Efficacy of different irrigant activation techniques for cleaning root canal anastomosis

BMC Oral Health

Table 2 Descriptive statistics of anastomosis cleanliness difference (Cleanliness percentage after final irrigation and activation– Cleanliness percentage after instrumentation.) comparing different activation methods at different levels (2 mm, 4 mm, and 6 mm) and as a total (average of the 3 levels). Data represented as mean ± SE (standard error). Differences were assessed by one-way ANOVA and Duncan post hoc tests at p < 0.05

Means with different letters indicate significant difference. Small letter is for the comparison between different activation groups, while capital letters are for the comparison between different levels in the same group
^* significant at p < 0.05, ns; non-significant at p > 0.05 (NA: Final Needle Irrigation)
