a, b Representative SEM image of resin dentin interface bonded using 50:50 CHX-MSN and 50:50:50 CHX-loaded/MSN-PLGA with their respective line EDX analysis exhibiting high percentage of amorphous carbon and silica along the line of resin-dentin interface. Note the amount of carbon increased with the grafting of PLGA over the MSN surface in 50:50:50 CHX-loaded/MSN-PLGA. c EDX mapping of resin matrix within hybrid layer from 50:50:50 CHX-loaded/MSN-PLGA showing nanoparticles distribution and the presence of carbon (C) and silica (Si) indicating MSN and PLGA within the resin matrix and distribution of nitrogen (N) and chlorine (Cl) as an evidence for chlorhexidine
