In root canal treatment, final root canal irrigation plays an essential role in removing smear layers, especially inorganic components, in order to achieve hermetic obturation of the root canal system. This study aimed to evaluate the root canal cleanliness, sealer penetration, and apical sealing ability of the root canal system following final irrigation using chelating agents, namely nano-chitosan, which was compared to EDTA and novel silver citrate (NSC).
This study used 135 premolars, which were divided into three evaluations: root canal cleanliness, sealer penetration, and apical sealing ability. Teeth were assigned into three groups. Group 1: EDTA, group 2: NSC, and group 3: nano-chitosan. Scanning Electron Microscope (SEM) was used to evaluate root canal cleanliness and apical sealing ability. A stereo microscope was utilized to evaluate sealer penetration. The root canal cleanliness data were analysed using the Chi-Square test, whereas sealer penetration and apical sealing ability data were analysed with a two-way ANOVA and LSD Post-Hoc test with a significance level of 95%.
In the root canal cleanliness evaluation, all three final irrigation solutions showed similar cleanliness of the root canals (p>0.05). In the evaluation of sealer penetration and apical sealing ability, nano-chitosan produced the highest sealer penetration and apical sealing ability compared to EDTA and NSC (p<0.05).
All final irrigations produced the same root canal cleanliness; however, nano-chitosan final irrigation solution generated the longest sealer penetration and the greatest apical sealing ability than EDTA and NSC. (EEJ-2024-12-188).
在根管治疗中，根管最终冲洗对于去除玷污层，尤其是无机成分起着至关重要的作用，以实现根管系统的严密封闭。本研究旨在评估使用螯合剂（即纳米壳聚糖）进行最终冲洗后根管系统的根管清洁度、封闭剂渗透情况及根尖封闭能力，并与乙二胺四乙酸（EDTA）和新型柠檬酸银（NSC）进行比较。
本研究使用了135颗前磨牙，分为三项评估：根管清洁度、封闭剂渗透情况和根尖封闭能力。牙齿被分为三组。第1组：EDTA，第2组：NSC，第3组：纳米壳聚糖。使用扫描电子显微镜（SEM）评估根管清洁度和根尖封闭能力。利用体视显微镜评估封闭剂渗透情况。根管清洁度数据采用卡方检验进行分析，而封闭剂渗透情况和根尖封闭能力数据采用双向方差分析和LSD事后检验进行分析，显著性水平为95%。
在根管清洁度评估中，所有三种最终冲洗液显示出相似的根管清洁度（p>0.05）。在封闭剂渗透情况和根尖封闭能力评估中，与EDTA和NSC相比，纳米壳聚糖产生了最高的封闭剂渗透和根尖封闭能力（p<0.05）。
所有最终冲洗均产生相同的根管清洁度；然而，纳米壳聚糖最终冲洗液比EDTA和NSC产生了最长的封闭剂渗透和最大的根尖封闭能力。（EEJ - 2024 - 12 - 188）
