This study aims to compare the bactericidal efficacy of different Er,Cr:YSGG disinfection methods, particularly combined application of Er,Cr:YSGG and Diode laser. Root canal disinfection is important for long-term endodontic success. Different laser systems are proposed as alternatives to conventional techniques in bacterial elimination. Ninety-five straight, single-rooted premolars with similar canal dimensions were selected. After the mechanical preparation, the samples were sterilized, and root canals were infected with . The samples were randomly divided into five groups ( = 15): 5% NaOCl, Er,Cr:YSGG, Er,Cr:YSGG +5% NaOCl, Er,Cr:YSGG + Diode, and control group. The maximal bacterial elimination was observed in Er,Cr:YSGG + NaOCl group ( < 0.005). More bacteria were found in Er,Cr:YSGG and Er,Cr:YSGG + Diode groups compared with 5% NaOCl group ( < 0.005). Marginal significance was detected between the Er,Cr:YSGG group and the Er,Cr:YSGG + Diode group ( = 0.091). The most successful elimination was obtained from laser-activated irrigation group. As combined application of Er,Cr:YSGG and Diode laser gives suggestive results, further studies with larger sample sizes are needed to clarify the outcome.
钇钪镓石榴石（Er,Cr:YSGG）消毒方法的杀菌效果，特别是Er,Cr:YSGG与二极管激光联合应用的效果。根管消毒对于牙髓病的长期成功治疗至关重要。不同的激光系统被提议作为传统细菌消除技术的替代方法。选择了95颗根管尺寸相似的直单根前磨牙。机械预备后，对样本进行灭菌，并使根管感染……。样本随机分为五组（每组n = 15）：5%次氯酸钠（NaOCl）组、Er,Cr:YSGG组、Er,Cr:YSGG + 5% NaOCl组、Er,Cr:YSGG + 二极管激光组和对照组。在Er,Cr:YSGG + NaOCl组观察到最大的细菌清除率（P < 0.005）。与5% NaOCl组相比，在Er,Cr:YSGG组和Er,Cr:YSGG + 二极管激光组中发现更多细菌（P < 0.005）。在Er,Cr:YSGG组和Er,Cr:YSGG + 二极管激光组之间检测到边缘显著性（P = 0.091）。激光激活冲洗组获得了最成功的细菌清除效果。由于Er,Cr:YSGG与二极管激光联合应用给出了提示性结果，需要进一步进行更大样本量的研究以明确结果。
