Comparative analysis in vitro of coronal leakage in root canals filled with two different endodontic sealers.

Abstract

This study objectified to analyze, in vitro, the sealing propery of two endodontic sealers, Endofill® and Sealapex®, as coronal leakage along the root canal. Thirty single-rooted teeth were divided into two groups in accordance with the filling material. The teeth were prepared, obturated by lateral condensation technique with gutta-percha and one of the sealers and sealed with temporary restorative material Cimpat®. After, the teeth were placed in an oven at 37°C and 100% humidity where they remained for seven days. Them the roots sealed with nail polish and were placed in another container containing the dye marker Silver Nitrate 50%, remaining at 37ºC for ten days. After this period, the crowns were removed and the roots were transversely sectioned into three thirds: the cervical, middle and apical. An analysis was made of the cuts and the data were subjected to Fischer's exact test, which showed statistical difference between the experimental groups, and the Endofill® allowed a greater degree of infiltration.
