Abstract　： [Abstract] The present study assessed the warm vertical obturation and evaluate the sealing ability of canals filled with resin-based sealer and gutta-percha Obtura IITM. The total of 72 plastic standard teeth (Dentsply-Maillefer, Switzerland) were used and divided into 2 group of 36 teeth. In group 1 root canals were filled with gutta-percha/ Epiphany (Pentron Japan) and in group 2 with gutta-percha /AH plus jet (Dentsply-Maillefer, Switzerland) sealer. The mean penetration of gutta-percha was measured until root apex by Olympus microscope SZXT16 with a digital camera DP71. The sealing ability of odturated was evaluated by dye leakage test. All canals were obturated, and the teeth were sectioned horizontally at 1, 3, and 5mm from the root apex. Sections were taken by a digital microscope,and quantified the proportion of core material in each canal. A one-way analysis of variance (ANOVA) and Scheffe testing were used to compared and identify any statistically significant differences at p<0.05. The result indicated that the both gutta-percha penetration was perfectly until root apex,and the sealing ability of both Epiphany and AH plus jet was significantly high in both groups. The proportion of the both gutta-percha was more than 83% at level of 1 mm, and more than 94% at level of 3 and 5 mm from apex. It was conclude that gutta-percha /Epiphany and gutta-percha / AH plus jet obturation were showed significantly less leakage with worm vertical obturation by Obtura II.
