“…Erdemir et al (10) assessed the influence of two gutta-percha solvents (chloroform and halothane) on the microtensile bond strength to root canal dentin and observed that gutta-percha solvents have an adverse effect on the bond strength between adhesive cements and root canal dentin. Shokouhinejad et al (32) demonstrated that retreatment procedures might affect the adhesion of refilling materials to the dentinal walls, thus jeopardizing their bond strength to radicular dentin following endodontic retreatment. In this study, the chloroform used in retreatment had an adverse effect on the bond strength of Resilon/Epiphany SE after root canal reobturation.…”

The purpose of this study was to investigate the influence of gutta-percha solvents on the bond strength of fiberglass post to root canal dentin. Forty bovine incisors were decoronated, prepared, filled, and randomly distributed into four groups (n = 10) according to the gutta-percha solvent used: control, xylene, eucalyptol and orange oil. After root canal treatment, the posts were cemented into the prepared root canals using a resin-based cement. A micro pushout test was executed, and the patterns of failure were assessed with microscopy. The data were analyzed using two-way ANOVA followed by Tukey's test. The control group exhibited greater bond strength compared to the eucalyptol group in the cervical and middle thirds of the root (P < 0.05); however, it did not differ significantly from the xylene and orange oil groups (P > 0.05). No difference was observed in the values of the xylene, orange oil, and eucalyptol groups (P > 0.05). The cervical third had higher values than the apical third for all tested solvents (P < 0.05). Adhesive failure between resin cement and dentin was the most frequent type of failure. The use of xylene and orange oil as gutta-percha solvents did not influence the bond strength of fiberglass posts to root canal dentin. (J Oral Sci 56, 105-112, 2014)

“…[24][25][26][27][28] However, the effect of retreatment has not been so documented. Few studies have assessed the influence of this procedure on the bonding process, 29,30 despite the fact that retreatment is indicated when the initial procedure fails, 11,12 and therefore merits attention. Shokouhinejad et al 29 demonstrated that the chloroform used in retreatment had an adverse effect on the bond strength of Resilon/Epiphany SE.…”

Aim:The aim of this study is to evaluate the impact of endodontic retreatment on push-out bond strength and dentin interface of two resin cements used for fiber postcementation during endodontic retreatment. Materials and methods:The root canals of 40 extracted human canines were prepared, obturated and divided into four groups (n = 10). Gutta-percha was partially removed and fiber posts were immediately cemented in groups 1 and 2 using Panavia F with ED Primer and RelyX™ U200, respectively. In groups 3 and 4, the root canal access was sealed with temporary restorative cement, specimens were stored for 30 days, endodontically retreated, and fiber posts were cemented using the resin cements applied to groups 1 and 2, respectively. Push-out tests and scanning electron microscopy analyses of different areas were performed. Data from push-out bond strengths were analyzed by one-way analysis of variance and Tukey's tests. Results:Higher bond strength values were detected in the apical third for group 1 than group 3 (p < 0.05). No differences were observed in other comparisons between the same third of different groups (p > 0.05). Comparisons between different thirds in the same group revealed a higher bond strength in the apical third for group 1. Scanning electron microscopy showed formation of hybrid layer and extensive resin tags in group 1. No hybrid layer was observed in groups 2 and 4. Effect of Endodontic Retreatment on Conclusion:Endodontic retreatment had adverse effects on the push-out bond strength and dentinal interface of Panavia F with ED Primer when used for fiber postcementation specifically in the apical third, but not on RelyX™ U200.Clinical significance: A significant interaction was detected between endodontic retreatment and resin cement, which indicated that endodontic retreatment might adversely affect the push-out bond strength and dentinal interface of Panavia F with ED Primer when used for fiber postcementation specifically in the apical third.

“…Some of them have shown higher push-out bond strength for gutta-percha; 18-23 in one of them there were no significant differences. 24 It should be pointed out that in these studies gutta-percha and Resilon have been used with epoxy sealers and Epiphany. One of these studies showed that the bond strength of Epiphany + gutta-percha>AH-plus + gutta-percha>Epiphany + Resilon>AH-plus + Resilon.…”
