To evaluate whether laser has got any advantage over electrocautery in performing gingivectomy procedure.
This was randomized split mouth prospective study where 17 patients having symmetrical gingival hyperplasia were treated with electrocautery and laser on each side. Intra- and postoperative parameters assessed were duration of surgery, bleeding, tissue sticking, postoperative pain and healing. The results were statistically analyzed and compared.
There were 7 Females and 10 Males with a mean age of 28.2 ± 11.6 years. The mean time taken on the laser and electrocautery was 16 (±8.05) and 16.7 min (±9.86) respectively and the difference was not significant. On laser side, there was no bleeding in 3 (17.6%) and self limiting in 14 patients (82.4%) whereas electrocautery side, there was no bleeding in 2 (11.8%) and self limiting in 15 patients (88.2%). Both electrocautery and laser were comparable regarding ease of use during gingivectomy procedure. Charring was observed on both sides although there was more charring on the laser side. Fibrinous slough was present on both sides at 24 h. Difference in healing was not significant at various time intervals. There were no significant difference in postoperative pain experienced by the patients among the laser and cautery group at different time intervals.
Both techniques with proper adhesion to safeguards, can be used to remove gingival overgrowth with equal efficiency and wound healing capacity. There is no advantage of diode laser over electrocautery in performing gingivectomy.
评估在进行牙龈切除术时，激光相对于电灼术是否具有任何优势。
这是一项随机双侧对照前瞻性研究，17例患有对称性牙龈增生的患者每侧分别接受电灼术和激光治疗。评估的术中及术后参数包括手术持续时间、出血情况、组织粘连、术后疼痛和愈合情况。对结果进行统计学分析和比较。
有7名女性和10名男性，平均年龄为28.2±11.6岁。激光治疗和电灼术的平均用时分别为16（±8.05）分钟和16.7分钟（±9.86），差异不显著。在激光治疗侧，3例（17.6%）无出血，14例（82.4%）为自限性出血；而在电灼术侧，2例（11.8%）无出血，15例（88.2%）为自限性出血。在牙龈切除术过程中，电灼术和激光在易用性方面相当。两侧均观察到碳化，不过激光侧碳化更多。24小时时两侧均有纤维蛋白性痂皮。在不同时间间隔，愈合差异不显著。激光组和电灼术组患者在不同时间间隔经历的术后疼痛无显著差异。
两种技术在严格遵守安全措施的情况下，均可用于去除牙龈过度生长，效率和伤口愈合能力相当。在进行牙龈切除术时，二极管激光相对于电灼术并无优势。
