After standardizing working length (WL) and preparing the glide path, coronal flaring was performed. The instrumentation phase was completed with ProFile rotary instruments up to size #35 LightSpeed LSX. Roots were split into halves: in one of them, a groove was pre- pared in the apical 6 mm. In the opposite one, 5 depressions were made (at 2, 4, 6, 8 and 10 mm). Irregularities were filled with AH Plus sealer and flowable gutta-percha. The Efficacy of sodium hypochlorite (NaOCl) and chloroform in removal of material and the effect of positive pressure (PP), passive ultrasonic irrigation (PUI) (one or three cycles) and paper points were analysed with the chi-square test.Results: Delivery by PP did not eliminate the obturator material from any artificial depression. Chloroform, when activated, demonstrated a significant linear trend in the amount of gutta-percha removed at all tested levels (P<\/jats:p>","DOI":"10.5152\/eej.2017.16033","type":"journal-article","created":{"date-parts":[[2017,4,24]],"date-time":"2017-04-24T07:06:57Z","timestamp":1493017617000},"page":"9","source":"Crossref","is-referenced-by-count":1,"title":["Efficacy of Different Irrigation Protocols for Removing Gutta- Percha and Sealer Remnants in Artificial Un-instrumented Areas"],"prefix":"10.65717","volume":"2","author":[{"given":"Antonio","family":"Garcia","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rocio","family":"Fernandez","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ana","family":"Arias","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cesar De","family":"Gregorio","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"55248","published-online":{"date-parts":[[2017,12,12]]},"container-title":["European Endodontic Journal"],"original-title":[],"link":[{"URL":"https:\/\/www.eurendodj.com\/index.php\/pub\/article\/download\/30\/30","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.eurendodj.com\/index.php\/pub\/article\/download\/30\/30","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,1,22]],"date-time":"2026-01-22T12:39:46Z","timestamp":1769085586000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.eurendodj.com\/index.php\/pub\/article\/view\/30"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,12,12]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2017,12,12]]}},"URL":"https:\/\/doi.org\/10.5152\/eej.2017.16033","relation":{},"ISSN":["2548-0839"],"issn-type":[{"value":"2548-0839","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017,12,12]]}}}
