Abstract Objective： To investigate the effects of laser assisted treatment on chronic periodontitis in middle-aged and elderly patients. Methods： From February 2015 to September 2017， 138 patients with chronic periodontitis in the Department of Stomatology of our hospital were selected， all the patients were divided into the 69 patients in the observation group and the 69 patients in the control group accorded to the different treatment methods. The control group were given routine treatment， the observation group were given assisted therapy， and the two groups were given antibiotics treatment. The treatment cycles were observed for 3 months. Results： After treatment， the total effective rate of the observation group were 94.2%， which the observation group were significantly higher than that of the control group （69.6%） （P<0.05）. After treatment， the GI and AI indexes of the two groups were significantly lower than those before treatment （P<0.05）， and the observation group were also significantly lower than that of the control group （P<0.05）. Conclusion： The laser assisted treatment of chronic periodontitis in middle-aged and elderly patients can improve the clinical symptoms and improve the therapeutic effect， and has a good application value.

Key words： Middle-aged and elderly； chronic periodontitis； laser； gingival index.

慢性牙周炎是口腔科的一种常见病，是由菌斑生物膜所引起的慢性感染性牙周疾病[1]。其在临床上主要表现为牙槽骨吸收、牙松动、附着丧失、牙周袋形成并有炎症，由于其早期发病较为隐匿，症状不是特别突出，往往被患者所忽视，经久不治便会导致病情加重[2]。慢性牙周炎的发病率一般在35岁后显著增高，50-60岁时达高峰。传统器械治疗-超声波或手工进行刮治和根面平整是目前中老年慢性牙周炎最常用、最有效的基础治疗方法，能消除牙周袋内根面上的菌斑和牙石，但是由于解剖因素的影响，很多治疗器械难以进入，导致治疗存在局限性[3]。YAG激光被认为是牙周治疗中最有潜力的激光，Er：YAG激光是波长2900nm的固体脉冲激光，不易引起热损伤，易被水和羟磷灰石吸收形成微爆破，从而清除软硬组织而发挥治疗作用[4-5]。本文具体探讨了激光辅助治疗中老年慢性牙周炎的效果，现报道如下。
