Effect of Different Final Irrigants on Bond Strength of Resilon/Epiphany and Resilon/Epiphany Self-Etch
چکیده:   (1808 مشاهده)

 Objective:

  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.

 Materials and Methods:

  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.

 Results:

 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).

 Conclusion:

  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.
