Nanoparticle tracking analysis (NTA) size measurement experiments to observe the biomineralization. (A) Size differences observed in molar, canine, incisor and premolar protein extract at 0 hours, 6 hours and 12 hours in the presence of calcium phosphate; control experiments with only calcium phosphate (absence of protein) were shown. (B) Representative image taken by NTA. All four teeth extracts at 0 hours and after 12 hours were shown. Control images of only calcium phosphate were also shown. (C) Statistical analysis of NTA experiments.
