Comparison of Apical Microleakage between Canals Filled with Gutta-percha/AH-26 and the Resilon/epiphany System by Dye Penetration Method

Majallah-i Dānishgāh-i ’Ulūm-i Pizishkī-i Shahīd Ṣadūqī Yazd, 2012
Introduction: Root canal obturation is a critical factor in success or failure of a root canal treatment. The material used for root canal obturation must be able to provide a perfect seal. This study aimed to compare the ability of gutta-percha/AH26 and
