自60年代开始,激光在医学上被广泛地应用,近些年来激光技术在口腔科也开始应用于临床。90年代开始以镓、铝、砷二极体激光器为光源的低能量半导体激光在丹麦、日本研制成功,应用于临床收到了满意的效果。1996年浙江省医疗器械研究所麦迪医疗器械开发公司推出激光功率为150MWZLD-200型半导体激光口腔治疗仪,在我院临床应用,对复发性阿弗它溃疡有比较确切的止痛,促进愈合功能。特报道如下: 1 资料和方法 1.7 门诊患者120例,住院病例1例,男性42人,女性79人,年龄最小12岁,最大75岁,平均年龄40.5岁。其中领导干部4例,科技人员30例,工人42例,农民15例,学生4例,其他人员26例。1.2 适应症:121例病例均为复发性阿弗它溃疡反复发作已超过3年以上,再次发作时间为1-3天的病例。 1.3 方法:采用浙江麦迪医疗器械开发公司研制的 Since the 1960s, lasers have been widely used in medicine. In recent years, lasers have also been applied clinically in dentistry. Since the 1990s, low-energy semiconductor lasers using gallium, aluminum and arsenic diode lasers as light sources have been successfully developed in Denmark and Japan and have been used clinically for satisfactory results. In 1996, the Medical Device Research Institute of Zhejiang Province, Maddie Medical Device Development Co., Ltd. introduced a laser power of 150MWZLD-200 semiconductor laser oral cavity therapeutic apparatus. It has clinical application in our hospital and has definite analgesic and recurrent healing effects on recurrent aphthous ulcer. Special reports are as follows: 1 Materials and Methods 1.7 outpatients 120 cases, 1 hospitalized cases, 42 males and 79 females, the youngest 12 years old, maximum 75 years old, average age 40.5 years old. Among them, there are 4 leading cadres, 30 scientific and technical personnel, 42 workers, 15 peasants, 4 students and 26 other personnel. 1.2 indications: 121 cases were recurrent aphthous ulcer recurrent episodes for more than 3 years, the time of another attack for 1-3 days. 1.3 Methods: Zhejiang Medway Medical Device Development Company developed
