“…The quality of root canal fillings is generally evaluated using two-dimensional radiographs, 19 leakage models, 1,5 and cross-sectional methods. 3,12 These techniques enable visualization of the distribution of root filling materials, such as gutta-percha and sealer, inside the canal.…”

“…29 Overall, in the present study, better results were observed with thermoplastic filling techniques, but the lateral-compaction bond strength values obtained were in accordance with previous studies which confirmed their clinical acceptability. 5,10,30 Therefore, clinical implications of filling techniques and/or endodontic sealers should not be based on bond strength results alone; assessment of the sealing ability using different infiltration methods as well as 3-D micro-CT evaluations could provide different perspectives and demonstrate the actual effects of the materials/techniques used for endodontic treatment.…”

“…1,2,3,4 According to De-Deus et al 5 and Gulsahi et al, 6 the material should completely fill the root canal, and the ideal outcome is a high volume of core material, generally gutta-percha, and a small quantity of sealer, to prevent growth of residual bacteria and inhibit introduction of new bacteria.…”

This study evaluates the effect of two thermoplastic obturation systems (MicroSeal and Obtura II) on bond strength of different sealers to intraradicular dentin. Sixty root canals of human canines were prepared using ProTaper rotary files (crown-down technique) and irrigated with 2.5% sodium hypochlorite and 17% EDTA. The root canals were filled by MicroSeal, Obtura II, or lateral compaction techniques using AH Plus and Epiphany SE. 1.5 mm thick root slices were subjected to the push-out test. ANOVA and Tukey's test showed that the bond strength values (MPa) observed in the groups obturated with MicroSeal (2.96 ± 2.72) and Obtura II (2.68 ± 2.18) did not significantly differ from each other (p > 0.05) but were significantly higher than that observed in the group obturated with lateral condensation (2.01 ± 1.48; p < 0.05). There were no statistically significant differences in strength (p > 0.05) among the root canal thirds (cervical: 2.44 ± 2.03; middle: 2.50 ± 2.27; and apical: 2.70 ± 2.34). Adhesive failures were predominant (60%) in all groups. In conclusion, MicroSeal and Obtura II techniques, using AH plus sealer, increased the resistance to displacement of the filling material, when compared with lateral compaction. Moreover, when used with Epiphany SE, these obturation systems did not affect the bond strength of the material to root dentin.

“…Bucco-lingual and mesio-distal radiographic projections were used to select teeth with single oval-shaped canal, that is, a long:short diameter ratio of the canal ≥2.5:1 at 5 mm from the apex. 20 The teeth with straight roots, mature root apex and similar anatomical characteristics were selected for this study. After access cavity, the canal patency was established with a size 10 K-type file (Dentsply Maillefer, Ballaigues, Switzerland).…”

Objective: to evaluate the efficacy of Reciproc System, with or without solvent for endodontic filling removal from oval shaped root canals. The time required for gutta-percha removal and the instrument fracture were also evaluated. Material and Methods: forty straight single-rooted premolars were prepared up to a size 30 and filled with gutta-percha and sealer, then randomly assigned to two retreatment groups (n = 20), treated with Reciproc System with or without chloroform (RS+C and RS). For all roots, procedural errors, time of retreatment and apically extruded material were recorded. After retreatment, roots were split longitudinally and then photographed. All images were evaluated with Image Tool software to calculate the percentage of residual material. Kolmogorov Smirnov and t tests were used to determine significant differences at P < .05. Results: no treatment completely removed the root filling material from the root canals. Analysis of the total area did not reveal statistical differences between the two groups (P >.05). Both groups also showed similar results in all tested thirds, with no statistical differences (P >.05). RS without solvent was faster in filling material removal than RS+C (P <.05). For both groups, none of the instruments showed intracanal fracture or visible signs of plastic deformation. Conclusion: taken together, our results demonstrated that Reciproc System used without solvent required less time to remove the same amount of root filling material than Reciproc System with solvent. However, regardless of solvent use, the same cleaning quality was obtained.

ÖzetAmaç: Bu çalışmanın amacı, alt kesici dişlerin kök kanallarına uygulanan farklı kök kanal dolum yöntemlerinin güta-perka (GP), kanal patı doluluğu ve kalan boşluk açısından karşılaştırılmasıdır. Yöntem: 60 adet alt kesici dişin kök kanalları ProTaper Universal NiTi döner eğe sistemi ile F2 nolu eğeye kadar genişletildi. Dişler rastlantısal olarak 3 farklı kanal dolum grubuna ayrıldı (n=20). Genişletilen kök kanalları soğuk lateral kompaksiyon, ProTaper F2 tek kon tekniği ve sıcak vertikal kompaksiyon yöntemleri ile MTA Fillapex (Angelus Solucoes Odontologicas, Londrina PR, Brezilya) kanal patı kullanılarak dolduruldu. Daha sonra dişlerden apikal üçte bir bölgeden 2, 4, 6, 8 mm uzaklıklardan yatay kesitler alındı. Her kesitteki alanlar ölçüldü ve toplam alana göre GP, kanal patı ve boşluk yüzdeleri hesaplandı. Bulgular: 2 mm haricindeki diğer kesitlerde gruplar arasında boşluk açısından bir fark izlenmedi (P > 0.05). Sıcak vertikal kompaksiyon tekniğinde en fazla GP ve en az kanal patı dolu alan izlendi (P < 0.05). Soğuk lateral kondensasyon tekniğinde ise en az GP ve en çok kanal patı dolu alan izlendi (P < 0.05). Sonuç: Alt kesici dişlerin kök kanal dolgusunda soğuk lateral kondensasyon tekniğinde en az, sıcak vertikal kompaskiyon tekniğinde ise en fazla GP dolu alan olduğu görülmüştür.
