Effects of using Endoactivator® for final irrigation on debris and smear layer scores: an sem comparison.
J Pak Dent Assoc Jan ;19(2):087-90.

OBJECTIVE: To evaluate the effectiveness of the EndoActivator® on smear layer adhered to the root canal surface. METHODOLOGY: 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. RESULT: The level of significance was set at P = 0.05. The EndoAetivator® group differed significantly from the non-activated group (P < 0.05). However, there was no statistically significant difference (P > 0.05) between the EndoActivato1'® group and the Canal Finder group or between the non-activated group and the Canal Finder gr0up.. CONCLUSION: 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.
