客观的。本研究的目的是通过评估根管清洁度和侧根管/副根管的堵塞情况来比较两种灌溉技术。研究设计。七十五颗拔出的尖牙被安装成#40/0.06 锥度尺寸。将 EndoActivator (EA) 与最终冲洗的超声波装置进行比较。每个单元使用 6.15% NaOCl 和 17% EDTA 各 1 分钟。对照组接受注射器冲洗。将三十颗牙齿切片并用扫描电子显微镜评估距根尖孔 3/5 毫米处的碎屑清除和开放牙本质小管。检查了四十五颗牙齿的侧牙根管堵塞情况。结果。与其他治疗组相比，EA 在清除各个级别的碎片方面均显着更好 (P < .05)，并导致更多数量的侧根管闭塞 (P < .01)。结论。 EA 可以更好地封闭侧根管和副根管，并减少残留碎片。 （口腔外科、口腔医学、口腔病理、口腔放射学 Endod 2011；112：809-813）
Objective. The purpose of this study was to compare 2 irrigation techniques by evaluating canal cleanliness and obturation of lateral/accessory canals.Study design. Seventy-five extracted canines were instrumented to a size #40/0.06 taper. The EndoActivator (EA) was compared with an ultrasonic unit for final irrigation. Each unit was used for 1 minute each with 6.15% NaOCl and 17% EDTA. A control group received syringe irrigation. Thirty teeth were sectioned and evaluated for debris removal and open dentinal tubules at 3/5 mm from the apical foramen with a scanning electron microscope. Forty-five teeth were examined for obturation of lateral canals.Results. The EA was significantly better in removing debris at all levels when compared with other treatment groups (P < .05) and resulted in obturation of significantly more numbers of lateral canals (P < .01.)Conclusions. The EA provided better obturation of lateral and accessory canals and resulted in less remaining debris. (Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2011;112:809-813)
