The antibacterial efficiency of Chitosan photodynamically activated Phycocyanin, and Morinda Oleifera against S.mutans and the bonding strength between composite resin and caries-affected dentin.

Objective: Evaluation of contemporary disinfection techniques, Moringa Oleifera (M.Oleifera), Phycocyanin activated by photodynamic therapy (PDT), and Chitosan, on S.mutans survival rate and bond integrity of composite to carious-affected dentin (CAD).
