fa Effect of Different Final Irrigants on Bond Strength of Resilon/Epiphany and Resilon/Epiphany Self-Etch ترمیمی Cosmetic and Restorative Dentistry پژوهشي Research <p> <strong>Objective:</strong></p><p>  To assess the effects of different final irrigants on the bond strength of bonded root filling materials, Epiphany/Resilon and Epiphany self-etch (SE)/Resilon. </p><p> <strong>Materials and Methods</strong>:</p><p>  The root canals of eighty single-rooted extracted human teeth were prepared. After the smear layer was removed using 17% EDTA, the samples were randomly divided into eight groups. In groups 1 and 2, no additional irrigant was used after EDTA. In the other groups, final irrigation was performed with 2.5% NaOCl (groups 3 and 4), 2% chlorhexidine (CHX) (groups 5 and 6), and normal saline (groups 7 and 8). The root canals were obturated with Epiphany/Resilon in groups 1, 3, 5 and 7 and obturated with Epiphany SE/Resilon in groups 2, 4, 6 and 8. After the middle thirds of the roots were horizontally sectioned, the push-out bond strength of root filling materials was assessed using the universal testing machine. The data were analyzed using Mann-Whitney and Kruskal-Wallis tests. The significance level was set at p<0.05. <strong></strong></p><p> <strong>Results:</strong> </p><p> There was no significant difference between the push-out bond strength of Epiphany/Resilon and Epiphany SE/Resilon (p>0.05). Considering the irrigation protocols, final irrigation with 2.5% NaOCl was associated with a significantly lower bond strength of both filling materials than the other irrigants (p<0.05). EDTA, CHX and normal saline had similar effects on the bond strengths of filling materials (p>0.05). </p><p> <strong>Conclusion:</strong></p><p>  Final irrigation of the root canals with 2.5% NaOCl following application of EDTA had a negative effect on the bond strength of Epiphany and Epiphany SE obturation systems. </p><hr><p></p><p> <strong>Source: </strong>Journal of Dentistry of Tehran University of Medical Science</p><p><a href="http://jdt.tums.ac.ir/index.php/jdt/article/view/861.pdf" target="_blank"><font color="#0000ff"> Full Text</font></a></p> Chlorhexidine; Epiphany Sealer; Sodium hypochlorite 0 0 http://idai.ir/browse.php?a_code=A-10-32-2636&slc_lang=fa&sid=1 Nosdhin Shokouhinejad shokouhinejad@yahoo.com 100319475328460012423 100319475328460012423 Yes Dental Research Center, Department of Endodontics, School of Dentistry, Tehran University of Medical Sciences, Tehran, Iran/Laser Research Center of Dentistry, Tehran University of Medical Sciences, Tehran, Iran Naghmeh Meraji 100319475328460012424 100319475328460012424 No Department of Endodontics, School of Dentistry, Tehran University of Medical Sciences, Tehran, Iran Ahmad Reza Shamshiri 100319475328460012425 100319475328460012425 No Dental Research Center, School of Dentistry, Tehran University of Medical Sciences, Tehran, Iran Mehrfam Khoshkhounejad 100319475328460012426 100319475328460012426 No Department of Endodontics, School of Dentistry, Tehran University of Medical Sciences, Tehran, Iran Maryam Raoof 100319475328460012427 100319475328460012427 No Oral and Dental Diseases Research Center/Department of Endodontics, Kerman University of Medical Sciences, Kerman, Iran
