LLLT）后的牙龈愈合。
背景数据
自20世纪60年代以来，LLLT已用于动物实验，以检查激光辐射对伤口愈合过程的影响。然而，牙科的临床试验很少，其中大多数是指第三磨牙拔除后的治疗，牙周病学领域的报道很少。
方法
选择20例牙周病患者，计划对双侧上下牙前磨牙进行牙龈切除术。手术后，一侧接受LLLT，使用685 nm波长，输出功率50 mW，能量密度4 J/cm（2）。另一侧作为对照，不接受激光照射。术后即刻和第3、7、14、21、28和35天，从临床和生物统计学角度评价愈合情况。将结果提交进行统计分析。
结果
生物统计学评价表明，激光组在21天和28天时愈合显著改善。临床评估显示激光组修复效果更好，主要是在第三天之后。
结论
LLLT是一种有效的后续治疗，似乎可以促进牙龈切除术后的愈合。
OBJECTIVE
The purpose of this study was to investigate gingival healing after gingivectomy and adjunctive use of low-level laser therapy (LLLT).
BACKGROUND DATA
LLLT has been used in animal experiments to examine the influence of laser radiation on the wound healing process since the 1960s. However, clinical trials in dentistry are scarce, and most of them refer to treatment after extraction of the third molars, with only a few reports in the area of periodontics.
METHODS
Twenty patients with periodontal disease were selected, and treatment was planned for gingivectomy to bilateral maxillary and mandibular premolar teeth. After surgery, one side was submitted to LLLT using a 685-nm wavelength, output power of 50 mW, and energy density of 4 J/cm(2). The other side was used as the control and did not receive laser irradiation. Healing was evaluated, clinically and biometrically, immediately post-surgery and at days 3, 7, 14, 21, 28, and 35. Results were submitted to statistical analysis.
RESULTS
Biometrical evaluation indicated a significant improvement in healing for the laser group at 21 and 28 days. Clinical evaluation showed better repair for the laser group, mainly after the third day.
CONCLUSION
LLLT was an effective adjunctive treatment that appeared to promote healing following gingivectomy.
