“…The main cause of failure is persistent, or recurrent microbial infection 2,3) . Nonsurgical retreatment is usually the preferred option for teeth in which endodontic treatment has failed as there is a greater opportunity to eradicate any intra-radicular source of infection compared with a surgical approach 4) .…”

“…[5] To increase the chances of a favorable outcome of root canal treatment, the infection within the root canal system should be eradicated effectively before obturation. [6] A periradicular lesion creates a barrier within the body which prevents further spread of microorganisms.…”

“…Nonsurgical endodontic retreatment is the first choice for resolving endodontic failures caused primarily by persistent root infections. [9][10][11][12] However, the action of the drills used to remove the root filling material produces a new smear layer rich in sealer and guttapercha remnants plasticized by the friction heat, 13 that mixed with inorganic components, can occlude dentinal tubules. 14 Furthermore, solvents are often used as an aid for removing gutta-percha 15 and result in the deposition of a thin layer of gutta-percha on root canal walls i.e., difficult both to detect and remove.…”

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.
