We evaluated the clinical usefulness of an erbium:YAG laser for soft tissue surgery, and scaling. Thirty-one patients with soft tissue lesions (13 males and 18 females from 24 to 71 years old), and 60 patients with calculus deposits (21 males and 39 females from 19 to 72 years old) were treated with the laser. The clinical parameters evaluated were pain, redness, swelling of the gingiva, and the subjective patient comfort parameters including uneasiness with the sound and vibration associated with laser treatment. Additionally, hemorrhage and wound healing during and after the surgery, the roughness of the root surface after scaling, and the effectiveness of scaling using the laser were examined. Laser surgery caused less hemorrhage and resulted in better wound healing when compared with conventional methods. It was easy to remove calculi from the root surface with the laser in 95% of the cases. Although the scaled site showed some irregularity, it was not clinically significant in 98% of the cases. Only a few patients complained about the unpleasant sound and vibration. There were no complications or side effects during this clinical trial. Thus, this study suggests that an Er:YAG laser is useful for soft tissue surgery and scaling.
我们评估了铒钇铝石榴石激光在软组织手术及洁治中的临床实用性。对31例软组织病变患者（13例男性，18例女性，年龄24至71岁）以及60例有牙石沉积的患者（21例男性，39例女性，年龄19至72岁）进行了激光治疗。评估的临床参数包括疼痛、牙龈发红、肿胀，以及患者主观舒适度参数，如对激光治疗相关声音和振动的不适感。此外，还检查了手术期间及术后的出血和伤口愈合情况、洁治后牙根表面的粗糙度以及使用激光洁治的效果。与传统方法相比，激光手术出血更少，伤口愈合更好。在95%的病例中，使用激光很容易从牙根表面去除牙石。尽管洁治部位显示出一些不规则，但在98%的病例中，这在临床上并无显著意义。只有少数患者抱怨了不愉快的声音和振动。在该临床试验期间没有并发症或副作用。因此，本研究表明铒钇铝石榴石激光对软组织手术和洁治有用。
