“…Therefore, the use of a fibre post relined with a resin composite has been suggested to produce individualised intraradicular posts with a superior adaptation to the root canal (4,5). The eugenol residues of these sealers can remain on dentin walls and, like all phenols, they release free radicals that may interfere with the polymerisation of dental adhesives (8).

The aim of this study was to evaluate the bond strength between the fibre post and root dentin after different cleaning protocols to remove eugenol from dentin. The residues and elemental composition of dentin were analysed using SEM and EDS. Bovine incisor roots were obturated with eugenol-based sealer. The post space was prepared, and the roots were divided into the following groups according to the cleaning protocol: unfilled (negative control), saline solution (positive control), 70% ethanol, acetone and 70% isopropyl alcohol. The fibre posts were cemented and push-out test realised. Chemical analysis of the dentin was performed using SEM and EDS. The bond strength values were analysed by anova/Fisher's and were as follows: negative control (7.30 ± 2.77) = 70% ethanol (6.64 ± 2.91) = 70% isopropyl alcohol (5.01 ± 3.15) = acetone (4.42 ± 1.53) >positive control (1.29 ± 0.56). It was concluded that 70% ethanol may be a good cleaning protocol to remove eugenol from dentin.

“…However, some endodontic sealers contain eugenol, which interferes with adhesion of the resin cement to the radicular dentin (6)(7)(8)(9)(10). Eugenol diffuses into the dentinal tubules and can inhibit complete polymerisation of the resin cement (9,10).…”

“…Although there is a wide variability of endodontic sealers in the dental market with different compositions, studies that did not use endodontic resin sealers were excluded from the present study because canals obturated with eugenol-containing sealers may have reduced polymerization of resin cements used in GFPs cementation. [47][48][49] To standardize the samples, only studies that performed the bond strength test by using push-out test were included, since it is a commonly used test to evaluate FGPs as it provides a better estimate of the bond strength. 50 In relation to the treatment of the dentin surface for the removal of debris previous to FGPs cementation, there are several forms, such as aluminum oxide blasting, rotary brushes and irrigating solutions that are activated or not.…”

Can intra-radicular cleaning protocols increase the retention of fiberglass posts? A systematic review

et al. 2018

The presence of residues within the root canal after post-space preparation can influence the bond strength between resin cement and root dentin when using fiberglass posts (FGPs). Currently, there is no consensus in the literature regarding what is the best solution for the removal of debris after post-space preparation. This systematic review involved "in vitro" studies to investigate if cleaning methods of the root canal after post-space preparation can increase the retention of FGPs evaluated by the push-out test. Searches were carried out in PubMed (MEDLINE) and Scopus databases up to July2017. English language studies published from 2007 to July 2017 were selected. 475 studies were found, and 9 were included in this review. Information from the 9 studies were collected regarding the number of samples, storage method after extraction, root canal preparation, method of post-space preparation, endodontic sealer, resin cement, cleaning methods after post-space and presence of irrigant activation. Five studies presented the best results for the association of sodium hypochlorite (NaOCl) and ethylenediamine tetra-acetic acid (EDTA), while in the other 4 studies, the solutions that showed improved retention of FGPs were photoninduced photoacoustic streaming (PIPS), Qmix, Sikko and EDTA. The results showed heterogeneity in all comparisons due to a high variety of information about cleaning methods, different concentrations, application time, type of adhesive system and resin cements used. In conclusion, this review suggests that the use of NaOCl/EDTA results in the retention of FGPs and may thus be recommended as a post-space cleaning method influencing the luting procedure.

“…8 En el mismo año, Collares y col. realizaron un metaanálisis sobre la influencia del eugenol en la fuerza adhesiva de postes de fibra cementados en conductos radiculares, y concluyeron que el sellador a base de eugenol reduce la adhesión de postes de fibra cementados en raíces dentales con cemento de resina, sin importar el tipo de sistema adhesivo o cemento de resina utilizada. 9 Mosharraf y Zare en 2014, obtuvieron un resultado similar cuando compararon los selladores AHplus y Endofill: encontraron diferencias significativas que sugieren que el eugenol (Endofill) redujo significativamente la resistencia de la unión de los postes de fibra cementadas con cemento de resina. 10 Demiryürek y col. en 2010, evaluaron los efectos de tres selladores endodónticos en la adhesión de un poste de fibra unido con cemento de resina adhesiva.…”

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.
