“…The model used in this study was based on a model previously described [5]. Briefly, the tapered ends of 1.5 mL polypropylene centrifuge tubes (Axygen Scientific, Union City, CA, USA) were cut and the obturated root was inserted with the apex pointing down.…”

“…Alternative techniques allowing better adaptation to canal walls and a higher degree of homogeneity have been suggested [5,6]. The single cone technique (SC) consists of selecting a single gutta-percha cone matching the exact size and conicity of canals prepared with rotary instruments.…”

“…No statistical difference in quality of root canal obturation with Resilon/Epiphany, SC, warm lateral condensation and System B was observed for some studies [5,11,12]. However, another study revealed significant difference between AH Plus, Resilon/ Epiphany, and Gutta-percha [13].…”

Objective: To evaluate and compare, by means of bacterial infiltration, the quality of sealing obtained by Tagger's hybrid (TH) and Single Cone (SC) techniques, in association with AH Plus/Gutta-percha (AH) and Epiphany/Resilon (ER). Methods: Palatal roots of 70 maxillary molars were instrumented and divided randomly into six groups: G1, TH/AH; G2, SC/AH; G3, TH/ER; G4, SC/ER; G5, negative control; G6, positive control. The roots were sterilized and monitored for 56 days to detect bacterial leakage using Enterococcus faecalis. The data were subjected to Binomial test (α<0.05) to compare the infiltration among groups and Kruskal-Wallis test (α<0.05) to analyze the infiltration as a function of time.Results: All positive controls leaked within 24 h; none of negative controls leaked. There was no influence of time on leakage. Individual comparisons showed that there were no influences of the techniques and filling materials on quality of root canal sealing. Significant difference was found only between G1 and G4 (p=0.0229), the G1 showed a lesser and G2 the higher quantity of infiltration. Conclusion: It could be concluded that none of the groups was able to prevent bacterial leakage and the lowest ability to prevent infiltration was obtained when applied SC/ER to filling the canal.Key words: Bacteria; Dental materials; Endodontic; Root canal obturation; Dental leakage.Comparação da infiltração bacteriana entre os cimentos Epiphany e AH Plus usando as técnicas de obturação de cone único e Híbrida de Tagger Resumo Objetivo: Avaliar e comparar, por meio da infiltração bacteriana, a qualidade de selamento obtido pelas técnicas híbrida de Tagger (TH) e do cone único (SC) associadas com AH Plus/Guta-percha (AH) e Epiphany/Resilon (ER) . Métodos: Raízes palatinas de 70 molares superiores foram instrumentadas e divididas aleatoriamente em seis grupos: G1, TH/AH; G2, SC/AH; G3, TH/ER; G4, SC/ER; G5, controle negativo; G6, controle positivo. As raízes foram esterilizadas e monitoradas durante 56 dias para detectar a infiltração bacteriana utilizando Enterococcus faecalis. Os dados foram submetidos a teste Binomial (α<0,05) ao comparar a infiltração entre grupos e Kruskal-Wallis (α<0,05) para analisar a infiltração, como uma função do tempo. Resultados: Todos os controles positivos infiltraram em 24 horas. Nenhum dos controles negativos infiltrou. Não houve influência do tempo na infiltração. Comparações individuais mostraram não haver influencia das técnicas e materiais de obturação na qualidade de selamento do canal radicular. Houve diferença significativa apenas entre G1 e G4 (P=0,0229), o G1 mostrou o menor e G4 a maior quantidade de infiltração. Conclusão: Nenhum dos grupos foi capaz de evitar a infiltração bacteriana e a menor capacidade de prevenir a infiltração foi obtida quando utilizados de SC/ER para obturar o canal.Palavras-chave: Bactérias, materiais dentários, endodontia, obturação do canal radicular, infiltração dentária. 88Rev Odonto Cienc 2014;29(3):87-91Assessment of bacterial leakage when using dif...

“…1,38,39 However, other investigations have indicated that some obturation systems like Guttaflow and Resilon cones with Epiphany provide better seal against microbial leakage than gutta-percha/AH-plus sealer. 40-43 , However, greater amount of microleakage has been reported with Resilon compared to gutta-percha/zinc oxide eugenol and AH-plus.…”
