ؤomparison of apical sealing ability of endodontic sealers at different storage times
Abstract
the main object of this study is to test how well revelational sealers ( IRoot sealer, MTA sealer, and glass ionomer sealer) can seal the apical part of roots using a single cone obturation procedure with the dye withdrawal method Forty-five removed human mandibular premolar teeth with circular canals were decorated at a length of 13mm and instrumented with the Proteper rotary system up to apical file size F3 with 0.04 taper utilizing a crown down procedure. After that Three experimental groups (n=15) were arbitrarily chosen from prepared roots and obturated as a group (A) roots filled with I Root sealer and a single gutta-percha. Group(B) The roots were sealed with mineral tri aggregate (MTA) sealer and a single gutta-percha. Group(C) roots were sealed with a Glass ionomer (GIS) sealer and a single cone gutta-percha. methylene blue dye was used to assess the apical leakage and measured by a computerized spectrophotometer utilizing the dye removal procedure. measurements of the apical leakage were down at different times Interval., The data was evaluated utilizing the One Way ANOVA test.Result After evaluation periods, the results displayed that the groupA ( I_Root sealer) had the lowest mean of dye leakage. Group B (MTA sealer), on the other hand, demonstrated an intermediate level of leakage. Group C had the greatest amount of leakage (GI sealer) with significant differences from the previous two groups about the time there was no significant difference statically in the means of the two groups one and two weeks.Conclusion I_Root sealer improved its ability to decrease the leakage of the obturated roots in comparison to the two others sealer while Glassinomer sealer can’t improve apical protection to the root from leakage.
