AB Functionalization is a promising approach for property improvement of endodontic substrates. The present thesis highlights the effect of dentin and gutta-percha surfaces’ functionalization on the adhesiveness between guttapercha/sealers/dentin interfaces, in view of a better obturation seal. We concluded that, despite no consensus being found about the effect of plasma treated dentin on the adhesion of resinous sealers it increased the adhesion of calcium silicate-based sealers. Functionalization of gutta-percha surfaces with Ar or O₂ plasma treatments increased roughness, surface free energy and wettability of the Endoresin and AH Plus Bioceramic, which might improve its adhesive properties. Plasma treated gutta-percha, coated with a nanostructured ZnO thin film enhanced the bond strength with endodontic sealers.
