An endodontic treatment consists in cleaning, shaping and filling the root canal system. Irrigation is the chemical part of the process that ensures the total removal of debris. Activating the irrigation solution will improve and accelerate the process.
The aim of the study is to evaluate the removal of debris and smear layer at 1, 3, and 5mm from the foramen after needle irrigation, EndoActivator® and Irrisafe®. Sixty single-rooted teeth were prepared using Primary WaveOne Gold®.
Teeth were randomly assigned to 4 groups (n=15): needle irrigation - Group A, EndoActivator® for 1 min - Group B, Irrisafe® for 1 min - Group C, Irrisafe® for 30 sec - Group D. Root canals were observed under a scanning electron microscope. Data were analyzed by Friedman and Wilcoxon tests.
Debris was significantly higher with group A compared to B, C, and D. Irrisafe® was significantly more effective in removing the smear layer than the other groups. However, activation techniques showed less debris and smear layer than needle alone nevertheless.
Irrisafe® showed the best results regardless of time.
根管治疗包括清洁、塑形和充填根管系统。冲洗是该过程的化学部分，可确保彻底清除碎屑。激活冲洗液将改善并加速这一过程。
本研究的目的是评估在使用针管冲洗、EndoActivator® 和 Irrisafe® 后，距根尖孔1、3和5毫米处碎屑和玷污层的清除情况。使用初代WaveOne Gold® 预备60颗单根牙。
将牙齿随机分为4组（每组n = 15）：针管冲洗 - A组、EndoActivator® 冲洗1分钟 - B组、Irrisafe® 冲洗1分钟 - C组、Irrisafe® 冲洗30秒 - D组。在扫描电子显微镜下观察根管。数据采用Friedman和Wilcoxon检验进行分析。
与B、C和D组相比，A组的碎屑明显更多。Irrisafe® 在去除玷污层方面比其他组显著更有效。然而，激活技术显示出的碎屑和玷污层仍比单独使用针管冲洗时少。
无论时间长短，Irrisafe® 均显示出最佳效果。
