Effects of auxiliary device use on smear layer removal

Abstract: This study evaluated the effects of different auxiliary irrigation devices on smear layer removal with a chelating solution (QMix). Fifty single-rooted permanent human teeth were shaped with a sequence of nickel-titanium instruments. A 2% chlorhexidine gel was used as a chemical auxiliary substance during preparation. Samples were assigned to five groups (n = 10 each) according to final irrigation protocol, namely, distilled water (control group), QMix 1 min, QMix + passive ultrasonic irrigation (PUI), QMix + … Show more

“…Hence, the importance of the depth of irrigation needle should be at the working length to irrigate the apical third of the canal, which can be implemented in a clinical setting [ 45 ]. Moreover, when activation and agitation were added on QMix, it enhanced its smear layer removal ability and showed a significant difference compared to QMix without agitation [ 46 47 48 49 50 51 52 53 ].…”

“…Em relação aos condutos distais estudados, na análise considerou-se as substâncias químicas Hipoclorito de Sódio 2.5% e Clorexidina gel 2%, juntamente com os dispositivos de agitação Irrisonic, Easy Clean, e Escova intracanal, por meio de MEV. Outros estudos semelhantes também foram realizados, utilizando-se da mesma metodologia de análise e dentes humanos extraídos (CARON et al, 2010;MENDODNÇA et al, 2015;KATO et al, 2016;PRADO et al, 2016). As análises das imagens foram realizadas por 2 operadores cegos independes, experientes, e estabelecidos scores quanto a limpeza de paredes, remoção de smear layer e abertura dos túbulos dentinários, semelhantemente a trabalhos já descritos anteriormente (CARON et al, 2010;KATO et al, 2016;CHARLIE et al, 2018;ZANDI et al, 2019).…”

“…Para que as mesmas consigam alcançar estas áreas, é necessário, além da ampliação do canal radicular, por meio das limas endodônticas, , o uso de agulhas de pequeno calibre (GUTARTS et al, 2005) e dispositivos de agitação. Estes dispositivos, visam potencializar a ação dos irrigantes, para que estes entrem em contato com as paredes do canal radicular, principalmente nas áreas onde não ocorrem a ação dos instrumentos (PETERS et al, 2001;GUTARTS et al, 2005;PERÉZ et al, 2018;VERSIANI et al, 2018), auxiliando nesta etapa de descontaminação do sistema de canais radiculares (MENDODNÇA et al, 2015;PRADO et al, 2016).…”
