AGUILAR GUTIERREZ, Erika  y  GARCIA ARANDA, Raúl Luis. In vitro comparative study to meassure microleakage in obturation with pro root^®, CPM^®y Super EBA^®. Rev. Odont. Mex [online]. 2007, vol.11, n.3, pp.140-144. ISSN 1870-199X.  https://doi.org/10.22201/fo.1870199xp.2007.11.3.15812.

The purpose of this study was to evaluate the microleakage of four root-end filling materials. Forty-two single canal root extracted human teeth were cleaned and shaped. Each tooth was apically resected and the apex was prepared ultrasonically. The teeth were divided into 4 groups of 10 roots each and filled with PRO ROOT®, Super-EBA®, CPM® MEDIX and CPM® EGEO. Positive and negative controls were used. Apical leakage was determined using ink. The teeth were demineralized and transparent and the amount of dye microleakage was measured using a stereoscopic microscope at 20X magnification. Statistical analysis showed that Super-EBA®, CPM® EGEO and PRO ROOT® leaked significantly less than CPM® MEDIX.

Palabras llave : Microleakage; root-end fillings.
