Comparative analysis of two root sealers based on ZOE and epoxy resin
Abstract
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 eugenol-based sealer) and ADSEALTM (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.
