Effective disinfection of the root canals is the cornerstone of successful endodontic treatment. Diminishing the microbial load within the root canal system is crucial for healing in endodontically treated teeth. The aim of this study was to evaluate the effect of 2780 nm Er,Cr:YSGG and 940 nm diode lasers on the eradication of microorganisms from single-rooted teeth with asymptomatic apical periodontitis.
Thirty participants conforming to the inclusion criteria were randomly divided into 3 groups according to the disinfection protocol used; Conventional group: 2.5% Sodium Hypochlorite (NaOCl) and 17% EDTA solution NaOCl/EDTA, Dual laser group: 2780 nm Erbium, chromium: yttrium scandium-gallium-garnet (Er,Cr:YSGG) laser and 940 nm diode laser Er,CrYSGG/Diode, and Combined group: 17% EDTA and 940 nm diode laser EDTA/Diode. Bacterial samples were collected before and after intervention. The collected data were statistically analyzed using Friedman's test and Kruskal-Wallis test (P ≤ 0.05).
The results of the study showed that both dual laser Er,CrYSGG/Diode and combined laser EDTA/Diode groups showed significantly less mean Log10 CFU/ml of aerobic and anaerobic bacterial counts than the conventional NaOCl/EDTA group.
In this study we evaluated in vivo the bactericidal efficacy of three disinfection protocols for endodontic treatment of single-rooted teeth with apical periodontitis. The results indicated that both dual laser Er,CrYSGG/Diode and combined laser EDTA/Diode groups provide superior bactericidal effect compared to the conventional NaOCl/EDTA group.
The integration of lasers into root canal disinfection protocols has demonstrated significant bacterial reduction which might promote healing and long-term success.
有效的根管消毒是成功根管治疗的基石。减少根管系统内的微生物负荷对于根管治疗后的牙齿愈合至关重要。本研究的目的是评估 2780nmEr，Cr：YSGG 和 940nm 二极管激光对患有无症状根尖周炎的单根牙消除微生物的效果。
根据使用的消毒方案，将 30 名符合纳入标准的参与者随机分为 3 组；常规组：2.5%次氯酸钠（NaOCl）和 17%乙二胺四乙酸（EDTA）溶液 NaOCl/EDTA；双激光组：2780nm 铒，铬：钇，钪，镓，石榴石（Er，Cr：YSGG）激光和 940nm 二极管激光 Er，CrYSGG/二极管，联合组：17%EDTA 和 940nm 二极管激光 EDTA/二极管。干预前后采集细菌样本。使用 Friedman 检验和 Kruskal-Wallis 检验对收集到的数据进行统计学分析（P≤0.05）。
研究结果表明，双激光 Er，CrYSGG/二极管和联合激光 EDTA/二极管组的好氧和厌氧细菌计数的平均 Log10CFU/ml 均明显低于常规 NaOCl/EDTA 组。
在这项研究中，我们评估了三种消毒方案在治疗根尖周炎单根牙中的体内杀菌效果。结果表明，双激光 Er，CrYSGG/二极管和联合激光 EDTA/二极管组与常规 NaOCl/EDTA 组相比，提供了更好的杀菌效果。
将激光整合到根管消毒方案中已证明具有显著的细菌减少作用，这可能促进愈合和长期成功。
