The purpose of this in vitro study was to evaluate the cleaning efficacy of NaviTip, Max-i-Probe and Endovac in removal of debris from the root canal at 1.5 and 3.5 mm from the apex.
Forty single-rooted teeth were divided into four groups according to the root canal irrigation system (EndoVac, NaviTip, Max-i-Probe, and control). Instrumentation was done using ProFile 0.06 taper series to MAF #40. Root canals were irrigated after each file size with 1 ml of 5% NaOCl. For final irrigation 5 ml of 5% NaOCl and 17% ethylenediaminetetraacetic acid (EDTA) was used. Each group was irrigated with a different irrigation device. Four micron thick serial sections were prepared at 1.5 and 3.5 mm from the apical level and photographs were taken for the analysis. The influence of the irrigation system was evaluated using a one-way analysis of variance (ANOVA) test and unpaired t-test (P < 0.05).
Endovac showed significantly least amount of mean percentage debris followed by Max-i-probe and NaviTip at both levels (P < 0.05). In all the experimental groups, significantly less amount of mean percentage debris was seen at 3.5 mm level than at 1.5 mm level (P < 0.05). However, the difference was statistically insignificant in case of Endovac irrigation system group.
Amongst all the experimental groups, Endovac removed significantly more debris followed by Max-i-probe and NaviTip at both levels.
本体外研究的目的是评估NaviTip、Max-i-Probe和Endovac在去除根尖1.5毫米和3.5毫米处根管内碎屑的清洁效果。
根据根管冲洗系统（EndoVac、NaviTip、Max-i-Probe和对照组）将40颗单根牙分为四组。使用ProFile 0.06锥度系列至MAF #40进行根管预备。每个锉号后用1毫升5%次氯酸钠冲洗根管。最后冲洗时使用5毫升5%次氯酸钠和17%乙二胺四乙酸（EDTA）。每组使用不同的冲洗装置进行冲洗。在距根尖水平1.5毫米和3.5毫米处制备4微米厚的连续切片，并拍照进行分析。使用单因素方差分析（ANOVA）检验和非配对t检验（P < 0.05）评估冲洗系统的影响。
在两个水平上，Endovac显示的平均碎屑百分比显著最少，其次是Max-i-probe和NaviTip（P < 0.05）。在所有实验组中，3.5毫米水平处的平均碎屑百分比明显低于1.5毫米水平处（P < 0.05）。然而，Endovac冲洗系统组的差异在统计学上不显著。
在所有实验组中，Endovac在两个水平上清除的碎屑明显更多，其次是Max-i-probe和NaviTip。
