Representative FESEM micrographs of fractured dentin surfaces. (a) 15% PA-120 s group failed at the top of the hybrid layer; (b) Mixed failure happened at the top of hybrid layer was the most prevalent fracture mode in 10% PA-120 s group; (c) 2% CHX-120 s group presented adhesive failure; (d) Non-treated control group fractured at the bottom of the hybrid layer. FESEM, field emission scanning electron microscope; PA, proanthocyanidin; CHX, chlorhexidine.
