Abstract:   (1168 Views)
Background and Aim: Materials used for root filling include cold ceramics, gutta percha and endoseal MTA. In this study, our aim is to investigate and compare the marginal adaptation of channels filled with cold ceramic and gutta percha - endoseal MTA.
Materials and Methods: In this experimental laboratory study, 20 extracted human single-rooted teeth were used. After canal preparation, the teeth were divided into two equal groups including 10 teeth. In the first group, cold ceramics were prepared according to the manufacturer's instructions and compacted inside the channels. In the second group, they were filled with gutta-percha and endosyl sealer MTA by lateral compression method. After one week, cross-sectional incubation was performed on the samples at 3 mm and 6 mm end to obtain a thickness of 3 mm and the maximum gap in microns between the root and wall fillers in the cross section directly by electron microscopy. Material / dentin contact was measured by Pearson, Spearman, and t-test.
Results: The mean distance between root and tooth filling materials in the cold ceramic group was
4.96±2.87 microns and in the second group was 12.03 ± 5.22 microns, which was statistically significant (P = 0.001).
Conclusion: In root canal filling, the degree of edge alignment in teeth filled with cold ceramics is significantly lower than that of gutta percha and endothelial sealant MTA.
