However, accurately repl...
(i.e., proteins and lipids that vary in composition depending on the tissue)17,18,19,20. Relative to enamel, bone and dentin are poorly mineralized (~60 to 70% wt.), with smaller bioapatite crystals and a higher organic fraction (30%) made up predominantly of collagen. The organic ...
