Comparison of the cleaning efficacy of EndoVac with conventional irrigation needles in debris removal from root canal. An in-vivo study

摘要

Aim and Objective:The aims were to evaluate the root canal debris removal after irrigation with EndoVac system and to compare its efficacy with Max-i-Probe needles.Materials and Methods:Fifteen matched pairs of single canalled vital teeth with mature apices indicated for extraction were selected. After working length determination and biomechanical preparation, the teeth in the right quadrant were irrigated with EndoVac system and with Max-i-Probe needles in the left quadrant using 3% NaOCl and 17% ethylenediaminetetraacetic acid. Teeth were extracted and marked at 1 and 3 mm from working length and decalcified in Kristenson's solution. Stained histologic slides were observed under trinocular research microscope. Wilcoxon signed-rank test was used for statistical analysis. The statistical significance was set at P < 0.05 and the analysis was performed using SPSS version 11.0 software.Results:No statistical significant difference was found at 3 mm level between the groups. Group I had significantly less debris at 1 mm level.Conclusion:EndoVac performed better in removing debris from the apical thirds of root canals.
