Abstract
Background Endodontic therapy is conducted by replacing a neutral substance in the pulp space of the tooth to prevent the root canal. Mineral trioxide aggregate (MTA) and cold ceramic (CC) have been used in recent studies. Here, we aimed to investigate and compare the sealing power of CC and MTA over time. Methods In this experimental study, 100 single canal teeth from humans were used. The crowns of all teeth were cut by milling at the junction between the enamel and cement. Canal preparation was performed up to a final file size of 45. The samples were divided into 4 groups: MTA, cold ceramic, negative control and positive control. The samples were immersed in 2% methylene blue solution for 3 days, and the data were analyzed by statistical methods. Results There was no significant difference in dye penetration between the two cold ceramic materials and MTA at either time point (pv < 0.05). Conclusions The apical seal capabilities of both the cold ceramic root filler and MTA were not different, although further studies are needed due to the novelty of the cold ceramic.
