“…This finding was consistent with Tasdemir et al [25] who found that filling with single-cone, lateral condensation, and warm vertical compaction techniques in canals treated with ProTaper or M two rotary instruments had similar levels of sealing efficacy.…”

“…Various methods have been employed in the evaluation of the obturation of root canals: dye leakage [12][13] , fluid filtration [14][15][16] , and bacterial leakage [17][18][19][20][21][22][23][24] . The option for bacterial leakage is justified since it is an experimental model that is simple and easy to replicate.…”

“…Most studies have used single-rooted teeth [17][18][19][20][21][22][23][24] . The use of molars was proposed due to their high incidence in endodontic treatment, and the choice of the distobuccal root of the maxillary molar was based on a standardization criterion 9 .…”

Aim: To compare bacterial leakage in root canals obturated with the modified single-cone, lateral condensation, and continuous wave of condensation techniques. Methods: Distobuccal root canals of maxillary molars were shaped up to ProTaper F2 and obturated with modified singlecone, lateral condensation or continuous wave of condensation technique. Two-chamber bacterial model using Enterococcus faecalis was employed for bacterial leakage evaluation for 30 days. The chi-square test was applied to evaluate differences between turbid and non-turbid samples, and the Kruskal-Wallis test was used for evaluating the time necessary for microleakage. A significance level of 5% was set for all analyses. Results: The modified single-cone technique showed leakage in 73.3% of samples, lateral condensation in 66.6%, and continuous wave of condensation in 53.3%, but there were no significant differences among the groups (p>0.05). Conclusions: It can be concluded that the modified single-cone technique shows similar sealing efficacy to that of lateral condensation and continuous wave of condensation technique.

“…A great number of endodontic filling materials, in combination with different filling techniques, have been suggested every year to replace the technique of cold lateral condensation. This technique has been regarded as having some disadvantages such as lack of homogeneity of the gutta-percha mass, a high percentage of sealer in the apical portion of the canal and poor adaptation to the root canals walls [3]. Moreover, the strength required to manipulate the spreader may increase the risk of dentinal damage and vertical root fracture [4].…”

“…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. The use of tapered cones with sealer could result in better adaptation to the root canal walls, without the requirement for accessory cones, being quicker than cold lateral condensation [3]. Therefore, the amount of sealer should be kept to a minimum, with only a thin layer between guttapercha and the wall of the canal.…”

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...
