The aim of this study was to compare smear layer removal at apical 1 mm level after final irrigation activation with an EndoVac system and Max-I probe.
Fifty freshly extracted maxillary central incisors were randomly divided into two groups after completing cleaning and shaping with ProTaper rotary files. In one group, final irrigation was performed with an EndoVac system while in the other group final irrigation was performed with a 30 gauge Max-I probe. 3% sodium hypochlorite and 17% ethylenediaminetetracetic acid were used as final irrigants in all teeth. After instrumentation and irrigation, the teeth were sectioned longitudinally into buccal and palatal halves and viewed under a scanning electron microscope for evaluation of the smear layer. Statistical analysis was performed using the Kruskal Wallis and Mann-Whitney U tests.
The EndoVac group showed significantly better smear layer removal compared with the Max-I probe at the apical 1 mm level.
An apical negative pressure system (EndoVac) results in better debridement at apical 1 mm when compared with side-vented closed ended needle irrigation (Max-I probe).
本研究旨在比较使用EndoVac系统和Max - I探针进行最终冲洗激活后，根尖1毫米处玷污层的去除情况。
50颗新鲜拔除的上颌中切牙在使用ProTaper旋转锉完成清理和成形后，随机分为两组。一组使用EndoVac系统进行最终冲洗，另一组使用30号Max - I探针进行最终冲洗。所有牙齿均使用3%次氯酸钠和17%乙二胺四乙酸作为最终冲洗液。在进行器械操作和冲洗后，将牙齿纵向切成颊侧和腭侧两半，置于扫描电子显微镜下观察玷污层，以进行评估。使用Kruskal Wallis检验和Mann - Whitney U检验进行统计分析。
在根尖1毫米处，EndoVac组的玷污层去除效果明显优于Max - I探针组。
与侧孔封闭式针头冲洗（Max - I探针）相比，根尖负压系统（EndoVac）在根尖1毫米处能实现更好的清创效果。
