Evaluation of marginal adaptation by micro-CT
After seven days of filling the root-end cavities, the samples were scanned again to measure the volumes of empty spaces at the cement/dentin wall interface and inside the cement. The measurement method and parameters used were performed as described above.

Statistical Analysis

The Shapiro-Wilk test was used to verify data distribution. As normal distribution was observed, one-way ANOVA and Tukey’s post-hoc tests were used with a significance of 5%.
