To evaluate if the ultrasonic activation of sealer hinders the root canal retreatment.
Materials and methods
Thirty mandibular premolars were prepared using the ProTaper Universal system (Dentsply) until the instrument F3 (0.30/0.09). The canals were distributed into 2 groups (
n
= 15), according to the filling technique: NUact group - sealer without ultrasonic activation + gutta-percha cones and Uact group - sealer with ultrasonic activation + gutta-percha cones. The canals were re-instrumented with Largo burs, followed by the instrument R50 (0.50/0.05) of the Reciproc system. The time required to perform re-instrumentation was recorded (s). The roots were longitudinally cleaved, and the total area of root canal and remaining filling material were quantified (%). The ANOVA test was applied to the data and complemented by Student’s
t
test (

To evaluate if the ultrasonic activation of sealer hinders the root canal retreatment.
Materials and methods
Thirty mandibular premolars were prepared using the ProTaper Universal system (Dentsply) until the instrument F3 (0.30/0.09). The canals were distributed into 2 groups (
n
= 15), according to the filling technique: NUact group - sealer without ultrasonic activation + gutta-percha cones and Uact group - sealer with ultrasonic activation + gutta-percha cones. The canals were re-instrumented with Largo burs, followed by the instrument R50 (0.50/0.05) of the Reciproc system. The time required to perform re-instrumentation was recorded (s). The roots were longitudinally cleaved, and the total area of root canal and remaining filling material were quantified (%). The ANOVA test was applied to the data and complemented by Student’s
t
test (
P
< 0.05).
Results
Uact group had higher percentage of remaining filling material than NUact group (
P
< 0.05). When the root thirds were considered, there was statistically significant difference only for Uact group at the apical third (
P
< 0.05). There was no difference between groups regarding the time required to perform re-instrumentation (
P
> 0.05).
Conclusions
Ultrasonic activation of sealer leads to a higher percentage of remaining filling material attached to the root canal walls. However, it did not affect the retreatment time.
Clinical significance
Ultrasonic activation increases sealer penetration into dentinal tubules, improving its resistance to dislodgement. However, there is no scientific evidence to prove if ultrasonic activation of sealer hinders its removal when root canal retreatment is necessary.</description><identifier>ISSN: 1432-6981</identifier><identifier>EISSN: 1436-3771</identifier><identifier>DOI: 10.1007/s00784-020-03752-0</identifier><identifier>PMID: 33392803</identifier><language>eng</language><publisher>Berlin/Heidelberg: Springer Berlin Heidelberg</publisher><subject>Dentistry ; Endodontics ; Medicine ; Original Article ; Premolars ; Root canals ; Sealing compounds ; Statistical analysis ; Tubules</subject><ispartof>Clinical oral investigations, 2021-07, Vol.25 (7), p.4401-4406</ispartof><rights>The Author(s), under exclusive licence to Springer-Verlag GmbH, DE part of Springer Nature 2021</rights><rights>The Author(s), under exclusive licence to Springer-Verlag GmbH, DE part of Springer Nature 2021.</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c375t-54c03a2ac86c70425f5c2f7dde823854948db8fa09c4ccd5cb326e9d1cbe118f3</citedby><cites>FETCH-LOGICAL-c375t-54c03a2ac86c70425f5c2f7dde823854948db8fa09c4ccd5cb326e9d1cbe118f3</cites><orcidid>0000-0002-8724-0124</orcidid></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://link.springer.com/content/pdf/10.1007/s00784-020-03752-0$$EPDF$$P50$$Gspringer$$H</linktopdf><linktohtml>$$Uhttps://link.springer.com/10.1007/s00784-020-03752-0$$EHTML$$P50$$Gspringer$$H</linktohtml><link.rule.ids>314,776,780,27901,27902,41464,42533,51294</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/33392803$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>da Silva Machado, Ana Paula</creatorcontrib><creatorcontrib>Câncio Couto de Souza, Antônio Caetano</creatorcontrib><creatorcontrib>Lima Gonçalves, Tamille</creatorcontrib><creatorcontrib>Franco Marques, André Augusto</creatorcontrib><creatorcontrib>da Fonseca Roberti Garcia, Lucas</creatorcontrib><creatorcontrib>Antunes Bortoluzzi, Eduardo</creatorcontrib><creatorcontrib>Acris de Carvalho, Fredson Márcio</creatorcontrib><title>Does the ultrasonic activation of sealer hinder the root canal retreatment?</title><title>Clinical oral investigations</title><addtitle>Clin Oral Invest</addtitle><addtitle>Clin Oral Investig</addtitle><description>Objectives
