Introduction Apical seal is an important factor in successful root canal therapy. Still there are controvercies about sealing ability of various sealers materials. Recently Roth-Sealer which is very popular in Europe and U.S.A has been produced by an Iranian company. The purpose of this study was to compare sealing ability of Iranian Roth Sealer with ZOE, Tubli-Seal and AH26. Materials &amp; Methods In this study we used 100 fresh extracted single root teeth of human. After cutting the crown from CEJ and determination of working length, canal preparation was done with passive step back technique using patency file. The teeth randomly were divided into 6 groups. Four groups with 20 teeth for experimental groups and two groups with 10 teeth as positive and negative control groups . Obturation was done with lateral condensation in four groups with Roth Sealer, ZOE, tubli-Seal and AH26. The coronal seal was achieved with amalgam. In positive control group, we didn't use sealer.After preparation all teeth were incubated at 37 oc temperature and 100 humidity for 72 hours. All teeth were covered with two coats of nail polish and sticky wax except 2mm of apical part. In the group of negative control, all of the tooth surface were covered. Dye penetration was measured using Indian ink (PH=6.2). After spliting the teeth longitudinally, dye penetration was measured by steriomicroscope. Data were analyzed with ANOVA and DUNCAN tests. Results Results showed that dye penetration in positive control group was complete and significantly more than other groups while in negative control group , no dye penetration was observed and in Roth Sealer group , it was significantly less than other groups(P<0.05). There was no significant difference between ZOE, Tubli Seal and AH26. Conclusion Iranian Roth sealer proved to be appropriate for root canal therapy compared to other 3 sealers. So, this can be considered as a substitute for foreign Roth sealer which is very expensive. Performing histologic studies on it for confirmation is recommended.
