Periodontitis is an inflammatory periodontal disease that leads to tooth loss. Recently laser has been introduced as an alternative treatment for periodontitis. The aim of the present study was to compare the effect of Erbium-doped Yttrium Aluminum Garnet (Er:YAG) laser with ultrasonic scaler in patients with moderate chronic periodontitis. In this randomized single-blind clinical trial, 27 patients with moderate chronic periodontitis were selected. One quadrant of the patients was treated by Er:YAG laser and the other one by ultrasonic scaler. Clinical parameters, including periodontal pocket depth (PPD), papillary bleeding index (PBI) and clinical attachment level (CAL) were measured before, as well as 6 and 12 weeks after treatment. Data were analyzed by SPSS 20 software using Friedman test, paired t test, independent t test and Mann-Whitney test. The significance level was set at 0.05. The means of clinical parameters in both groups were significantly improved in the first and second follow-ups ( < 0.001). Although the means of PPD, PBI and CAL were slightly higher in the laser group than in the ultrasonic group, the differences were not statistically significant between these two groups ( > 0.05). Although both ultrasonic scaler and Er:YAG laser could effectively improve clinical periodontal parameters, the results did not reveal the superiority of Er:YAG laser over ultrasonic scaler or vice versa.
牙周炎是一种会导致牙齿脱落的炎症性牙周疾病。最近，激光已被引入作为牙周炎的一种替代治疗方法。本研究的目的是比较掺铒钇铝石榴石（Er:YAG）激光与超声洁治器对中度慢性牙周炎患者的治疗效果。在这项随机单盲临床试验中，选取了27例中度慢性牙周炎患者。患者的一个象限接受Er:YAG激光治疗，另一个象限接受超声洁治器治疗。在治疗前以及治疗后6周和12周测量临床参数，包括牙周袋深度（PPD）、龈乳头出血指数（PBI）和临床附着水平（CAL）。使用SPSS 20软件，通过Friedman检验、配对t检验、独立t检验和Mann-Whitney检验对数据进行分析。显著性水平设定为0.05。在第一次和第二次随访中，两组的临床参数均值均有显著改善（<0.001）。虽然激光组的PPD、PBI和CAL均值略高于超声组，但两组之间的差异无统计学意义（>0.05）。虽然超声洁治器和Er:YAG激光都能有效改善临床牙周参数，但结果并未显示Er:YAG激光优于超声洁治器，反之亦然。
