“…Success of root canal treatment has been shown in the range between 53% and 94% [18,19]. In the present study, no difference in the clinical and radiographic status was observed in teeth filled using TF as compared to LC after 12 months of observation.…”

“…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 .…”

“…Various bacteria have been used in microleakage studies [17][18]21,25 . However, there is a focus on E. faecalis because of its resistance [19][20]22,24 , survival in nutrient-poor areas over long periods 26 , and association with persistent chronic periapical lesions 27 . The results demonstrated that the mean time of leakage in samples in the experimental period was 21 days.…”

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.

“…In the single cone technique on the other hand, the same effective apical compaction is attributed to the tapered gutta-percha cones. Although the literature on apical leakage in relation to lateral compaction and the single cone technique reports similar results, like those of Pérez Heredia et al (9) and Gordon et al (8), Yücel anḑ Ciftçi (22) have also argued that the single cone technique creates more leakage than the lateral compaction technique.…”

The purpose of this study was to compare the sealing ability of different tapered gutta percha cones that were used with lateral compaction and single cones in canals prepared with various root canal instruments. One hundred extracted maxillary incisor roots were used. In group 1, 30 roots were prepared with stainless steel instruments (SS) and then filled by the lateral compaction technique using .02 tapered master cones. In group 2, 30 roots were prepared with ProFile ® nickel titanium instruments (NiTi) and filled in the same way as group 1. In group 3, 30 roots were filled by the single cone technique using 0.06 tapered guttapercha cones. The remaining 10 teeth were taken as two control groups. Apical and coronal leakage was evaluated using the fluid filtration model. Considering the effects of the instrumentation, no statistically significant differences were found between the groups prepared with SS and NiTi (P > 0.05). When the effects of obturation technique were taken into consideration, the ProFile ® instruments and lateral compaction resulted in significantly less coronal leakage than the SS instruments and lateral compaction (P < 0.05). There were no significant differences in apical leakage among any of the groups (P > 0.05).
