Enhancing the Intracanal Antibacterial Effects of Sodium Hypochlorite with Etidronic Acid or Citric Acid
This study evaluated the bacterial reduction promoted by root canal preparation using irrigation with sodium hypochlorite (NaOCl) alone, associated with etidronic acid (1-hydroxyethane 1,1-diphosphonic acid [HEDP]) or alternated with citric acid, and after a supplementary agitation step.

| description | This study evaluated the bacterial reduction promoted by root canal preparation using irrigation with sodium hypochlorite (NaOCl) alone, associated with etidronic acid (1-hydroxyethane 1,1-diphosphonic acid [HEDP]) or alternated with citric acid, and after a supplementary agitation step.
Extracted mandibular premolars were selected and distributed into 3 groups based on anatomically paired micro–computed tomographic analyses. The canals were contaminated with Enterococcus faecalis for 30 days and then subjected to chemomechanical preparation with a reciprocating instrument under irrigation with NaOCl alone, mixed with HEDP (NaOCl/HEDP), or alternated with citric acid (NaOCl/CA). A supplementary agitation step with the XP-endo Finisher was performed in all groups. Intracanal bacteriological samples were taken before (S1) and after preparation (S2) and after the supplementary approach (S3). DNA was extracted from the samples and subjected to quantitative real-time polymerase chain reaction.
Intragroup analyses revealed a substantial bacterial reduction from S1 to S2 or S3 in all groups (P |

Intragroup analyses revealed a substantial bacterial reduction from S1 to S2 or S3 in all groups (P < .01). The supplementary agitation resulted in S2-to-S3 bacterial reduction of 6%, 68%, and 80% in the NaOCl, NaOCl/HEDP, and NaOCl/CA groups, respectively. Irrigation with NaOCl alone resulted in 53% and 47% of samples negative for bacteria in S2 and S3, respectively. Corresponding figures for NaOCl/HEDP were 75% and 85%, and 44% and 72% for NaOCl/CA. Intergroup analyses of S2 samples showed that NaOCl/HEDP was significantly more effective than the other 2 in reducing the bacterial levels (P < .05). After the supplementary approach, both NaOCl/HEDP and NaOCl/CA were significantly more effective than NaOCl alone (P < .05), with no significant differences between them (P > .05).
Both the freshly combined NaOCl/HEDP solution and the alternate use of NaOCl and citric acid followed by XP-endo Finisher agitation resulted in significantly higher intracanal bacterial reduction than NaOCl alone.</description><identifier>ISSN: 0099-2399</identifier><identifier>EISSN: 1878-3554</identifier><identifier>DOI: 10.1016/j.joen.2022.06.006</identifier><language>eng</language><publisher>Elsevier Inc</publisher><subject>Bacterial reduction ; citric acid ; endodontic treatment ; etidronic acid ; root canal irrigation ; root canal preparation ; sodium hypochlorite</subject><ispartof>Journal of endodontics, 2022-09, Vol.48 (9), p.1161-1168</ispartof><rights>2022 American Association of Endodontists</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c333t-c2ae450d6095f6f108538684cea8e0104c16524be04bb131832c3264b8a0707f3</citedby><cites>FETCH-LOGICAL-c333t-c2ae450d6095f6f108538684cea8e0104c16524be04bb131832c3264b8a0707f3</cites><orcidid>0000-0002-9922-8202</orcidid></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktohtml>$$Uhttps://www.sciencedirect.com/science/article/pii/S0099239922004149$$EHTML$$P50$$Gelsevier$$H</linktohtml><link.rule.ids>314,776,780,3537,27901,27902,65306</link.rule.ids></links><search><creatorcontrib>Campello, Andrea F.</creatorcontrib><creatorcontrib>Rodrigues, Renata C.V.</creatorcontrib><creatorcontrib>Alves, Flávio R.F.</creatorcontrib><creatorcontrib>Miranda, Karla R.</creatorcontrib><creatorcontrib>Brum, Sileno C.</creatorcontrib><creatorcontrib>Mdala, Ibrahimu</creatorcontrib><creatorcontrib>Siqueira, José F.</creatorcontrib><creatorcontrib>Rôças, Isabela N.</creatorcontrib><title>Enhancing the Intracanal Antibacterial Effects of Sodium Hypochlorite with Etidronic Acid or Citric Acid</title><title>Journal of endodontics</title><description>This study evaluated the bacterial reduction promoted by root canal preparation using irrigation with sodium hypochlorite (NaOCl) alone, associated with etidronic acid (1-hydroxyethane 1,1-diphosphonic acid [HEDP]) or alternated with citric acid, and after a supplementary agitation step.
