Effect of Seashell and Eggshell Nanoparticles on Tooth Color Changes after Bleaching Using CIE L*C*H Color Space [PDF]

The Open Dentistry Journal, 2022
BackgroundDemineralization of dental structures is one of the post-bleaching effects. Remineralizing agents are recommended to overcome this problem. Synthesis of biomaterials from natural sources rich in calcium remains a viable and more economical option.
