- Means ± standard deviations and medians (interquartile ranges), the latter in the second lines
- Scores were ranging from 1 (residual stain >95%) to 6 (residual stain <5%)
-
TT Tip of the threads, AT Apically facing thread surfaces, BT Area between threads, M Machined surface area, R Rough shoulder area
- Different capitals indicate groups with statistically significant differences (p < 0.001 for all comparisons except M vs. R where p = 0.01), as assessed by pairwise Wilcoxon-rank-sum-tests with p-value adjustments for multiple comparisons according to Holm
