Abstract:

Purpose: The purpose of this study is to evaluate the Vibringe, EndoVac, passive ultrasound (PUI) and traditional spray irrigation (GSI) root channels of calcium hydroxide (CH) removal effects with the help of a scaned electron microscope (SEM). Tools and Methods: For this study, 70 single-root human mandibular premolar teeth were used. Examples were prepared to F4 with the ProTaper rotating system and filled with calcium hydroxide. A week later, calcium hydroxide was removed from the root channels using GSI (Group 1) , Vibringe (Group 2) , EndoVac (Group 3) and PUI (Group 4) methods.  During the processes, a total of six minutes (active and passive irrigation) for each sample was used 2.5 mL of 2.5 % NaOCI and then 2.5 mL of 17 % EDTA. The remaining amount of calcium hydroxide was divided into roots length to evaluate and examined in SEM under x50 and x1000 lengths. The data was statistically analyzed with Kruskal-Wallis and Mann-Whitney U tests (α = 0.05). Discovery: None of the methods used in the study could completely remove calcium hydroxide from the root channel walls. After GSI, there was a significant increase in calcium hydroxide in the channel walls, but there was no significant difference between Vibringe, EndoVac and PUI methods.(p> 0.05) However, in the GSI method, there was a significant increase in calcium hydroxide in the apical region, compared to the coronal and middle triangle. p = 0. The cleaning efficiency of the Vibringe, EndoVac and PUI methods did not differ significantly from the channel triple areas. The result: in the elimination of calcium hydroxide from the root channels, the Vibringe, EndoVac and PUI methods have shown similar cleaning efficiency, and these three techniques have been more successful than the GSI method.

Materials and Methods: Seventy single-rooted human mandibular premolar teeth were used for this study. The samples were prepared with the Protaper rotary system up to F4 and filled with calcium hydroxide. One week later, Calcium hydroxide was removed from the root channels with the several irrigation methods as follows: GSI (Group 1), Vibringe (Group 2), EndoVac (Group 3), PUI (Group 4).  During the irrigation procedure, for each sample, 2.5 mL of 2.5% NaOCl followed by 2.5 mL of 17% EDTA was used for six minutes totally (active and passive irrigation). For the evaluation of remaining calcium hydroxide, the roots were split longitudinally and evaluated under SEM at x50 and x1000. Data were analyzed statistically by Kruskal-Wallis and Mann-Whitney U tests (α=0.05). Results: None of the methods used in the study could completely remove the calcium hydroxide medication from the root canal walls. Although the most residual calcium hydroxide was observed on the canal walls after GSI irrigation, there was no significant difference between Vibringe, EndoVac and PUI methods (p> 0.05). However, the GSI method showed significantly more calcium hydroxide residues in the apical region (p=0.017) than the coronal and middle area. The cleaning efficiency of the Vibringe, EndoVac and PUI methods were not significantly different in root channel areas. Conclusions: In terms of calcium hydroxide removal from root channels, Vibringe, EndoVac and PUI methods were found to be more effective than the GSI; however, there was no significant difference could be detected between each other.
