To evaluate the effectiveness of the EndoActivator® on smear layer adhered to the root canal surface.
Sixty human single-rooted teeth were instrumented and divided in three groups. At the end of the instrumentation phase, each group was rinsed with 17% EDTA. One group was not activated and EDTA was left in situ for one minute. The second group was activated using EndoActivator®. The third group was activated with the Canal Finder System. Teeth were split longitudinally and both halves from each tooth were examined under SEM.
The level of significance was set at P = 0.05. The EndoActivator® group differed significantly from the non-activated group (P < 0.05). However, there was no statistically significant difference (P > 0.05) between the EndoActivator® group and the Canal Finder group or between the non-activated group and the Canal Finder group..
EndoActivator® was more effective in removing smear layer attached to root canal walls, although the differences compared to the Canal Finder System were not statistically significant.
