“…[20] In spite of using different methodologies and obturation techniques, the better sealing ability of GuttaFlow over AH Plus was supported by the finding of a previous study. [2122] However, Brackett et al . found that the sealing ability of GuttaFlow/gutta-percha using the single-cone technique and AH Plus/Gutta-percha using the warm vertical compaction or continuous wave technique was similar.…”

Aim:The aim of this study is to compare the corono-apical sealing ability of three single-cone obturation systems using a glucose leakage model.Materials and Methods:A total of 90 extracted maxillary single rooted teeth were selected and their crowns were cut. The root canal of each sample was instrumented using a rotary crown down technique and then divided into four experimental (n = 20 each) and two control groups (n = 5 each). Samples in the experimental groups were filled as follows: Group 1, cold lateral condensation using Gutta-percha/AH Plus; Group 2, single-cone Gutta-percha and AH Plus; Group 3, single-cone Gutta-percha/and GuttaFlow2; Group 4, single-cone Resilon/RealSeal SE after 7 days, the sealing ability of root canal fillings was tested at different time intervals using glucose leakage model. Glucose leakage values were measured using a spectrophotometer and statistically analyzed.Results:The four experimental groups presented significantly different glucose leakage values at all test periods (P < 0.05). At the end of the observation period, the cumulative glucose leakage values of Groups 3 and 4 were significantly lower than those of Groups 1 and 2 (P < 0.05).Conclusion:Gutta-percha/GuttaFlow2 or Resilon/RealSeal SE combinations provided the superior sealing ability over the lateral condensation technique.

“…Zinc and oxide and eugenol based sealers are still widely employed due to its low cost and acceptable physical/chemical and biological properties (4)(5), while AH Plus presents better behavior and has been recognized as a gold standard amongst endodontic sealers, considering its sealing capacity, physical/chemical and biological properties (5)(6). Among the silicone-based sealers, GuttaFlow was developed to enhance physical characteristics, such as porosity, flow and adhesion to the root canal walls (7)(8). It consists of a matrix of polydimethylsiloxane filled with gutta-percha powder and nanosilver particles (9)(10), having unique sealing properties due to its insolubility, expanding post-setting and excellent flow ability (9)(10)(11).…”

Satisfactory biological behavior is a necessary requirement for clinical application of endodontic materials. In this study, the connective tissue responses to silicone (GuttaFlow 2), epoxy resin (AH Plus) and zinc oxide and eugenol (Endofill) based sealers were compared. Twelve Wistar rats had polyethylene tubes (four per animal) containing one of the tested sealers and empty tubes (negative control) implanted in their subcutaneous tissue. The tubes were randomly placed 2 cm from the spine and at least 2 cm apart from one another. Tissue samples with implants were processed for histological analysis after 7 or 60 days (n=6 animals per period). Inflammatory cells, fibrous condensation and abscess were scored according to their intensity. Friedman, followed by Dunn's post hoc, was used to compare sealers. Differences between the two experimental periods were verified using Mann-Witney U test (p<0.05). At 7 days, most of the histological parameters showed no significant differences amongst groups. Endofill group scored higher than the others for giant cells (o<0.05) and promoted a greater number of samples presenting abscess formation. GuttaFlow 2 tended to show a less intense inflammatory infiltrate compared to the other materials. At 60 days, there were no significant differences between groups in most of the histological parameters evaluated. However, it was observed that Endofill scored higher for macrophages (p<0.05) compared to the control group, and GuttaFlow 2 tended to present lower scores than the others for neutrophils and abscess. GuttaFlow 2 showed proper biological behavior and should be considered adequate for clinical practice.

“…Este resultado refuerza la idea de que el empleo de un sellador endodóntico se hace necesario para favorecer el sellado del material de obturación radicular. Se ha reportado en estudios previos que, la gutapercha, al no adherirse a las paredes de la dentina, no es capaz de proveer un sellado satisfactorio 28 , hecho que también pudo comprobarse en nuestro estudio. Cuando se compararon los cementos ADSEAL TM y Viarden®, los resultados demostraron que el cemento a base de ZOE tuvo valores significativamente mayores de filtración (p<0.05).…”

The use of endodontic posts is indicated to help the retention of the final restoration, they are usually made of fiberglass and allow the tooth to recover its functionality. Before its placement, it is necessary to perform a three-dimensional sealing of the root canals, for this purpose, gutta-percha filling material and root canal sealers are used. There is evidence that the presence of eugenol in sealers affects the polymerization of resin cements, which in turns decrease the adhesion of the post. For this reason, the aim of this work was to compare the push-out strength, and additionally, the microfiltration and radiographic density of two root sealers in bovine teeth roots. Two commercially available endodontic root canal sealers were used: VIARDEN® (zinc oxide and eugenolbased sealer) and ADSEAL TM (epoxy resin-based sealer). Data was analyzed using a significance level of α = 0.05. The push-out bond strength test showed that the group sealed with ADSEAL™ sealer obtained the highest values; the microfiltration results showed that ZOE-based sealer had the highest values (p<0.05) and the radiographic density was statistically similar (p>0.05). From de analysis performed, it is concluded that the chemical composition of the material used as an endodontic sealer has a significant influence on the apical microfiltration and push-out bond strength. The epoxy resin-based sealer seems to have the best performance so it can be considered as ideal for endodontic procedures.
