CO2激光、LD激光联合治疗牙龈瘤46例疗效观察

目的：研究CO2激光、LD激光联合治疗牙龈瘤及保存牙体组织的临床疗效。方法：对46例口腔牙龈瘤患者发病的年龄，性别，好发部位进行分析，采用CO2激光、LD激光联合治疗机，先用CO2激光束切割肿瘤，而后CO2激光气化肿瘤波及牙齿的牙周膜，术后第二天用LD激光，每日一次，每次15分钟，连续5天照射手术创面。结果：46列牙龈瘤患者，42例一次治疗痊愈，4例复发，二次手术后无复发，手术疗效、治愈率100％。结论：CO2激光、LD激光联合切除牙龈瘤与传统的手术方法，治疗疗效机理进行了对照，其特点是保存了肿瘤波及的牙齿，不造成组织缺损，还具有手术时间短，出血少，愈合快等优点。

Treatment of Epulis with CO2 Laser and LD Laser:Clinical Report of 46 Cases

s: Objective: To evaluate the clinical results of treating epulis with CO_2 laser and LD laser and concomitant preservation of teeth in 46 cases.Methods: The age, sex and sites of 46 patients with epulis were analysed. Laser instrutment produced by Fujian Normal University was used for treatment. CO_2 laser beam was used to cut the tumor,then to vaporize the involved periodontal membrane by the tumor. LD laser was used 2 days after CO_2 laser surgery to irradiate the surgical fields for 15 minutes per day for 5 days. Results: Of 46 patients,42 were cured by one course of treatment. The overall cure rate was 100%.Conclusions: Treating epulis with CO_2 laser and LD laser can eradicate the tumor and preserve the involved teeth without tissue defects. The surgical time is short with minimal bleeding and rapid wound healing.
