“…Baumgartner & Cuenin [37] also observed that ultrasonically energized NaOCl, even in higher concentrations such as 5.25%, did not remove smear layer from the root canal walls. Although the ability of PUI to remove the smear layer has been reported previously [38,25], our results showed that PUI was not superior to the XP-Endo finisher file under similar experimental conditions. This is in agreement with other studies [39,40], which have demonstrated that PUI did not completely remove smear layers from the apical third of canal walls.…”

Objectives: The purpose of this study was to evaluate the effectiveness of two different final irrigant activation methods in removing the smear layer at 3 and 7 mm from the apex.Methods: Thirty-six extracted single-rooted human mandibular premolars were instrumented by a reciprocating Wave-One 40.08 (Dentsply Maillefer, Switzerland) and irrigated with 2.5ml. 2.5% NaOCl at 37 C°. Teeth were divided into four groups according to the final irrigant activation technique (Group 1: XP-Endo Finisher File NaOCl 2.5% /EDTA 17%; Group 2: XP-Endo Finisher File NaOCl 2.5%; Group 3: passive ultrasonic irrigation [PUI] NaOCl 2.5% /EDTA 17% and Group 4: PUI-NaOCl 2.5%). Root canals were then split longitudinally and observed by field emission scanning electron microscopy. The percentage of area of open dentinal tubules was evaluated. Data were analyzed using the Kolmogorov-Smirnov and two factor ANOVA.Results: In all groups, the middle third of the roots demonstrated a significant higher percentage of dentinal tubules free of smear layer compared to the apical third (p<0.05). The XP Endo-finisher NaOCl/EDTA group showed a higher percentage of open dentinal tubules for the middle and apical thirds (P < 0.001). Group 3 (PUI NaOCl/EDTA) removed more smear layer at both root thirds than groups 2 (XP Endo-finisher NaOCl) and 4 (PUI NaOCl) respectively (p<0.001).Conclusions: None of the systems eliminated the smear layer; nevertheless, the XP-Endo-finisher NaOCl/EDTA group was more effective than PUI with and without EDTA for smear layer removal at both middle and apical canal thirds.Clinical significance: The use of the XP-Endo-finisher file system is an effective method for smear layer removal after root canal instrumentation.

“…Guerisoli et al 57 (2002) propuseram a utilização do ultrassom para agitar as soluções e verificaram que a ação dos quelantes foi efetivada quando em maior contato com as superfícies dentinárias, através do carreamento do EDTA conduzido pelo ultrassom. O mesmo foi encontrado, em um estudo comparando a eficácia de diferentes soluções irrigadoras quando da irrigação clássica com seringa e irrigação passiva ultrassô-nica (PUI).…”

A eficácia da solução de EDTA na remoção de smear layer e sua relação com o tempo de uso: uma revisão integrativa IntroduçãoO sucesso do tratamento endodôntico está intimamente relacionado à qualidade da limpeza e desinfecção do sistema de canais radiculares (SCR), obtido por meio da eliminação ou pelo menos redução do conteúdo orgânico e inorgânico contaminado do interior dos canais 1,2 . Para atingir tais objetivos, os canais são submetidos ao preparo químico mecâ-nico (PQM).O PQM é considerado um requisito chave para o sucesso da terapia endodôntica, uma vez que consiste na limpeza e modelagem -clean and shape-do

“…5 Removal of the smear layer can be considered an essential step in successful root canal treatment. 17 For this reason, the smear layer was removed in this study before evaluation of the penetration and adaptation of root canal filling materials. The quality of the filling depends largely on the sealing ability of the sealers.…”

Background and objectives:The purpose of this study was to evaluate the effect of two sealers on coronal seal and the coronal sealing ability of two obturation techniques. Methods: Forty extracted single-rooted human teeth were instrumented with the stepback technique and were irrigated with 5.25% sodium hypochlorite (NaOCl). The smear layer was removed by washing with 10 ml of 17% ethylene diamine tetra-acetic acid (EDTA) and 10 ml of 5.25% (NaOCl). All instrumented root canals were randomly divided into two experimental groups; Group A: 20 roots epoxy resin sealer (AH26) was used, Group B: 20 roots Zinc oxide euginol (ZOE) sealer was used. Each group of main groups were subdivided randomly into two obturation groups; 1. 10 roots obturated by thermo plasticized technique (obtura II), 2. 10 roots obturated by cold lateral compaction technique. The root surfaces were then coated with nail polish except for the coronal, then dye penetration study was conducted and samples were examined under the stereomicroscope. Data had been collected from three independent examiners and statistically analyzed using student t-test. Results: There were significant differences between AH26 with ZOE in group obturated by obtura II and when obtura II technique compared with the cold lateral compaction technique in group of AH26 sealer. Conclusion: Epoxy resin sealer (AH26) and obtura II gave the best results in coronal sealing when compared with Zinc oxide euginol sealer and cold lateral compaction technique.

Evaluation of smear layer removal by EDTAC and sodium hypochlorite with ultrasonic agitation

Abstract: Under ultrasonic agitation, sodium hypochlorite associated with EDTAC removed the smear layer from root canal walls, whereas irrigation with distilled water or 1.0% sodium hypochlorite alone did not remove smear layer.
