Figure 3. FE-SEM micrographs of bonded interfaces in Adper Prompt L-Pop that were created by application of the adhesives with the experimental electric-assisted technique (a,c), or in accordance with the manufacturers’ instructions (b,d). Sites within the hybrid layer (H), with extensive silver deposits, corresponded with areas with extensive nanoleakage within the hybrid of the control specimen (B). A preferential localization of the silver deposits at the tubule orifices, while electricity reduced nanoleakage within the hybrid layer (A). A high-magnification view showing silver grains within the hybrid layer created with the use of the electric-assisted application. (D) A high-magnification image taken from a region with extensive nanoleakage, showing exposed collagen fibrils within the hybrid layer that were affiliated with silver grains (pointers) following control application. Dentin (D).
