Comparison of apical leakage of endodontic sealers AH Plus, Sealapex, Sealer 26 and Endofill through clearing teeth
Journal Title: RSBO - Year 2009, Vol 6, Issue 1
Abstract
Introduction and objective: The aim of this study was to analyze the infiltration of the sealers AH Plus®, Sealapex®, Sealer 26® and Endofill®,using clearing teeth technique. Material and methods: Fifty single-rooted teeth had its crowns removed and canals prepared by the Oregon modified technique. After the chemical-mechanical preparation, the root canals were filled with gutta-percha and four different sealers:group I: AH Plus®; group II: Sealapex®; group III: Sealer 26® and group IV: Endofill®. The others two groups of five teeth each served as positive and negative control groups. After filling, teeth remained for 60 days in saline solution 0.9%, simulating oral conditions.Following this stage, teeth were covered by three layers of nail polish, immersed in nankin ink and stored in a stove under 37ºC for 48 hours. After this period of time, the samples were washed in current water for 24 hours, the nail varnishes were removed with bistoury blade and the clearing technique was applied to evaluate the results. Results and conclusion:The results showed insignificant differences between the materials tested and so a similar behavior in the apical marginal infiltration.
