Adhesion of self-adhesive root canal sealers on gutta-percha and Resilon.
BACKGROUND
The aim of this study was to evaluate the bond strength of different adhesive sealers on Resilon and gutta-percha.


METHODS
Pellets of gutta-percha and Resilon were embedded into test tubes. Small eyelets were attached to those surfaces with a 0.5-mm film of different root canal sealers. Real Seal, Real Seal SE, Hybrid Root Seal (also known as Meta Seal), and AH Plus were used. AH Plus as a nonadhesive sealer served as a control group. In all groups (n = 10) shear bond strength was measured.


RESULTS
Shear bond strength was relatively low (0.1-3 MPa) and significantly higher in the groups with a single component adhesive sealer. No substantial bond strength was found in the control group. Overall bond strength to Resilon was higher than to gutta-percha but not significant compared with the Hybrid Root Seal group.


CONCLUSIONS
With single component self-adhesive sealers, an adhesive connection might be formed to gutta-percha as well as to Resilon.
