This study evaluated in vitro effectiveness of 17% EDTA with and without ultrasonics on
smear layer removal. One hundred and five extracted premolars randomly divided into
seven groups were instrumented with different final irrigating protocols: group A (Sal3US),
saline for 3 minutes with ultrasonics; groups B (Na3) and C (Na3US), 1% sodium
hypochlorite for 3 minutes without and with ultrasonics, respectively; groups D (ED3) and E
(ED3US), 17% EDTA for 3 minutes without and with ultrasonics, respectively; and groups F …
